I got an internal method where one of the input parameter is an internal Enum. How do I get a enum value and pass it to the method?
Example:
internal enum MyEnum
{
One,
Two,
Three
}
internal int InternalTest(string test, MyEnum enumTest)
{
return test.Length;
}
And then obtained by something like this:
MethodInfo addInternal = typeof(Class1).GetMethod("InternalTest", BindingFlags.Instance | BindingFlags.NonPublic, null, new Type[] { typeof(string), typeof(?????) }, null);
Thanks!

If it is in a different assembly, then getting the type would have to be by name, for example;
Type type = assembly.GetType("SomeNamespace.SomeType+SomeNestedType");
Which might be (from the example):
Type type = typeof(Class1).Assembly.GetType("Class1+MyEnum");
A more interesting question is: how to get a value (boxed to the correct type) for the enum - you need something like:
object val = Enum.ToObject(type, 123);
Try typeof(Class1).GetNestedTypes()
. It should return a list all types that nested into Class1 - like MyEnum is. So look through the list of nested types, find the MyEnum type and pass it to GetMethod.
GetNestedTypes documentation on MSDN: http://msdn.microsoft.com/en-us/library/system.type.getnestedtypes(v=vs.100).aspx
There is also a GetNestedType()
method that accepts a type name and some BindingFlags which allows you to search for specific nested type by name.
To get a value of the enum using reflection, use this:
object enumValue = myEnumType.GetField("ValueName", BindingFlags.Static | BindingFlags.Public);
Get it by calling the GetNestedTypes()
method:
Type type = typeof(Program).GetNestedTypes().FirstOrDefault(x => x.IsEnum);
This will return the (arbitrary) enum in the type. If you want to find it by name or something, use a different lambda.
