推荐答案

取决于您如何显示Form2.
如果通过ShowDialog显示它，则必须添加一个返回代码作为属性(或使用DialogResult返回)，然后对其进行查询:

Depends on how you are showing the Form2.
If you show it via ShowDialog, then you will have to add a return code as a property (or use the DialogResult return) which you then interrogate:

Form2 f2 = new Form2();
if (f2.ShowDialog == DialogResult.OK)
   {
   if (f2.UpdatedOK)
      {
      myButton.BackColor = Color.Green;
      }
   }

如果使用Show而不是ShowDialog，则需要在Form2中创建第一个表单处理的事件.在处理程序中设置颜色.

If you use Show instead of ShowDialog, then you need to create an event in Form2 which your first form handles. In the handler you set the colour.

ButtonName.Background = Brushes.Red;

通过使用上面的代码，您可以动态更改按钮的颜色.

ButtonName.Background=Brushes.Red;

By using above code you can change button color dynamically.

我认为您应该在form2中使用委托来更改form1按钮的颜色，
