c#.NET file acces denied problem

Filed under: C#.NET, Side Notes — Tags: , — admin @ 4:03 pm

I was trying to access a file with the user having only read permission. the code looked like:

FileStream fs =new FileStream(
"c:\path\to\file.ext",
FileMode.Open);

and it uset to throw exception “access denied”. After some investigations I’ve found that FileAccess.Read helps a lot.

FileStream fs = new FileStream(
"c:\path\to\file.ext",
FileMode.Open,
FileAccess.Read);
