Compiler Error CS1732

Expected parameter.

This error is produced when a lambda expression contains a comma following an input parameter but does not specify the following parameter.

To correct this error

  1. Either remove the comma, or add the input parameter that the compiler expects to find after the comma.

Example

The following example produces CS1732:

C#
// cs1732.cs  
// compile with: /target:library  
class Test  
    {  
        delegate void D(int x, int y);  
        static void Main()  
        {  
        D d = (x,) => { }; // CS1732  
      }  
    }
