如何返回与给定字符串匹配的枚举值？

Question

So I have a string and I want to get a value from an enum to return with the same name as string. Example:

enum Types{
    one,
    two,
    three
}

private Types getType(string value){   //Let's say value is "two"
    return Types.value;                //This should return the enum "two" of Types
}

I hope I made it clear enough!

Answer 1

使用Enum.Parse

var t = (Types)Enum.Parse(typeof(Types), "two");

Answer 2

If you're using .NET 4.0 or later, you can use the Enum.TryParse<TEnum> Method :

Types result;

if (Enum.TryParse<Types>("two", out result))
{
     // result == Types.two
}
