Accessing variables from other namespaces

Question

I am new to C# and programming in general my question is how do you call a variable that is in a different namespace? if I have this code

public void servic         


        

Answer 1

To add to Andy's answer you can also shorten the call to the MyInt property by adding this above the My.Namespace declaration:

using My.Other.Namespace

If you do that then your call to the MyInt property would look like this:

int MyValue = MyOtherClass.MyInt

Answer 2

Normally, variables don't live in a namespace alone, they live inside another class that could be in another namespace. If you need to access a variable in another class (in another namespace), your other class needs to expose the variable somehow. The common practice for this is to use a public Property (static if you only need access to that variable) for the variable.

namespace My.Namespace
{
    public class MyClassA
    {
        public void MyMethod()
        {
            // Use value from MyOtherClass
            int myValue = My.Other.Namespace.MyOtherClass.MyInt;
        }
    }
}

namespace My.Other.Namespace
{
    public class MyOtherClass
    {
        private static int myInt;
        public static int MyInt
        {
            get {return myInt;}
            set {myInt = value;}
        }

        // Can also do this in C#3.0
        public static int MyOtherInt {get;set;}
    }
}

As a side node, it can be done by adding reference to the assembly in which the public members of another assembly are used. That's what incurred me.
