将参数传递给linq表达式？

Question

I have the following code which converts ac# enum to javascript object but the types are invisible to the code and cause a compile time error. the types inside the stars are the problem, I guess that I need to pass the type into the linq expression but Im stock, does any one know how to do this?

public static string EnumToJsObj(Enum enumType)
{
    Type type = enumType.GetType();
    string strJS = string.Format("{{{0}}} ",
        string.Join(", ", Enum.GetNames(type).ToList().ConvertAll(key =>
        {
            return string.Format("{0} : {1}", key, (int)((***type***)Enum.Parse(typeof(***type***), key)));
        }).ToArray()));
}

Answer 1

Something like this?

public static string EnumToJsObj(Enum enumType)
{
    Type t = enumType.GetType();
    return new JavaScriptSerializer().Serialize(
            Enum.GetNames(t).ToDictionary(e => e, e => (int)Enum.Parse(t,e))
    );
}

You can either make your method to be a generic method:

public static string EnumToJsObj<T>(Enum enumType){ ... }

or you might be able to get away with using System.Convert.ChangeType instead of type casting.
