c# - How to get enum value by string or int

Question

How can I get the enum value if I have the enum string or enum int value. eg: If i have an enum as follows:

public enum TestEnum
{
    Value1 = 1,
    Value2 = 2,
    Value3 = 3
}

and in some string variable I have the value "value1" as follows:

string str = "Value1" 

or in some int variable I have the value 2 like

int a = 2;

how can I get the instance of enum ? I want a generic method where I can provide the enum and my input string or int value to get the enum instance.

Answer 1

No, you don't want a generic method. This is much easier:

MyEnum myEnum = (MyEnum)myInt;

MyEnum myEnum = (MyEnum)Enum.Parse(typeof(MyEnum), myString);

I think it will also be faster.
