Compiler Error CS1670

params is not valid in this context

A number of C# features are incompatible with variable argument lists, and do not allow the paramskeyword, including the following:

  • Parameter lists of anonymous methods

  • Overloaded operators

The following sample generates CS1670:

// CS1670.cs
public class C
    public bool operator +(params int[] paramsList)  // CS1670
        return false;

    static void Main()
