我可以使用 Sql Server CE (3.0) 作为 Windows 应用程序的嵌入式数据库吗？我必须在机器上安装 Sql Server CE 吗？
我创建了一个 Windows 应用程序，并且需要一个数据库。我首先在其中使用SQL Server Express 版本。然后我才知道它不完全是一个可移植数据库。也就是说，SQL Server Express 版本应该已经安装在我打算使用我的应用程序的计算机上。我发现我可以使用 SQL CE 来代替并更改为它。我发现我所要做的就是将 sqlceme30.dll 复制到应用程序中。在我的开发系统中运行良好。但是，当我将应用程序复制到另一个系统并打开该应用程序时，它会抛出错误
System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
Can I use SQL CE in my application?我真的不想将它安装在我使用我的应用程序的所有机器上。或者如果没有，我可以使用哪些其他数据库而无需安装？使用权？
I created a windows application and I needed a database for it. I first used SQL Server Express edition in it. Then I came to know that it is not exactly a portable database. That is, SQL Server Express edition should be already installed in the computer where I suppose to use my application. I came to know that I can use SQL CE instead and changed to it. I found somewhere that all I have to do is just copy the sqlceme30.dll in the application. Worked fine in my developement system. But when I copy the application to another system and open the application, it throws the error
System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.SqlServerCe, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
Can I use SQL CE in my application? I really don't want to install it in all the machines I use my app. Or if not, which other db I can use without intalling? Access?

确保您的引用设置为
复制本地。右键单击引用，然后单击属性。他们将Copy Local属性更改为true。这将确保 dll 包含在发布中。Ensure your reference is set to
Copy Local. Right click on the reference, and click properties. They change theCopy Localproperty totrue. That will ensure that the dll is included in the publish.
