如何为byte [] yourPhoto分配路径值不接受 [英] How to assign value of path to byte[] yourPhoto it not accept

问题描述

我在Windows表格与2015年工作，我需要更新访问2007中的图像，其中UserID = @ UserID

I work in windows form vs 2015 and i need to update image in access 2007 where UserID=@UserID

 var oleDbConnection = new OleDbConnection(connection);
                    var oleDbCommand = oleDbConnection.CreateCommand();
                    oleDbCommand.CommandText = "Update AllPrinting set  qrimg=@qrimg where UserID=@UserID)";
                    oleDbCommand.Parameters.AddWithValue("@UserID", "UserID");
                    byte[] yourPhoto = path;
                    oleDbCommand.Parameters.AddWithValue("@photo", yourPhoto);
                    using (oleDbConnection)
                    {
                        oleDbConnection.Open();
                        oleDbCommand.ExecuteNonQuery();
                    }

WHEN将路径值分配给 

不接受 

WHEN Assign value of path to 
not accept 

路径变量是字符串，并具有像"d / image";

path variable is string and have the path of image like "d/image";

的图像路径，以便如何分配byte [] yourphoto？

so that how to assign byte[] yourphoto ?
