How to retrieve all public methods from *.dll

Question

I have *.dll written with C# and I need to get list of all public methods or classes contained in that *.dll. Is there some way to do it programmatically with C#?

Answer 1

Use System.Net.Reflection. Reflection classes let you query the metadata of types of a DLL at run time.

Something like this.GetType().Assembly.GetTypes();

Answer 2

Yes use Assembly.GetTypes to extract all of the types, and then use reflection on each type to iterate the public methods.

Assembly a = Assembly.LoadWithPartialName("...");
Type[] types = a.GetTypes();
foreach (Type type in types)
{
    if (!type.IsPublic)
    {
        continue;
    }

    MemberInfo[] members = type.GetMembers(BindingFlags.Public
                                          |BindingFlags.Instance
                                          |BindingFlags.InvokeMethod);
    foreach (MemberInfo member in members)
    {
        Console.WriteLine(type.Name+"."+member.Name);
    }
}

Answer 3

var assembly = // grab assembly
var types = assembly.GetExportedTypes();

foreach (var type in types) {
    var methods = type.GetMethods(BindingFlags.Public);
}

GetExportedTypes will return all public types in the assembly. You also didn't specify whether you wanted just instance methods, static methods or both.
