MongoDB commands from DOS or Windows
提问by iefpw
I'm trying to copy 4 collections from one Mongo database to another on the same machine from C# program automatically. How do I do that? Is there a simple copy collection/database command in MongoDB C# driver? or do I have to use the Mongo shell by first typing the ./mongo? If so how do I do that inside a MS-DOS command line window? Like ./mongo -copycollection from to?
我正在尝试从 C# 程序自动将 4 个集合从一个 Mongo 数据库复制到同一台机器上的另一个数据库。我怎么做？MongoDB C# 驱动程序中是否有简单的副本收集/数据库命令？还是我必须先输入./mongo? 如果是这样，我如何在 MS-DOS 命令行窗口中执行此操作？喜欢./mongo -copycollection from to？
