推荐答案

下面是示例代码

Here is sample code to do that

//Assumed you have saved your old password in database or someplace else(like a file or something) and it's retrieved and stored in var called OldPassword 


if(txtOldPassword.Text == OldPassword)
{
    if(txtNewPassword.Text == txtReEnterNewPassword.Text)
    {
         //Save the new password to database or where ever you want
    }
    else
    {
         //Show error mes saying new password does not match.clear the         text box and ask user to re-enter password.
    }
}
else
{
    //give the error mes saying the password provided is wrong and try again
}  

如果您是通过从工具箱添加登录组使用常规流程创建的，那么请查看 MSDN [ ^ ]并向下滚动到让用户更改密码

If you have created it using the normal process by adding a Login group from the toolbox, then look at MSDN[^] and scroll down to "Letting Users Change Their Password"
