You can use a union:

public struct A
{
    int x, y;
    double a, b;

    public A(int x, int y, double a, double b)
    {
        this.x = x;
        this.y = y;
        this.a = a;
        this.b = b;
    }
}
public struct B
{
    int x, y;
    double a, b;
}

[StructLayout(LayoutKind.Explicit)]
public class Union
{
    [FieldOffset(0)]
    public A a;
    [FieldOffset(0)]
    public B b;

    public Union(A a)
    {
        this.b = default(B);
        this.a = a;            
    }
}

class Program
{
    static void Main(string[] args)
    {
        A a = new A(5, 10, 0.25, 0.75);
        Union union = new Union(a);
        B b = union.b; //contains 5,10,0.25,0.75
    }
}
