Open a file for reading and writing.

The following example opens a file for reading and writing.

C# .NET

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

         // Delete the file if it exists.
         if (!File.Exists(path))
         {
                  // Create the file.
                  FileStream fs = File.Create(path);
                  fs.Close();
         }

         // Open the stream and read it back.
         FileStream fs1 = File.OpenWrite(path);
         Byte[] info = new UTF8Encoding(true).GetBytes("This is to test the OpenWrite method.");
         // Add some information to the file.
         fs1.Write(info, 0, info.Length);
         fs1.Close();

         // Open the stream and read it back.
         FileStream fs2 = File.OpenRead(path);
         byte[] b = new byte[1024];
         UTF8Encoding temp = new UTF8Encoding(true);

         while (fs2.Read(b,0,b.Length) > 0)
         {
                  strRet += (temp.GetString(b) + Environment.NewLine);
         }
         fs2.Close();


         return strRet;
}

Blaze++ .NET

static String DoTest()
{
         String strRet = "";
         String path = "c:\\temp\\MyTestOpenWrite.txt";

         // Delete the file if it exists.
         if (!File::Exists(path))
         {
                  // Create the file.
                  FileStream fs = File::Create(path);
                  fs.Close();
         }

         // Open the stream and read it back.
         FileStream fs1 = File::OpenWrite(path);
         byteA info = UTF8Encoding(true).GetBytes("This is to test the OpenWrite method.");
         // Add some information to the file.
         fs1.Write(info, 0, info.Length);
         fs1.Close();

         // Open the stream and read it back.
         FileStream fs2 = File::OpenRead(path);
         byteA b(1024);
         UTF8Encoding temp(true);
         while (fs2.Read(b,0,b.Length) > 0)
         {
                  strRet += (temp.GetString(b) + Environment::NewLine);
         }
         fs2.Close();


         return strRet;
