将图片文件以byte的形式从导数据库中

byte[] FileByteArray = new byte[FileLength];  //图象文件临时储存Byte数组

               
//Stream StreamObject =
UpFile.InputStream;            
//建立数据流对像

/////读取图象文件数据，FileByteArray为数据储存体，0为数据指针位置、FileLnegth为数据长度  

               
//StreamObject.Read(FileByteArray, 0,
FileLength);
               
//StreamObject =
null;
               
FileStream fs = new FileStream(FullFilePath,
FileMode.OpenOrCreate);
               
BinaryReader rs = new
BinaryReader(fs);
               
FileByteArray =
rs.ReadBytes(Convert.ToInt32(fs.Length));
               
rs.Close();
               
rs =
null;
               
fs.Close();
               
fs = null;

theNewFile.CONTENT = FileByteArray;
