Access variable from another method in another class

Question

Suppose I have a file ABC.CS in that file I have a class ABC as below and method Test():

public class ABC
{
   public          


        

Answer 1

Using static variables/functions is one thing; accessing a variable from outside of its scope is another thing.

From MSDN:

If a local variable is declared with the Static keyword, its lifetime is longer than the execution time of the procedure in which it is declared. If the procedure is inside a module, the static variable survives as long as your application continues running.

And also static variable will exist per class, not instance.

So, I assume that you will need instances of ABC class:

public class ABC
{ 
    private int a; //also you can add 'readonly' if you will not change this value in       its lifetime
    private int b;
    private int c;

    public int A()
    {
        get { return a; }
    }

    public int B()
    {
        get { return b; }
    }

    public int C()
    {
        get { return c; }
    }

    public void Test()
    {     
        a=10;
        b=11;
        c=12;
        //many many variables
    }
}

From another class you can call:

ABC abcInstance = new ABC();
abcInstance.Test(); //you set the values
int aTemp = abcInstance.A(); // now you have the 'a' value of ABC's property.
