这应该这样做：


TextBox someTextBox =

myForm.GetType（）。GetFields（" MyTextBox"）。GetValue（m yForm）为TextBox;

news：04 **************************** @ phx.gbl ... 如何通过传递名称来获取对表单上控件对象的引用。像TextBox txt = SomeClass.SomeGetObjectMethod

wheras SomeClass和SomeGetObjectMethod是我正在寻找的东西。
提前致谢。

对我不起作用。我想它应该是GetField（结尾没有

" s"）但是即便如此它还没有工作并给出空引用

例外。

这应该这样做：

TextBox someTextBox =
myForm.GetType（）。GetFields（" MyTextBox"）。GetValue（ m yForm）as TextBox;

请发一个简短但完整的例子。请参阅

This should do it:

TextBox someTextBox =
myForm.GetType().GetFields("MyTextBox").GetValue(m yForm) as TextBox;

Did not work for me. I guess it should be GetField (ending without
"s") but even then its not working and giving null reference
exception.

Please post a short but complete example. See
