Answer 1

Use a file stream.

You can save a lot of different data_types in there. This example uses. Memorystream.

private void button1_Click(object sender, EventArgs e)
{
string memString = "Memory test string !!";
// convert string to stream
byte[] buffer = Encoding.ASCII.GetBytes(memString);
MemoryStream ms = new MemoryStream(buffer);
//write to file
FileStream file = new FileStream("d:\\file.txt", FileMode.Create, FileAccess.Write);
ms.WriteTo(file);
file.Close();
ms.Close();
}
