问知道DLL中存在哪些类和方法的不同方法是什么？

EN

var assembly = ...; // e.g. typeof(SomeType).Assembly
var types = assembly.GetTypes();
var methods = types.SelectMany(type => type.GetMethods());
// etc

public IEnumerable<Type> GetAllTypesInDll(string filename)
{
    // load assembly from file
    Assembly asm = Assembly.LoadFile(filename);

    // enumerate all types
    return asm.GetTypes();
}

foreach (Type type in from e in GetAllTypesInDll(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Console.exe"))
                      orderby e.FullName
                      select e)
{
    // print type
    Console.WriteLine("----------------");
    Console.WriteLine(type.FullName);

    // print type methods
    Console.WriteLine("Methods:");
    foreach (var mi in from e in type.GetMethods()
                       orderby e.Name
                       select e)
    {
        Console.WriteLine("    " + mi.Name);
    }
    Console.WriteLine("----------------");
}
