推荐答案

从其他答案中，您可能已经掌握了要使用的技术.

From other answers, you probably got the techniques to use.

问题更加严重:从概念上讲，为什么需要重置?那是什么.

The problem is deeper: why do you need reset and what is that, conceptually.

针对一个类似的问题，我深入讨论了这个话题；请参阅 http://java.codeproject.com/Answers/305562/clearing- the-Csharp-form-contorls#answer3 [ ^ ].

I discussed this topic in depth, in response to a similar question; please see http://java.codeproject.com/Answers/305562/clearing-the-Csharp-form-contorls#answer3[^].

您可以循环进行控制

You can loop for control

foreach (Control ctrl in this)
{
        if(ctrl is TextBox)
                (ctrl as TextBox).Clear();
}

您可以编写循环以遍历表单中的所有控件，然后根据控件类型决定要执行的操作.
我将让您找出要放入大小写值的内容.

You could write a loop to go through all the controls in the form and then decide what to do based on the control type.
I''ll leave you to figure out what to put in the case values.

foreach( Control ctl in Controls )
{
   switch( ctl.GetType() )
   {
      case "TextBox": 
         ((TextBox)ctl).Text = string.Empty;

      case "ComboBox":
         ((ComboBox)ctl.SelectedIndex = -1;

      ...

   }
}
