Convert.ChangeType and converting to enums?

Enum.ToObject(.... is what you're looking for!

C#

StringComparison enumValue = (StringComparison)Enum.ToObject(typeof(StringComparison), 5);

VB.NET

Dim enumValue As StringComparison = CType([Enum].ToObject(GetType(StringComparison), 5), StringComparison)

If you do a lot of Enum converting try using the following class it will save you alot of code.

public class Enum<EnumType> where EnumType : struct, IConvertible
{

    /// <summary>
    /// Retrieves an array of the values of the constants in a specified enumeration.
    /// </summary>
    /// <returns></returns>
    /// <remarks></remarks>
    public static EnumType[] GetValues()
    {
        return (EnumType[])Enum.GetValues(typeof(EnumType));
    }

    /// <summary>
    /// Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
    /// </summary>
    /// <param name="name"></param>
    /// <returns></returns>
    /// <remarks></remarks>
    public static EnumType Parse(string name)
    {
        return (EnumType)Enum.Parse(typeof(EnumType), name);
    }

    /// <summary>
    /// Converts the string representation of the name or numeric value of one or more enumerated constants to an equivalent enumerated object.
    /// </summary>
    /// <param name="name"></param>
    /// <param name="ignoreCase"></param>
    /// <returns></returns>
    /// <remarks></remarks>
    public static EnumType Parse(string name, bool ignoreCase)
    {
        return (EnumType)Enum.Parse(typeof(EnumType), name, ignoreCase);
    }

    /// <summary>
    /// Converts the specified object with an integer value to an enumeration member.
    /// </summary>
    /// <param name="value"></param>
    /// <returns></returns>
    /// <remarks></remarks>
    public static EnumType ToObject(object value)
    {
        return (EnumType)Enum.ToObject(typeof(EnumType), value);
    }
}

Now instead of writing (StringComparison)Enum.ToObject(typeof(StringComparison), 5); you can simply write Enum<StringComparison>.ToObject(5);.
