Hi,

I would like to initialize a global variable inside a class during run time..is it possible?Any other way?

i.e console.writeline("Enter the path")

string path=console.readline();

Right now I have initialized only main method it works..however i have couple of other methods where this variable "path" should be used

What I have tried:

Tried placing out side the main method
declared the variable as static .. during execution it returns null

There are a couple of problems here: first off C# doesn;t have global variables: everything is within a class. The closest you can get is to have a static variable inside a class and that will be available to the whole code via the class name:

C#

public class MyClass
   {
   public static int globalValue = 666;
   ...
   }
...
public class MyOtherclass
   {
   private void MyMethod()
      {
      Console.WriteLine(MyClass.globalValue);
      }
   }

When you do that, you can use a static constructor for MyClass to initialize the variable:

C#

public class MyClass
    {
    public static string globalValue;
    static MyClass()
        {
        globalValue = File.ReadAllText(@"D:\Test Data\Primes.txt");
        }
    }

The static constructor will be called before the variable is used.
