将用户输入从一个文本框复制到另一个文本框。 C＃ [英] Copying user input from one textbox to another. C#

问题描述

我是新手，对我这么光鲜。在VS 2k8 WPF中尝试这个



我正在尝试将用户的输入字符串从一个文本框复制到另一个文本框。当我这样做时，下面的工作正常：

I'm a newbie at this so bare with me. Trying this in VS 2k8 WPF

I'm trying to copy the user's input string from one text box to another. Below works fine when I do this:

private void buttonChange_Click(object sender, RoutedEventArgs e)
 {


     string userInput = boxTop.Text;
     boxBottom.Text = userInput;


 }

以下不起作用。我遗漏了一些非常基本的东西，希望能帮助你理解这一点。

Below doesn't work. I'm missing something very basic and would like some help understanding this.

private void buttonChange_Click(object sender, RoutedEventArgs e)
  {

      string userInput = boxTop.Text;
      string userOutput = boxBottom.Text;
      userOutput = userInput;



  }

推荐答案

private void buttonChange_Click(object sender, RoutedEventArgs e)
       {

           string userInput = boxTop.Text;
           string userOutput = boxBottom.Text;
           // Values saved in variables know you can change as you have done in first step.
           boxTop.Text = userOutput;
           boxBottom.Text = userInput;

       }
