I need to get paper size by System.Drawing.Printing.PaperKind. Are there any predefined values? I don\'t want to hardcode or calculate paper sizes, I just want to get it program

    Taking the comments and research by @hackerhasid, I reworked the deleted dotnet code for my own purposes returning a PaperSize class instead of a Point structure as done by the original code.

    I needed this in restricted security environments where printer access might be limited. I found that the restricted access prevented me from iterating over printer defined page sizes.

    A null is returned if the PaperKind is undefined or no longer supported.

    NOTE: The PaperSize class stores the numbers as hundredths of an inch.

        private static PaperSize GetPaperSize(PaperKind kind)
        {
            // NOTE: This code is a resurrected and refactored version of code originally found at:
            // http://www.dotnetframework.org/default.aspx/DotNET/DotNET/8@0/untmp/whidbey/REDBITS/ndp/fx/src/CommonUI/System/Drawing/Printing/PaperSize@cs/1/PaperSize@cs
    
            var fnInches = new Func((width, height) =>
            {
                Debug.Assert(width < 50 && height < 50, "You said inches, but you probably meant millimeters (" + width + ", " + height + ")");
                var ps = new PaperSize(kind.ToString(), (int)(width * 100), (int)(height * 100));
                ps.RawKind = (int)kind;
                return ps;
            });
    
            var fnMillimeters = new Func((width, height) =>
            {
                Debug.Assert(width > 50 && height > 50, "You said millimeters, but you probably meant inches (" + width + ", " + height + ")");
                var ps = new PaperSize(kind.ToString(), (int)(width / 25.4 * 100), (int)(height / 25.4 * 100));
                ps.RawKind = (int)kind;
                return ps;
            });
