C# Unhandled exception has occurred in your application.

一个C#程序，在我計算機上運行沒有問題。一切順利。發布給別人時出的問題。Unhandled exception has occurred in your application.If you click Continue,the application will ignore this error and attempt to continue.If you click Quit,the application will close immediately.Object reference not set to an instance of an object.请问各位大神，这个如何解决？？？？异常C#
