Compiler Warning (level 1) CS3001

Argument type 'type' is not CLS-compliant

A public, protected, or protected internal method must accept a parameter whose type is compliant with the Common Language Specification (CLS). For more information on CLS compliance, see Language independence and language-independent components.

Example

The following example generates CS3001:

// CS3001.cs  
  
[assembly:System.CLSCompliant(true)]  
public class a  
{  
    public void bad(ushort i)   // CS3001  
    {  
    }  
  
    private void OK(ushort i)   // OK, private method  
    {  
    }  
  
    public static void Main()  
    {  
    }  
}
