Answer 1

The end of a Stream is reached when a Stream.Read returns zero.

An example from MSDN, FileStream:

// Open a stream and read it back.
using (FileStream fs = File.OpenRead(path))
{
    byte[] b = new byte[1024];
    UTF8Encoding temp = new UTF8Encoding(true);
    while (fs.Read(b,0,b.Length) > 0)
    {
        Console.WriteLine(temp.GetString(b));
    }
}

or,

using (StreamReader sr = File.OpenText(filepath))
{
     string line;
     while ((line = sr.ReadLine()) != null)
     {
          // Do something with line...
          lineCount++;
     }
}

Answer 2

Maybe what you are looking for is this

using (StreamReader sr = new StreamReader("TestFile.txt"))
{
    String line;
    while ((line = sr.ReadLine()) != null)
    {
         Console.WriteLine(line);
    }
}

Answer 3

There is no "end of file character" in a string (or even in a file). The length of the string is known (Length property), so it's not necessary

When reading a file, you can check :

• if Stream.Read returns 0
• if StreamReader.ReadLine returns null

Answer 4

There is no EOF character. Call FileStream.Read in a loop. When .Read() returns 0 for no bytes read, you're done.

Answer 5

There's no such character. If you call FileStream.ReadByte, it will return -1 for end-of-file. The Read method return zero bytes read. If you use a StreamReader around the stream, its ReadLine method returns null or its EndOfStream property returns true.
