Get int value from enum in C#

public enum QuestionType
{
    Role = 2,
    ProjectFunding = 3,
    TotalEmployee = 4,
    NumberOfServers = 5,
    TopBusinessConcern = 6
}

...is a fine declaration.

You do have to cast the result to int like so:

int Question = (int)QuestionType.Role

Otherwise, the type is still QuestionType.

This level of strictness is the C# way.

One alternative is to use a class declaration instead:

public class QuestionType
{
    public static int Role = 2,
    public static int ProjectFunding = 3,
    public static int TotalEmployee = 4,
    public static int NumberOfServers = 5,
    public static int TopBusinessConcern = 6
}

It's less elegant to declare, but you don't need to cast it in code:

int Question = QuestionType.Role

Alternatively, you may feel more comfortable with Visual Basic, which caters for this type of expectation in many areas.
