C# Error

CS0833 – An anonymous type cannot have multiple properties with the same name

Reason for the Error & Solution

An anonymous type cannot have multiple properties with the same name.

An anonymous type, just like any type, cannot have two properties that have the same name.

To correct this error

1. Give each property in the type a unique name.

Example

The following example generates CS0833:

// cs0833.cs  
using System;  
  
public class C  
{  
    public static int Main()  
    {  
        var c = new { p1 = 1, p1 = 2 }; // CS0833  
        return 1;  
    }  
}
