Is there a way to add additional values to the rectangle struct?

I want to add additional values to a rectangle. Like a "Name" string for example.

Something like this:

Rectangle MyRectangle = new Rectangle(Y, X, Width, Height, Name)

Is this possible?

There is two overload constructor function in Rectangle class.

public Rectangle(Point location, Size size);
public Rectangle(int x, int y, int width, int height);

But there isn't a constructor function parameter new Rectangle([int], [int], [int], [int], [string]) in Rectangle class.

You can try to use composite public Rectangle rect { get; set; } property in the class.

Then use constructor function to set Rectangle object and Name

public class CustomerRectangle 
{
    public Rectangle Rect { get; set; }
    public string Name { get; set; }
    public CustomerRectangle(int llx, int lly, int urx, int ury,string name) 
    {
        Rect = new Rectangle(llx, lly, urx, ury);
        Name = name;
    }
}

then you can use 

CustomerRectangle  MyRectangle = new CustomerRectangle (Y, X, Width, Height, Name);

//MyRectangle.Name; use Name property 
//MyRectangle.Rect; use Rectangle

I've seen others have contributed good examples, but in case of Cannot inherit from sealed type error, following example might help you:

public class myRectangle
{

    private Rectangle newRectangle = new Rectangle();
    private string name;

    public myRectangle Rectangle(Int32 Y, Int32 X, Int32 Height, Int32 Width, string name )
    {
       newRectangle.Y = Y;
       newRectangle.X = X;
       newRectangle.Height = Height;
       newRectangle.Width = Width;
       this.name = name;

       return this;
    }
}

I assume you are using a constructor from the System.Drawing namespace: https://learn.microsoft.com/en-us/dotnet/api/system.drawing.rectangle?view=netframework-4.7.2

It is not possible to add an extra field to that structure. What you can do is create your own class or structure which does contain more .

public class NamedRectangle
{
    public string Name { get; set; }

    public double X { get; set; }

    public double Y { get; set; }

    public double Width { get; set; }

    public double Height { get; set; }

    public NamedRectangle(double x, double y, double width, double height, string name)
    {
        Name = name;
        X = x;
        Y = y;
        Width = width;
        Height = height;
    }
}
