以二进制形式将图片保存到数据库，用存诸过程实现（完整代码+sql语句）

int intImageSize;
string strImageType;
Stream ImageStream;
//gets the size of the image
intImageSize =this.File1.PostedFile.ContentLength;
//gets the image type
strImageType=this.File1.PostedFile.ContentType;
//reads the image
ImageStream = this.File1.PostedFile.InputStream;

byte [] ImageContent = new byte[intImageSize];
int intStatus;
intStatus=ImageStream.Read(ImageContent,0,intImageSize);
string str=ConfigurationSettings.AppSettings["connString"];
SqlConnection con = new SqlConnection(str);
SqlCommand cmd = new SqlCommand("sp_person_isp",con);
cmd.CommandType=CommandType.StoredProcedure;
//parameters
