Thanks in advance.

推荐答案

我不确定用户定义的文本框"是什么意思.
您的意思是您在运行时创建了一个，并且想要从中获取信息吗?
如果是这样，那么有两种方法可以实现:
1)创建它时，请将引用的副本保留在类级别变量中:

I am not sure what you mean by "userdefined textbox".
Do you mean you created one at runtime, and want to get the information from it?
If so, then there are two ways you can do that:
1) When you create it, keep a copy of the reference in a class level variable:

private TextBox myTextBox;
private void CreateTextBox(string initialText)
   {
   myTextBox = new TextBox();
   myTextBox.Text = initialText;
   Controls.Add(myTextBox);
   }

2)您可以通过迭代形式通过Controls数组访问它:

2) You can access it via the forms Controls array by iteration:

foreach (Control c in Controls)
   {
   TextBox t = c as TextBox;
   if (t != null)
      {
      Console.WriteLine(t.Text);
      }
   }

3)您可以给它命名，然后直接通过Controls数组访问它

3) You can give it a name, and access it directly via the Controls array

private void CreateTextBox(string initialText)
   {
   TextBox myTextBox = new TextBox();
   myTextBox.Text = initialText;
   myTextBox.Name = "RunTimeTextBox";
   Controls.Add(myTextBox);
   }
private TextBox GetRunTimeTextBox(string name)
   {
   return Controls[name] as TextBox;
   }

请注意，名称对于表单实例必须是唯一的！

如果这不是您要尝试的操作，我们将需要更多详细信息.

Note that the name must be unique to the form instance!

If this isn''t what you are trying to do, we will need more details.
