Compiler Error CS0241

Default parameter specifiers are not permitted

Method parameters cannot have default values. Use method overloads if you want to achieve the same effect. For more information, see Passing Parameters (C# Programming Guide).

The following sample generates CS0241. In addition, the sample shows how to simulate, with overloading, a method with default arguments.

// CS0241.cs
public class A
{
   public void Test(int i = 9) {}   // CS0241
}

public class B
{
   public void Test() { Test(9); }
   public void Test(int i)  {}
}

public class C
{
   public static void Main()
   { 
      B x = new B();
      x.Test();
   }
}
