I'm trying to get a list of all the member functions of my class, but nothing has worked as of yet. Here's my most recent attempt:


Type type = Type.GetType("BackgroundGenerator.Generator");
MemberInfo[] arMemberInfo = type.GetMembers(
			//BindingFlags.LookupAll |
			BindingFlags.DeclaredOnly 
			);

The GetType call seems to work, but arMemberInfo ends up with nothing in it. Notice also I've commented out LookupAll, as it doesn't seem to exist anymore (but lots of good examples use it). Has this been deprecated? I can get single methods like this: MethodBase method = type.GetMethod("Method1"); Generator is the class I'm interested in, and has plenty of member functions. I can post more code if that would be helpful. I'm new to C#, so any help would be great.

From the System.Type.GetMembers() documentation on MSDN:

You must specify either BindingFlags.Instance or BindingFlags.Static in order to get a return.

Basically, do an or with your BindingFlags parameter with either BindingFlags.Instance or BindingFlags.Static and you should get a return.

I think you must also specify BindingFlags.Public | BindingFlags.NonPublic to access the private members as well as the public ones. You should double-check that, though 'cause I'm not sure.

The docs state the following:

Since you have neither, I am guessing this is your main problem. The following works for me:

Type t = Type.GetType( "System.String" );            MemberInfo[] info = t.GetMembers( BindingFlags.Instance | BindingFlags.Public );            Console.WriteLine( info.Length );

It seems that the BindingFlags.Public was also necessary.

I was not aware there is a .NET forum... I guess I should start scrolling down on the forum listing. ;)

BindingFlags.Instance | BindingFlags.Public works great, thanks!

Even better, I moved it and left a link in General Programming, so others gradually get to know about it.
