.NET File Stream write method writes all empty lines

Question

I am having a C# console application access files over a network and write to it. I noticed that some files have been corrupted and have only null written to them. I did not get any exceptions. I am using simple code that writes a byte array to the file's stream. When opening the files in Binary mode, all i see are Zeros, something like "0: 00 00 00 00 10: 00 00 00 00".

Does anyone know why such a thing would happen? There could have been a network failure, but network failures should have thrown some IO exceptions right?

Let me know if anyone has any idea about this.

Code sample:

FileInfo fi = new FileInfo(filePath);
using (FileStream fs = fi.Open (FileMode.Create, FileAccess.Write, FileShare.None))
{
   fs.Write(byteData, 0, byteData.Length);
}

Answer 1

Make sure to call FileStream.Flush() where appropriate.

Answer 2

Make sure you're closing the file.
