SmartDevice項目中缺少Data.SqlClient命名空間（Windows Mobile）

Question

我開始在Windows Mobile 6.5上編程。 我安裝了VS2008，SDK 6.0和DTK 6.5.3。創建項目（WM 6.0，.NET 3.5），並且不使用System.Data.SqlClient。我只有System.Data是Common，SqlTypes。 參考文獻被創作者包含在內。

SqlCommand comm = new SqlCommand（sSQL，new SqlConnection（sConn））; 無法解析符號'SqlCommand'

我錯過了什麼嗎？如何從設備連接Sql Server？互聯網上的許多例子包括這種方法。

我還安裝了.NET 4.0，4.5和VS 2012

Answer 1

雖然我不知道TDK是什麼，你需要下載並安裝SQL Server CE /緊湊分開拿到SQLClientCE等對象：

Windows Desktop

Windows Mobile

FOR WINDOWS MOBILE USE INSTALL THE LINOND DOWNLOAD DOWNLOAD！

請注意，Windos Mobile 6.5應用程序無法使用.NET 4或VS 2012或VS 2010開發.Windows Mobile/Embeddded Handheld Programming僅支持到VS 2008！

在安裝Sql Server Compact for Mobile之後，您將有一個新程序目錄「C：\ Program Files（x86）\ Microsoft SQL Server Compact Edition \ v3.5」（另請參閱附件slq_server_compact35_files.txt）。現在

，你開始了一個新SmartDevice項目或打開一個現有的後，您必須添加引用要麼System.Data.SqlClient的或System.Data.SqlServerCE：
