实时更新Winforms中的文本字段消息

Question

I have a service that add items to a class and then serialize a class into a file.

Then I need to create a simple form C# with a textfield (multiline) showing realtime from the deserialized file.

I will have timer every second that will read my List of a property of the class and show it in a textfield.

My question here is:

Is there a way that instead of reading again and again the file I can just get the latest rows added and just append to the textfield?

Answer 1

var file = File.OpenRead("abc.txt");
file.Seek(1000, SeekOrigin.Begin);

Reading a file, use "Seek" to skip old data.

Answer 2

just a suggestion:

I think, you should rather use some sort of message queue for this purpose.

Again per your post, instead of directly fetching from file, it would be good if you rather store the deserialized content in a stack . That way, you can always get the content from top of the stack.
