Using custom TypeConverter outside of PropertyGrid

[Cartoper]

I have written all these wonderful custom TypeConverter for my enums
to display in a PropertyGrid. I would now like to use the same
TypeConverter to save out and read in the values to and from a text
file, in a generic fashion. I would like to have a function like
this:

void WriteValue(StreamWriter sw, string name, Enum value);

As I walked to lunch it dawned on me that I might be able to get at
the attributes via the GetType() method. Well, I wasn't able to, but
I did realize that as long as you follow the convention of <enum
name>TypeConverter, that through reflections you can instanciate the
enum's TypeConverter:

// start by using the default ToString method
string valueStr = Value.ToString();

try
{
// Get the enum type
Type enumType = Value.GetType();

// Get the enum name and then add the TypeConverter to the end of it
string typeConverterName = enumType.FullName + "TypeConverter";

// Get the assembly that the enum is in.
string assemblyName = enumType.Assembly.FullName;

// try to create the type converter
ObjectHandle objHandle =
Thread.GetDomain().CreateInstance(assemblyName, typeConverterName);

// Get the TypeConverter from the object handle
TypeConverter typeConverter = objHandle.Unwrap() as TypeConverter;

// Convert it to a string
valueStr = typeConverter.ConvertToString(Value);
}
catch(Exception)
{
}

Or just TypeDescriptor.GetConverter(enumType) ;-p

or in fact TypeDescriptor.GetConverter(Value);

I'm also assuming that the enum is marked with TypeConverterAttribute
