推荐答案

看看此处 [ ^ ]

此当您尝试使用属性或调用对象的方法为null时，会发生错误.更多详细信息:此处 [

This error happens when you try to use a property or call a method of an object that is null. More details: here[^]

A simple use of Visual studio DEBUGGER can tell you the object because of which it is happening. Just look at the stack trace and put a debugger on that line. Check the objects of that line and see if any one is null and you are trying to use that objects property. Handle the same.

Above, looks like objDyn is NULL or one of the parameters passed assuming error is not raised in GenerateTabControls method.

在page_load上将此代码写入page_init

write this code on page_load in place page_init
