Hello,
i have made app that opens file with OpenFileDialog and writes a value into file. But it deletes all hex values in file.

BinaryWriter bw = new BinaryWriter bw = new BinaryWriter(File.OpenWrite(ofd.FileName));
            Byte[] Bytes = { 0x46, 0x46, 0x44 };
            bw.BaseStream.Position = (0x0106E);
bw.Write(Bytes);
bw.Flush();
bw.Close

Everything is deleted from file and only 464644 are in their possition and that ends file.
What i am doing wrong and how to do this right?
Thanks in advance.

You are WRITING a file instead of APPENDING to the file.


See where you set it to File.OpenWrite instead of Apend on line 1?

BinaryWriter bw = new BinaryWriter(File.Open(ofd.FileName, FileMode.Open, FileAccess.ReadWrite));
