Question

I am in the process of converting some C++ code to C#, I am trying to figure out how I could write out and following C++ code in my C# app and have it do the same thing:

fread(&Start, 1, 4, ReadMunge); //Read File position

I have tried multiple ways such as using FileStream:

        using (FileStream fs = File.OpenRead("File-0027.AFS"))
        {
            //Read amount of files from offset 4
            fs.Seek(4, SeekOrigin.Begin);
            FileAmount = fs.ReadByte();
            string strNumber = Convert.ToString(FileAmount);
            fileamountStatus.Text = strNumber;

            //Seek to beginning of LBA table
            fs.Seek(8, SeekOrigin.Begin);
            CurrentOffset = fs.Position;

            int numBytesRead = 0;

            while (Loop < FileAmount) //We want this to loop till it reachs our FileAmount number
            {
                Loop = Loop + 1;

                //fread(&Start, 1, 4, ReadMunge); //Read File position
                //Start = fs.ReadByte();
                //Size = fs.ReadByte();
                CurrentOffset = fs.Position;
                int CurrentOffsetINT = unchecked((int)CurrentOffset);

                //Start = fs.Read(bytes,0, 4);
                Start = fs.Read(bytes, CurrentOffsetINT, 4);
                Size = fs.Read(bytes, CurrentOffsetINT, 4);


                Start = fs.ReadByte();


            }
        }

The problem I keep running into is that Start/Size do not hold the 4 bytes of data that I need.

If you’re reading a binary file, you probably should look into using BinaryReader. That way you don’t have to worry about converting byte arrays to integers or whatever. You can simply call reader.ReadInt32, for example, to read an int.
