Question

I have a combo box where I am displaying some entries like:

Equals
Not Equals 
Less Than
Greater Than

Notice that these strings contain spa

As of C# 8 you can do that using switches. In your example I believe the code would be like this.

enum Operation{Equals, Not_Equals, Less_Than, Greater_Than};

public static string OperationString(Operation opString) =>
    opString switch
    {
        Operation.Equals => "Equals",
        Operation.Not_Equals => "Not Equals",
        Operation.Less_Than=> "Less Than",
        Operation.Greater_Than=> "Greater Than",
        _   => throw new ArgumentException(message: "invalid enum value", paramName: nameof(opString )),
    };

See here for the documentation.
