I need to be able to enumerate through values of an enumerator in a separate assembly for which I only have the assembly qualified name.
I am able to determine the assembly qualified name, but I can't resolve the 'The requested operation is invalid in the ReflectionOnly context.' when I try to enumerate it.
My main code, in assembly DevExample:
using System;
using ClassLibrary;
namespace DevExample
{
public class Program
{
static void Main(string[] args)
{
Type myEnumType = MyEnum.One.GetType();
WriteToConsole(myEnumType);
Type myEnumType_null = Type.GetType(myEnumType.FullName); // will return null
string assemblyName = myEnumType.AssemblyQualifiedName;
// assemblyName will be "ClassLibrary.MyEnum, ClassLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null";
Type myEnumTypeFromReflection = Type.ReflectionOnlyGetType(assemblyName, true, false); // Will get type succesfully
WriteToConsole(myEnumTypeFromReflection);
}
private static void WriteToConsole(Type enumType)
{
foreach (int val in Enum.GetValues(enumType))
{
Console.WriteLine("{0} - {0}", Enum.GetName(enumType, val));
}
}
}
}
Then in another assembly (ClassLibrary.dll) I just defined a simple enumerator
namespace ClassLibrary
{
public enum MyEnum
{
Zero = 0,
One = 1,
Two = 2
};
}
On the second write to console, I get:
The requested operation is invalid in the ReflectionOnly context.
I need to do this to validate an .xml that defines which enumerators a particular piece of hardware is using.
Previous code has just loaded a dictionary with the name and types manually, but given that the .xml file is able to contain the assembly qualified name, it should be able to do this dynamically.
