I am reading bytes from a data file using the ReadByte() method, but I am having some trouble finding out when the end of the data file has been reached. What I do now seems like a lot of work.

string sFileName = "C:\\NMCC\\MWD\\data20041203134748.mwd";

// Read the file using the stream reader to get the length of the file
System.IO.StreamReader oReader = System.IO.File.OpenText(sFileName);
string lcString = oReader.ReadToEnd();
oReader.Close();

// Use the length to the string to determine size of byte[]
System.Byte[] myByte = new System.Byte[lcString.Length];
System.IO.FileStream fs = new System.IO.FileStream(sFileName,System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.BinaryReader r = new System.IO.BinaryReader(fs);

// ReadByte() in a for loop
for (int i = 0 ; i < lcString.Length; i++)
{
	myByte[i] = r.ReadByte();
}

I know I can use the ReadBytes() method to get rid of the for loop but I would still need a way to find out how many bytes to read.

What would be nice is if I can use a while loop around the ReadByte() method, but the ReadByte() method returns a System.Byte and I can't find anything to test for to check if I have reached the end.

I can catch the an exception that the ReadByte() throws if the method is executed after EOF is reached.

Any help would be appreciated.

Thanks,
Einar
