Read five characters at a time until the end of the file is reached.

The following example reads five characters at a time until the end of the file is reached.

C# .NET

public static String DoTest()
{
         string strRet = "";
         string path = @"c:\temp\MyTestRead.txt";

         try
         {
                  if (File.Exists(path))
                  {
                           File.Delete(path);
                  }

                  StreamWriter sw = new StreamWriter(path);
                  sw.WriteLine("This");
                  sw.WriteLine("is some text");
                  sw.WriteLine("to test");
                  sw.WriteLine("Read method");
                  sw.Flush();
                  sw.Close();

                  StreamReader sr = new StreamReader(path);
                  //This is an arbitrary size for this example.
                  char[] c = null;
                  while (sr.Peek() >= 0)
                  {

                           sr.Read(c, 0, c.Length);
                           //The output will look odd, because
                           //only five characters are read at a time.
                           StringBuilder sb = new StringBuilder();
