以下是一个基于 C# 的窗体修改密码的示例代码:
```csharp
// 修改密码窗体
public class ChangePasswordForm : Form
{
private TextBox oldPasswordTextBox;
private TextBox newPasswordTextBox;
private TextBox confirmPasswordTextBox;
private Button confirmButton;
// 构造函数
public ChangePasswordForm()
{
// 初始化控件
this.oldPasswordTextBox = new TextBox();
this.newPasswordTextBox = new TextBox();
this.confirmPasswordTextBox = new TextBox();
this.confirmButton = new Button();
this.confirmButton.Click += new EventHandler(confirmButton_Click);
// 添加控件到窗体
this.Controls.Add(this.oldPasswordTextBox);
this.Controls.Add(this.newPasswordTextBox);
this.Controls.Add(this.confirmPasswordTextBox);
this.Controls.Add(this.confirmButton);
}
// 确认按钮的 Click 事件处理函数
private void confirmButton_Click(object sender, EventArgs e)
{
// 获取用户输入的密码
string oldPassword = this.oldPasswordTextBox.Text;
string newPassword = this.newPasswordTextBox.Text;
string confirmPassword = this.confirmPasswordTextBox.Text;
// 验证旧密码是否正确
if (!VerifyOldPassword(oldPassword))
{
MessageBox.Show("旧密码不正确,请重新输入。");
this.oldPasswordTextBox.Clear();
this.newPasswordTextBox.Clear();
this.confirmPasswordTextBox.Clear();
return;
}
// 验证新密码和确认密码是否一致
if (newPassword != confirmPassword)
{
MessageBox.Show("新密码和确认密码不一致,请重新输入。");
this.newPasswordTextBox.Clear();
this.confirmPasswordTextBox.Clear();
return;
}
// 更新数据库中的密码
UpdatePassword(newPassword);
MessageBox.Show("密码修改成功。");
this.Close();
}
// 验证旧密码是否正确
private bool VerifyOldPassword(string oldPassword)
{
// 从数据库中获取当前用户的密码
string currentPassword = GetCurrentUserPassword();
// 验证旧密码是否正确
return (oldPassword == currentPassword);
}
// 更新数据库中的密码
private void UpdatePassword(string newPassword)
{
// 获取当前用户的用户名
string userName = GetCurrentUserName();
// 使用更新 SQL 语句更新密码
string updateSql = string.Format("UPDATE users SET password='{0}' WHERE username='{1}'", newPassword, userName);
ExecuteSql(updateSql);
}
// 获取当前用户的用户名
private string GetCurrentUserName()
{
// TODO: 获取当前用户的用户名
return "test";
}
// 获取当前用户的密码
private string GetCurrentUserPassword()
{
// TODO: 从数据库中获取当前用户的密码
return "123456";
}
// 执行 SQL 语句
private void ExecuteSql(string sql)
{
// TODO: 执行 SQL 语句
}
}
```
以上代码仅为示例,具体实现方式可以根据具体需求进行调整和优化。
