public class Main {
public Type GetTypeOfGenericArg(Type derivedClassType) {
var typedMyInterfaceType = derivedClassType.GetInterface(typeof(MyInterface<>).FullName);
// If derivedClassType is 'MyFoo', typedMyInterfaceType is typeof(MyInterface<Foo>)
return typedMyInterfaceType.GetGenericArguments()[0];
public Type GetTypeOfGenericArgByPropertyName(Type derivedClassType) {
var myParamPropertyInfo = derivedClassType.GetProperty(nameof(MyInterface.MyParameter));
