如何把圖片保存到SQLServer數(shù)據(jù)庫？

this.pictureBox1.Image=Image.FromStream(this.openFileDialog1.OpenFile());

//獲取當(dāng)前圖片的路徑

stringpath=openFileDialog1.FileName.ToString();

//將制定路徑的圖片添加到FileStream類中

FileStreamfs=newFileStream(path,FileMode.Open,FileAccess.Read);

//通過FileStream對(duì)象實(shí)例化BinaryReader對(duì)象

BinaryReaderbr=newBinaryReader(fs);

//通過BinaryReader類對(duì)象的Readbytes()方法將FileStream類對(duì)象轉(zhuǎn)化為二進(jìn)制數(shù)組

byte[]imgBytesIn=br.ReadBytes(Convert.ToInt32(fs.Length));第二步：

//將圖片添加到數(shù)據(jù)庫中

stringsql="insertintopicvalues(@pic)";

sqlParameter[]param=newSqlParameter[]{newSqlParameter("@pic",imgBytesIn)};

DBHelper.GetExecuteQuery(sql,param);第三步：

//將圖片從數(shù)據(jù)庫中取出

stringsql="select*frompicwhereid=0";

SqlDataReaderreader=DBHelper.GetExecuteReader(sql,null);

MemoryStreammss=null;
