資源簡介

1.在我們開發嵌入式手持機應用時，經常要在Wince手持設備上和上位機之間傳遞數據 2.一般的做法是在上位機部署一個架設在IIS Web服務器上的Webservice服務端 3.這種方案有時候由于實際應用場景里工人的計算機水平有限，客戶需要簡易的實現辦法，要求不要使用遠端Webservice來做數據通訊載體 4.在這種情況下 就使用到了手持機直接訪問上位機SqlServer數據庫服務器的技術 5.本資源文案 演示了如何在.NET 開發平臺上使用C# 簡單快速有效的開發一個基于Wince操作系統手持機的掌上端應用程序 如下載后發現有問題，歡迎和我聯系 Tel:13552251484(電話或者短信) Feiton:822120391 QQ:404993079 Email:baifucn@139.com
