推荐答案

你在这里做的是跨数据库。如果您只是谷歌，您应该了解如何使用您正在使用的任何提供商。我建议您在这种情况下使用存储过程生成行，因为您无法控制跨数据库参照完整性。



如果您不想这样做而你只是想通过C＃来实现它，你只需从你需要的每个数据库中提取数据然后插入到任何数据库中。



如果你正在寻找关于如何使用ADO.NET或EF，那么你需要自己做研究。

What you're doing here is cross-database. If you just Google that you should find out how to do it with whatever provider you're using. I recommend that you use stored procedures to generate rows in that case because you can't control cross-database referential integrity.

If you don't want to do that and you're just going to do it through C#, you simply pull the data down from each database you need then insert into whichever database.

If you're looking for how to use ADO.NET or EF, then you need to do research on those yourself.
