C#检查foreach判读是否为null的方法

为避免这种情况，我们需要在遍历前检查集合是否为null。本文将详细介绍如何在C#中通过扩展方法来优雅地处理这个问题。首先，让我们看看常规的做法。当遍历一个列表或数组时，我们需要在foreach之前添加一个...

getList(page, fenlei, ref = '') { if(fenlei == '全部') this.swiperIndex = -1; for(let i=0;i<this.fenlei.length;i++) { if(fenlei == this.fenlei[i]) { this.swiperIndex = i; break; } } this.curFenlei = fenlei; if (this.curFenlei == '全部') { this.isPlain = false; } else { this.isPlain = true; }

首先判断分类是否为“全部”，如果是则把swiperIndex设置为-1，否则遍历分类数组this.fenlei并找到对应的分类，把swiperIndex设置为对应的索引值。然后将当前分类赋值给curFenlei变量，并根据curFenlei是否为“全部...

fetchData() { // this.list = [] this.listLoading = true this.good.pageSize = this.pageSize this.good.pageIndex = this.currentPage4 console.log(this.good.uintPirce) if (this.good.uintPirce === '' || this.good.uintPirce === null) { this.good.uintPirce = 0 } getList(this.good).then(response => { this.list = response.data.records this.total = response.data.total this.pageSize = response.data.size // this.total = response.data.pages this.currentPage4 = response.data.current this.listLoading = false }) },解释以上每一行代码

3. this.good.pageIndex = this.currentPage4: 将 good 对象的 pageIndex 属性设置为当前的 currentPage4 值。 4. console.log(this.good.uintPirce): 打印出 good 对象的 uintPirce 属性的值，用于...

getList(page, fenlei, ref = '') { let params = {page, limit: this.pageSize}; let searchWhere = {}; if (this.formSearch.jingdianmingcheng != '') searchWhere.jingdianmingcheng = '%' + this.formSearch.jingdianmingcheng + '%'; this.$http.get('quxiaogoupiao/list', {params: Object.assign(params, searchWhere)}).then(res => { if (res.data.code == 0) { this.dataList = res.data.data.list; this.total = res.data.data.total; this.pageSize = res.data.data.pageSize; this.totalPage = res.data.data.totalPage; this.pageSizes = [this.pageSize, this.pageSize2, this.pageSize3, this.pageSize*5]; } }); },

参数page表示当前页码，fenlei表示分类，ref表示引用，但似乎没有被使用。方法中首先定义了一个params对象，用于存储请求参数，包括当前页码和每页数据条数。然后定义了一个searchWhere对象，用于存储搜索...

async getList() { this.finished = false; this.loading = true; const data = await this.$axios.post( "/tax/temp/wechat/contract/queryOverSign", { openId: this.userInfo.openId, page: { page: this.pageNo, }, } // { // headers: { // ssessionid: sessionStorage.getItem("sessionId"), // }, // } ); if (data.success) { const { list, total, pages } = data.data; this.list = [...this.list, ...list]; this.total = total; if (this.pageNo < pages) { this.pageNo++; } else { this.finished = true; } } this.loading = false; this.showLoading = false; },这个接口中会把传参变为page%5Bpage%5D=1这种格式，前端传参该如何保证传参格式还是为json

在前端传参时，可以使用 params 参数来保证传参格式为 JSON。修改代码如下： javascript const data = await this.$axios.post( "/tax/temp/wechat/contract/queryOverSign", { openId: this.userInfo....

if (this.data.tabIndex != i && !this.data.isLoading) { this.setData({ tabIndex: i, couponShowList: [] }) this.currentPage = 0 this.totalPage = 1 if (this.data.tabIndex == 0) { this.setData({ type: 1, showEmpty: false }) } else if (this.data.tabIndex == 1) { this.setData({ type: 2, showEmpty: false }) } else if (this.data.tabIndex == 2) { this.setData({ type: 3, showEmpty: false }) } this.getList() } 转uniapp 格式

请问您是想将这段代码转换为uniapp格式吗？转换后的代码如下： if (this.data.tabIndex !== i && !this.data.isLoading) { this.setData({ tabIndex: i, couponShowList: [] }); this.currentPage = 0; this....

const getList = async() => { tableLoading.value = true const params = { ...searchParams, ...pagination } if (params.atomization !== null && params.atomization !== '') { params.state = true } console.log("---------params---------"); console.log(params); const test = await listOverviewt(params) console.log("test",test.code) // listOverviewt(params).then(res => { // tableLoading.value = false // if (res.code !== '0000') { // return // } // const { list, total } = res.data // dataSource.value = list // // console.log("list",list[1].furnaceStartTime) // pagination.total = total // }).catch(() => { // tableLoading.value = false // }) tableLoading.value = false; if(test.code !== '0000'){ console.log("11111") return } const { list, total } = test.data dataSource.value = list for(let i = 0;i<dataSource.value.length;i++){ let str = dataSource.value[i].furnaceStartTime; if(dataSource.value[i].furnaceStartTime == null){ // dataSource.value[i].furnaceStartTime == "未开炉" }else{ // str = str.split('T') // str[1] = str[1].split('.') // let testStr = str[0]+'-'+str[1][0] dataSource.value[i].furnaceStartTime = moment(dataSource.value[i].furnaceStartTime).format('YYYY-MM-DD HH:mm:ss') // console.log("dataSource",str[0]+'-'+str[1][0]) } } pagination.total = total }

这段代码看起来像是一个 Vue.js 组件中的 async 函数，它首先将 tableLoading 设为 true，然后将搜索参数和分页参数合并到 params 对象中，并且根据 params.atomization 的值来设置 params.state 的值。...

private void gvbind() { //商品类别业务逻辑层 BLL.CPInfoBusiness busi = new BLL.CPInfoBusiness(); DataSet ds = new DataSet(); //加载业务列表 ds = busi.GetList(""); PagedDataSource objPds = new PagedDataSource(); objPds.DataSource = ds.Tables[0].DefaultView; objPds.AllowPaging = true; objPds.PageSize = 16; int CurPage; if (Request.QueryString["Page"] != null) CurPage = Convert.ToInt32(Request.QueryString["Page"]); else CurPage = 1; objPds.CurrentPageIndex = CurPage - 1; lblCurrentPage.Text = CurPage.ToString(); lblSumPage.Text = objPds.PageCount.ToString(); if (!objPds.IsFirstPage) { this.hyfirst.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + 1; lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage - 1); } if (!objPds.IsLastPage) { hylastpage.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + objPds.PageCount; lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurPage + 1); } this.DataList1.DataSource = objPds; this.DataList1.DataBind(); }

在该函数中，首先实例化了一个BLL.CPInfoBusiness对象，用于从数据库中获取数据。 2. 获取数据并进行分页通过调用BLL.CPInfoBusiness对象的GetList("")方法，获取数据并赋值给DataSet对象ds。然后，将ds.Tables[0...

优化代码if(this.form.deptCadre == 1 ){ this.form.sendInvoice = 0 updateDept(this.form).then(response => { this.$modal.msgSuccess("修改成功"); this.open = false; this.getList(); }); }else{ updateDept(this.form).then(response => { console.log(this.form); this.$modal.msgSuccess("修改成功"); this.open = false; this.getList(); }); }

这段代码的逻辑是，如果 this.form.deptCadre 的值为 1，则将 this.form.sendInvoice 的值设为 0，并执行 updateDept 函数进行部门信息的更新操作。更新成功后，弹出修改成功的提示框，关闭弹窗，并重新获取...

methods: { selectstaff(facultyId) { if (facultyId) { selectstaff({ facultyId }).then(response => { this.staffNumber = response.data; }); } else { this.staffNumber = []; } }, /** 查询一级审核人员管理列表 */ getList() { // 调用获取学院信息和员工编号信息的方法 this.selectfaculty(); this. selectstaff(this.form.facultyId); }, change_faculty() { this.selectstaff(this.form.facultyId); // pass the selected faculty id as an argument this.form.firstStaffNumber = []; // reset the first staff number when faculty changes this.form.firstStaffName = []; // reset the first staff name when faculty changes }, change_selsect(){ // console.log("jinlai") for(const staffss of this.staffNumber){ // console.log(staffss.staffNumber+"aaa") if(staffss.staffNumber==this.form.firstStaffNumber){ this.form.firstStaffName = staffss.staffName } } },以上这段代码在选择学院时一级审核人员工号依旧获得全部的

在 getList 方法中，你首先调用了 selectfaculty 方法，然后再调用 selectstaff 方法。但是，你没有等待 selectfaculty 方法完成，就立即调用了 selectstaff 方法，并且传递了 this.form.facultyId 参数...

this.formData = Object.assign({}, this.editingData); }, 这样，当弹窗弹出时，表单中就会显示要编辑的数据的初始值。当用户修改了数据并点击保存按钮后，再将表单中修改后的数据提交到后台进行更新。

onSearch: function () { if (this.searchInput) this.queryByName = { searchInput: this.searchInput } else this.queryByName = {} this.data.list = [] this.getList() },j指出这段代码存在哪些问题/

1. 检查用户输入的搜索关键字是否存在，如果存在则将其作为查询参数 searchInput 存入 queryByName 对象中，否则将 queryByName 初始化为空对象。 2. 将列表数据 list 清空。 3. 调用 getList() 方法，...

getFamily(id) { this.loading = true; listFamily({ studentId: id, pageNum: 1, pageSize: 99 }).then(response => { this.tableData = response.rows; this.loading = false; }); }, /** 查询招生信息列表 */ getList() { this.loading = true; listInformation(this.queryParams).then(response => { this.informationList = response.rows; this.total = response.total; this.loading = false; }); }, 怎么把this.tableData中的realName的值给this.informationList下的guardian

可以使用循环遍历的方式，将 this.tableData 中的 realName 值赋给 this.informationList 下的 guardian 属性。具体实现代码如下： for(let i = 0; i < this.tableData.length; i++) { this....

这段代码是 Vue.js 组件的 created 钩子函数，当组件被创建时会自动调用。具体实现的功能如下： ...- 调用 getList 方法，获取列表数据，默认传入页码为 1，分类为全部。 - 调用 getHotList 方法，获取热门数据列表。
