Hi,

I have a boolean variable like this:

[TypeConverter(typeof(MyBooleanConverter))]
private bool var = false;
From somewhere else in the code, I can access this variable only thanks
Click to expand...
to a memberInfo. To retrieve the attribute I do:

TypeConverterAttribute attrib =
(TypeConverterAttribute)Attribute.GetCustomAttribute(_memberInfo,
typeof(TypeConverterAttribute));

But now I don't now how to create the proper TypeConverter instance
from attrib.

Thank you for your help

Hi,
You can query for TypeConverterAttribute.ConverterTypeName which
returns the full name of the custom type converter and the load the
same type using Type.GetType( <typename>).
Here I'm adding the code snippet for instantiating a custome type
converter from TypeConverter attribute

TypeConverterAttribute attrib =
(TypeConverterAttribute)Attribute.GetCustomAttribute(_member­Info,
typeof(TypeConverterAttribute));
MyBooleanConverter attr =
(MyBooleanConverter)Activator.CreateInstance(Type.GetType(attrib.ConverterTypeName),
false);
