Hi all,

I am a little confused with C#.NET.

When I develop an app using VB.NET, I can use Module.
I declare public variable in this module and access it from all part of the project.

But, when I change to C#.Net, there is no module in C#.NET.

How should I proceed?

How do I declare Global Variable in C#.NET?

Please Help...

C# has no concept of global variables: everything is class scope.
However (just like VB) you can declare a static class and access everything in it as if they were global:

public static class Globals
   {
   public static int MyGlobalValue = 42;
   }

...


private void MyMethodSomewhereInAClass()
   {
   Console.WriteLine(Globals.MyGlobalValue);
   MyGlobalValue += 23;
   }

Technically, the class does not need to be static, but since you should not need to instatiate it, it is a good idea.

Agree with the Answer. My 5.

class MyClass {
    public int MemberOne;
    internal int MemberTo = 13; //can initialize
    internal protected string MemberThree;
    private System.DataTime Time; //can omit "private": default for class/struct
    //property, one of several forms of declaration:
    public int MemberFour { get; set; } 
}

In intentionally listed all access modifiers: learn them all.
As a rule of thumb, public fields should be discouraged and properties preferred.

Now, asking questions like that will waste anyone's time and get you nowhere. First, read a manual and do exercises. Read my non-nonsense instructions:
I have a problem with my program. Please help![^].

Don't forget this: What are Apache Struts and JBoss Hibernate[^]. (Ignore the topic, read my Answer.)

Good luck.
