Implementing "Union Type" for specific string values

Issue: Implement Implementing "Union Type" for specific string values without using Enum
Description:
In TypeScript, it is possible to define a set of specific values for a variable using union types, as shown in the example below:

type Status = 'pending' | 'received';

This approach is straightforward, avoids the creation of an enum, and can be used directly in string-type variables, keeping the code clean.

Currently, in C#, the common solution for this scenario is the creation of enums. However, creating an enum can sometimes be excessive when only a small number of fixed string values is needed. Additionally, enums restrict the flexibility of using string values directly.

Proposal:
Implement a simple way to define fixed string values without the need for enums to restrict the possible values that a string can hold.

public 'received' | 'pending' | 'progress' Status { get; set; }

I think using Enum is much more better than string like Python and TypeScript, but it can be more concise like record:

enum Status(Pending, Received, Prgoress);

Also if we can use string as Enum values, it will be more usefull:

enum Status {
  Pending = "pending",
  Received = "received",
  Progress = "progress"
}

and in concise way:

enum Status(Pending = "pending", Received = "received", Prgoress = "progress");

Your consice way:

enum Status(Pending, Received, Prgoress);

is longer (by a single character) than a regular enum, just replace () with {} and remove ; 😄

enum Status{Pending, Received, Prgoress}

String versions already exist. Just call ToString() on your value.

I don't think so, your way is OK if key and value be same, but for Pending = "Please Wait" it is not correct.

Yes, but you are breaking C# clean code rules :)... curly braces and enum values must be single in their lines...
