C#文件和字节流的转换方法

FileStream fs = new FileStream(filename,FileMode.Open,FileAccess.Read);byte[] infbytes = new byte[(int)fs.Length];fs.Read(infbytes, 0, infbytes.Length);fs.Close();return infbytes;

FileStream fs = new FileStream("D:/inf.dlv",FileMode.Create,FileAccess.Write);fs.Write(infbytes, 0, inf.Length);fs.Close();
