不要使用DataTable，它会产生大量不必要的开销，但可以通过SqlDataReader从SQLServer获取数据 然后，您可以使用我的SqlCeBulkCopy库快速插入SQL Compact数据库。（但可能需要您处理空表） 使用ErikEJ.SqlCe

更多信息和示例应用程序请点击此处：@marc\s感谢您编辑我问题的标题：您只想使用代码或ssms工具进行DDo就可以了you@Vivek我想让它用代码来做。你能给我举个例子吗？@ErikEJ为什么不起作用？我是否必须将我的SqlServerCe引用到4.0才能与EricEJ.SqlCe40匹配？因为我使用的是引用SqlServerCe 3.5而不是4.0？你能给我举个SqlCeBulkCopy的例子吗？我不知道如何使用它。很抱歉问这个问题，我如何才能在我的项目中添加你的“ErikEJ.SqlCeBulkCopy”？我刚下载了你的图书馆。。您的库是否可以在vb.net中使用而不是在c#中使用？如果您使用SQL CE 4.0，它是一个Nuget包，否则只需将项目添加到您的解决方案中，是的，您可以从VBS中调用它。如果包含代码，则必须删除Nuget包！？谢谢你回答我的所有问题我的问题是用ErikEJ.SqlCe.dll解决的我认为这是你的nugget包的旧版本它真的对我有很大帮助：D顺便说一下，我下载了你最新的nugget包2.1.6.15，但当它安装在by project中时，版本说它是2.1.6.14，错误不断出现，所以我想可能会有其他解决方案，即您的旧软件包SqlCeBulkCopy.2.1.6.12.zip再次感谢。。。我现在可以在不到一秒钟的时间内将数据从服务器存储到本地：D
