How to convert enum to int

Question

In C# we can convert an enum to an int by static typecasting as shown below:

int res = (int)myEnum;

Is any other way to do this conversion?

There are plenty of other ways (including Convert.ToInt32 as mentioned by acrilige), but a static cast is probably the best choice (as far as readability and performance are concerned)

Best would be:

int res = Convert.ToInt32(myEnum);

OR a static cast

int res = (int)myEnum;

Here is an example enum:

public enum Books
{
    cSharp = 4,
    vb = 6,
    java = 9
}

Then the code snippet to use would be:

Books name = Books.cSharp;
int bookcount = Convert.ToInt32(name);
