Dynamically loading a dll and invoking a method in it

Language: C#

Source Code:

// Adding assembly referenece dynamically

Assembly addassembly = Assembly.LoadFrom(<path>);

foreach (Type type in addassembly.GetTypes())


// If it is class it will go into the “if” structure

if (type.IsClass == true)


// the class must have extended an interface which has the method name that you want to invoke, this ensures the presence of the method that you want to invoke in the

if (type.GetInterface(<Inteface_name>) == null)




object obj = Activator.CreateInstance(type);

// Invokes the method

object result = type.InvokeMember(<method_name>, BindingFlags.InvokeMethod | BindingFlags.Default, null, obj, null);
