C# class within a class (or nesting)?

Question

Hey all I have made the following class: public class ssrsFormats { public static readonly string pdf = "PDF", mhtml = "MHTML", html4 = "HTML4.0", html3 = "HTML3.2", excel1 = "EXCELOPENXML", excel2 = "EXCEL", word1 = "WORDOPENXML", word2 = "WORD", csv = "CSV", xml = "XML", image = "IMAGE"; } And what I am wondering is how (if) I can do something like so: ssrsFormats.image.jpeg I only want to do this so I have a type of **"intellisense"** in order to help me build the function call when it comes to that. Instead of me trying to remember the image formats within the SSRS formats class, I start typing **ssrsformats.image.** and it pops up the image formats for me to pick from. I am trying to also do this **within one class** instead of having multiple classes that point to other classes.

Look into the enumeration type (enum) for your ssrsFormats.

See: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/enum

You can create two enums, one for your main format type and a second for your image type. Or you can add a reference to System.Drawing and use the built in image formats via System.Drawing.Imaging.ImageFormat

Below is a sample class using enums instead of your static ssrsFormats:

public enum ssrFormats

{

pdf,

mhtml,

html4,

image

}

public enum imageType {

jpg,

png,

bmp

}

class Program

{

static void Main(string[] args)

{

ssrFormats reportFormat = ssrFormats.image;

imageType reportImageType = imageType.png;

}

}
