Compiler Error CS0747

Visual Studio 2008

Invalid initializer member declarator.

An object initializer is used to assign values to properties or fields. Any expression which is not an assignment to a property or field is a compile-time error.

To correct this error

  • Ensure that all expressions in the initializer are assignments to properties or fields of the type. In the following example, the second expression is an error because the value 1 is not assigned to any property or field of List<int>.

The following code generates CS0747:

// cs0747.cs
using System.Collections.Generic;

public class C
{
    public static int Main()
    {
        var t = new List<int> { Capacity = 2, 1 }; // CS0747
        return 1;
    }
}
