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);
