The solutions given there are fairly accurate and should help you out.

假设您希望使用类型int.验证文本框属性Text的唯一可靠方法是调用int.TryParse(string).

请参阅 http://msdn.microsoft.com/en-us/library/f02979c7.aspx [ ^ ].

其他所有整数类型也是如此.

Suppose you expect the type int. The only reliable way to validate the property Text of the text box is to call int.TryParse(string).

See http://msdn.microsoft.com/en-us/library/f02979c7.aspx[^].

Same thing goes for all other integer types.
