Global.asax issue

Accessing and setting a gobal (static) variable are separate pieces in C#. You should look into the specifications of C#, as C# does not have the functionality you are trying to get.

I have never heard of this functionality in C#. Don't believe me right away though maybe there is (but I never heard of it ^_^). If you can't find a solution to this. You could always use a structure with public static fields. Or when using much variables a class with public static fields. Maybe this helps ^_^

Can anybody give me any advice on this?

Change to Application["msg"][0], I will get error "can't apply index with [] to an expression of type Object" So my question is: How to assign and access an application variable which has a type of string array? It seems not possible to do that in C# to me!

instead of ')' you use ']' so.. Application["msg"][0]
