Pass in an enum as a method parameter

Question

I have declared an enum:

public enum SupportedPermissions {     basic,     repository,     both } 

I also have a POCO like this:

public class File {     public string Id { get; set; }     public string Name { get; set; }     public string Description { get; set; }     public SupportedPermissions SupportedPermissions { get; set; }       } 

Now I would like to create a method that I can use to create a new File object with:

public string CreateFile(string id, string name, string description, Enum supportedPermissions) {     file = new File     {           Name = name,         Id = id,         Description = description,         SupportedPermissions = supportedPermissions.basic     };      return file.Id; } 

How would I create the parameter for the enum and how would I assign that like in my pseudo code SupportedPermissions = supportedPermissions.basic so that my File instance has a SupportedPermissions set to it?

Answer 1

Change the signature of the CreateFile method to expect a SupportedPermissions value instead of plain Enum.

public string CreateFile(string id, string name, string description, SupportedPermissions supportedPermissions) {     file = new File     {           Name = name,         Id = id,         Description = description,         SupportedPermissions = supportedPermissions     };      return file.Id; } 

Then when you call your method you pass the SupportedPermissions value to your method

  var basicFile = CreateFile(myId, myName, myDescription, SupportedPermissions.basic);

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,               /* --> */  SupportedPermissions supportedPermissions) {     file = new File     {           Name = name,         Id = id,         Description = description,         SupportedPermissions = supportedPermissions // <---     };      return file.Id; } 

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <--- {     file = new File     {           Name = name,         Id = id,         Description = description,         SupportedPermissions = SupportedPermissions.basic // <---     };      return file.Id; }
