How to close a file after creating it

Question

I am coding in C# for the first time and encountering this.

I use the function File.WriteAllBytes(OutputFileName, dest); which is creating a file on the disk and when my application tries to open the same file using file.Open giving me an exception Access to Path Denied. Please help me to get rid of this. I am on Windows 7, not running as administrator.

Thank you.

This probably happens because you don't have permissions to write on that folder. Try to change the path. — dburner, Jan 29 '14 at 09:02

@dburner : The file is getting created. If there is no permission, I think the file will not be created. — NeonGlow, Jan 29 '14 at 09:06
I just wanted to make sure, I am doing it correctly at the code level. — NeonGlow, Jan 29 '14 at 09:16

The file is closed. It is denied for other reasons. Check the path, or maybe you could open it with FileMode File.Open(path, FileMode.Open). Otherwise check your permissions.

Given a byte array and a file path, this method opens the specified file, writes the contents of the byte array to the file, and then closes the file.

I use File.Open(File1Path, FileMode.Open); to try opening the file – NeonGlow Jan 29 '14 at 09:05

The method WriteAllBytes closes the file after writing the byte array to the file so I guess your problem lies elsewhere.

Definition:

Creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

More reading on the method: File.WriteAllBytes Method

Robert was ahead of me.. :)

A couple of things spring to mind:

Where are you saving the file to? Windows 7 seems to picky about saving to the root of C:\ these days.
Permissions issue.
