Compiler Error CS1503

Argument 'argument' cannot convert from TypeA to TypeB

The type of one argument in a method does not match the type that was passed when the class was instantiated.

The following sample generates CS1503:

C#

namespace x
{
  public class a
  {
    public a(char i)
    // try the following constructor instead
    // public a(int i)
    {
    }

    public static void Main()
    {
      a aa = new a(2222);   // CS1503
    }
  }
}
