I am getting an error message like this 'Object reference not set to an instance of an object' when I try to invoke an assembly method dynamically. Please refer to the attached code snippets.
I need forum's help to solve this problem.
The main code snippet.
public partial class Form1 : Form
you are passing "null" as the first parameter to method.Invoke. But the first parameter is the required instance that the method will be executed on. The instance must be an object of the type you loaded dynamically. So before calling invoke you have to create an object from the type "myClassLibrary.myClass". This can be done by reflection also, using the constructor.
do you mean notepad? The windows notepad? This is just an application to edit files. Do you want to store your data within a file? Then think about using a format like csv. How is the linked list connected to this? What do you want to store exactly?
Yessir. The windows notepad. I'll convert it .txt to xml so i can use it to store some data. So when I close my program, if i hit the load button, the data stored in the notepad would come up in the gridbox.
