C#将数据库图片显示在pictureBox

 这里的图片存在数据表的形式为十六进制的数据，参数ds为从数据库中选出的DataSet，字段FImage为图片字段。

private void getPicture(DataSet ds)         {              //int Pictured = dataGridView1.FocusedRowHandle;             int rid=dataGridView1.CurrentRow.Index;             string HasPicture = ds.Tables[0].Rows[rid]["FImage"].ToString();             if (HasPicture !="")               {                  Byte[] byteBLOBData = new Byte[0];                  byteBLOBData = (Byte[])(ds.Tables[0].Rows[rid]["FImage"]);                  MemoryStream stmBLOBData = new MemoryStream(byteBLOBData);                  pictureBox1.Image = Image.FromStream(stmBLOBData);               }                     else                     {                         pictureBox1.Image = null;                     }           }
