我有一个关于Asp.net的问题 [英] I have a Question regarding Asp.net

问题描述

我已经使用了三个文本框.一是登录时间.另一个是注销时间.另一个是总时间.如果我要输入登录时间和注销时间，它将如何自动显示总时间.

ihave taken three textbox. one is login time. another is logout time.and another is total time.if i will insert the login time and logout time ,how automaticaly it will show the total time.

推荐答案

这里是一种可能的解决方案:

Here is one possible solution:

private void UpdateTotalTime()
{
  DateTime timeStart;
  DateTime timeEnd;
  if (DateTime.TryParse(textBox1.Text, out timeStart) && DateTime.TryParse(textBox2.Text, out timeEnd))
  {
    TimeSpan span = (timeEnd - timeStart);
    textBox3.Text = span.ToString("c");
  }
}

当两个输入文本框中的文本发生更改时，只需调用此函数即可.

Just call this function when the text in your two input textboxes changes.
