hi friends,

what mean this code?

MIDL

byte[] fileNameByte = Encoding.ASCII.GetBytes(fileName);

byte[] fileData = File.ReadAllBytes(filePath + fileName);

byte[] Data = new byte[4 + fileNameByte.Length + fileData.Length];

byte[] fileNameLen = BitConverter.GetBytes(fileNameByte.Length);

fileNameLen.CopyTo(Data, 0);
fileNameByte.CopyTo(Data, 4);
fileData.CopyTo(Data, 4 + fileNameByte.Length);

specifically this code

MIDL

fileNameLen.CopyTo(Data, 0);
           fileNameByte.CopyTo(Data, 4);
           fileData.CopyTo(Data, 4 + fileNameByte.Length);

thank you

I agree, we are here to share the knowledge, not to insult other.

What do you consider insulting? My vote of 1? Please...
By the way, account of xxxxxxxy is now disabled. Guess why?

This code please
=====================
fileNameLen.CopyTo(Data, 0);
fileNameByte.CopyTo(Data, 4);
fileData.CopyTo(Data, 4 + fileNameByte.Length);

Better accept both answers formally. You already gave code. By the way, how come you present the code you don't understand? You're suppose to write code instead, as this resource if for developers :-)
