Help! A C# problem

Question

I made a text reader by C# to monitor log files.But when I tried to read a log file which had been opened by another application,a error occured.It sounds like the application has occupied the file,so I can't read it.However,when I use UltraEdit or Windows notepad to do the same thing,no error occur. Why UltraEdit can,but I can't.Please help me!Thank you!

I use a RichTextBox to display the content of log.The code is: try{ RichTextBox.LoadFile(pathRichTextBoxStreamType.PlainText); } How to control the access permission you said.Thank you!

What lines of code are you using? It may be because the FileStream object you instantiate is trying to get more than read only access when another program has locked down the file for read/write access.
