c# 數據庫的二進制數據 還原成圖片文件

數據來源myAdapter = new SqlDataAdapter(myCmd); 保存到datatable裡面
 
DataTable domainTd = db.returnDataTable(sql, conn) 然後循環datatable
 
數據轉換：byte[] pics1 = (byte[])domainTd.Rows[k]["OldImg"];
 
生成文件代碼：
 
public void writePic(byte[] pics)
{
   FileStream fs = new FileStream(@"E:\123.jpg", FileMode.Append, FileAccess.Write);
   BinaryWriter bw = new BinaryWriter(fs);
   bw.Write(pics, 0, pics.Length);
   bw.Close();
   fs.Close();
}
