IOException reading a large file from a UNC path into a byte array using .NET
- by Matt
I am using the following code to attempt to read a large file (280Mb) into a byte array from a UNC path
public void ReadWholeArray(string fileName, byte[] data)
{
int offset = 0;
int remaining = data.Length;
log.Debug("ReadWholeArray");
FileStream stream = new FileStream(fileName, FileMode.Open, FileAccess.Read);
while (remaining > 0)
{
int read = stream.Read(data, offset, remaining);
if (read <= 0)
throw new EndOfStreamException
(String.Format("End of stream reached with {0} bytes left to read", remaining));
remaining -= read;
offset += read;
}
}
This is blowing up with the following error.
System.IO.IOException: Insufficient system resources exist to complete the requested
If I run this using a local path it works fine, in my test case the UNC path is actually pointing to the local box.
Any thoughts what is going on here ?
