Set enum variable using int

[Guest]

I've read all the posts in this forum that I can find that look related to
this issue and I have only found 1 solution that I consider to be a bit of a
hack. What I want to do is assign a value to an enum variable using an int.
What I am using right now is something like this:

public enum MyEnum
{
value1,
value2,
value3
};

....

MyEnum var1;

// this value actually comes from a database so I can't substitute the
literal value
int intVar = 1;

var1 = (MyEnum)Enum.Parse(var1.GetType(), intVar.ToString());

Is there a simpler way to do this? It doesn't seem like setting the value
should require converting to string and then parsing and casting.

Have you tried just casting the integer value?

MyEnum m = (MyEnum)1;

Try this:

var1 = (MyEnum)intVar;


It works for me

var1 = (myEnum)intVar;

use

var1 = (MyEnum)intVar;

and don't forget to catch the exception because the values coming from
database may be out of your enum range.

public enum MyEnum : int
{
Value1 = 0,
Value2,
Value3
};

MyEnum var1 = (MyEnum) 1;
MyEnum var2 = MyEnum.Value2;
MyEnum var3 = (MyEnum) Enum.Parse(typeof(MyEnum), "Value3", true);

The above three can be done.

What I do, as a side note, is store the values in a database as the names of
the enumeration value. For example, I if I had MyEnum (as in the above
example), I would not store a value of 0, 1, or 2 into the database...I
would store the string "Value1", "Value2", or "Value3". I would then use
Enum.Parse() to convert the value to MyEnum. I do it this way "most of the
time" so users don't have to "guess" what those values are when they create
their AdHoc reports.

Hope this helps

No exception will be thrown with the above code - enums do no range
checking.
