public sealed class Program
{
public static void Main()
{

Using ref with value types:
public sealed class Program
{
public static void Main()
{
Int32 x = 5; // x is initialized
AddVal(ref x); // x must be initialized.
Console.WriteLine(x); // Displays "15"
Console.ReadLine();
}
private static void AddVal(ref Int32 v)
{
v += 10; // This method can use the initialized value in v.
}
}
