问题描述

I want to display a large *.txt file to RichTextBox. The size is about 7MB.
When I use RichTextBox.LoadFile() method, it takes a long time(about 2 minutes) util it shown up. 
But if I use wordpad or any other free editors, it displayed very soon.
How can I improve the performance?
Please give me some advice.
 
The code is:
RichTextBox1.LoadFile(FilePath, RichTextBoxStreamType.RichText);
