Compiler Error CS1611

The params parameter cannot be declared as in ref or out

The keywords in, ref or out cannot be used with the params keyword.

The following sample generates CS1611:

// CS1611.cs  
public class MyClass  
{  
   public static void Test(params ref int[] a)   // CS1611, remove ref  
   {  
   }  
  
   public static void Main()  
   {  
      Test(1);  
   }  
}
