首先，建议将代码进行模块化，将不同的功能封装成独立的函数或模块，提高代码的可读性和可维护性。

其次，可以采用一些技巧来提高代码的性能，例如使用数组代替列表，使用StringBuilder代替字符串拼接等。

另外，建议使用常量代替魔法数字，使用枚举类型代替字符串常量，增加代码的可读性和可维护性。

最后，可以增加注释和文档说明，帮助其他开发人员理解代码的逻辑和用途。

Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet

xlWorkBook = xlApp.Workbooks.Add()
For i As Integer = 1 To 10
    xlWorkSheet = CType(xlWorkBook.Sheets.Add(), Excel.Worksheet)
    xlWorkSheet.Name = "Sheet " & i.ToString()
Next i

xlWorkBook.SaveAs("C:\example.xlsx")
xlWorkBook.Close()
xlApp.Quit()

多个表合并的代码示例：

Dim xlApp As New Excel.Application
Dim xlWorkBook As Excel.Workbook
Dim xlWorkSheet As Excel.Worksheet
Dim xlRange As Excel.Range
Dim lastRow As Integer

xlWorkBook = xlApp.Workbooks.Open("C:\example1.xlsx")
xlWorkSheet = xlWorkBook.Sheets(1)

vb.net 快速写入到excel的方法

在 VB.Net 中，我们可以使用 Microsoft.Office.Interop.Excel 命名空间来操作 Excel。

1. 创建一个 Excel 应用程序对象。

Dim excelApp As New Excel.Application

2. 创建一个 Excel 工作簿对象。

Dim excelWorkbook As Excel.Workbook

3. 打开 Excel 工作簿。

excelWorkbook = excelApp.Workbooks.Open("C:\MyWorkbook.xlsx")

4. 获取 Excel 工作表对象。

Dim excelWorksheet As Excel.Worksheet

excelWorksheet = excelWorkbook.Sheets("Sheet1")

5. 写入到单元格。

excelWorksheet.Cells(1,1) = "Hello World!"

6. 保存文件。

excelWorkbook.Save()

7. 关闭文件和 Excel 应用程序。

excelWorkbook.Close()
excelApp.Quit()

完整的代码示例：

Dim excelApp As New Excel.Application
Dim excelWorkbook As Excel.Workbook
excelWorkbook = excelApp.Workbooks.Open("C:\MyWorkbook.xlsx")
Dim excelWorksheet As Excel.Worksheet = CType(excelWorkbook.Worksheets("Sheet1"), Excel.Worksheet)
excelWorksheet.Cells(1,1) = "Hello World!"
excelWorkbook.Save()
excelWorkbook.Close()
excelApp.Quit()
