Compiler Error CS0746

Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.

An anonymous type must be declared with a member assignment, simple name, or member access.

To correct this error

• Ensure that your declaration uses only member assignment, simple names, or member access expressions.

Example

The following code generates CS0746 in the declaration of incorrect_1 and incorrect_2. The following declarations show two of the correct ways to declare an anonymous type.

// cs0746.cs
public class C
{
    public static int Main()
    {
        int i = 100;
        string s = "Bottles of beer.";

        var incorrect_1 = new { a.b = 1 }; // CS0746 
        var incorrect_2 = new {100, "Bottles of beer."}; // CS0746
        var correct_1 = new { i, s }; //OK
        var correct_2 = new {num = i, message = s}; // OK

        return 1;
    }
}
