How to avoid from duplication code for returning similar object?

I am in a situation that i should duplicate some code. My code is in C#. So Here is my code:

public class Test
{
    public object Project1()
    {
        return new
        {
            Field1 = 1,
            Field2 = 2,
            Field3 = 3,
            Field4 = 4
        };
    }
    public object Project2()
    {
        return new
        {
            Field1 = 1,
            Field2 = 2,
            Field3 = 3,
            Field4 = 4,
            Field5 = 5,
            Field6 = 6,
            Field7 = 7,
            Field8 = 8
        };
    }
    public object Project3()
    {
        return new
        {
            Field1 = 1,
            Field2 = 2,
            Field3 = 3,
            Field4 = 4,
            Field5 = 5,
            Field6 = 6,
            Field7 = 7,
            Field9 = 9,
            Field10 = 10,
            Field11 = 11,
            Field12 = 12
        };
    }
}

I am searching for a good pattern if exists or not a good solution will be appreciated.
