C# Error

CS0751 – A partial method must be declared within a partial type

Reason for the Error & Solution

A partial method must be declared in a partial class or partial struct

It is not possible to declare a method unless it is encapsulated inside a partial class or partial struct.

To correct this error

1. Either remove the partial modifier from the method and provide an implementation, or else add the partial modifier to the enclosing class or struct.

Example

The following example generates CS0751:

// cs0751.cs  
using System;  
  
public class C  
{  
    partial void Part(); // CS0751  
    public static int Main()  
    {  
        return 1;  
    }  
}
