如何重命名mongodb数据库 [英] How rename a mongodb database

问题描述

我需要以编程方式重命名MongoDB DB数据库.我没有看到使用MongoDB c#驱动程序执行此操作的方法.

I need to rename a MongoDB DB database programmatically. I have not seen a way to do this with the MongoDB c# driver.

我想做类似的事情:this.mongoClient.renameDatabase("oldName"，"newName");

I would like to do something like: this.mongoClient.renameDatabase("oldName","newName");

我认为我可以自己动手，但我认为使用当前的驱动程序应该可以实现.

I figure I can roll my own but I feel like this should be possible with a current driver.

推荐答案

在admin数据库上为源db中每个集合名称运行一个 renameCollection 命令，格式为:

run a renameCollection command on the admin database for every collection name in your source db with the format:

renameCollection:'old.CollectionName'，至:'new.CollectionName'

这是在c#中执行的方法:

here's how to do it in c#:

var client = new MongoClient();
var dbAdmin = client.GetDatabase("admin");

var dbOldName = "old-db";
var dbNewName = "new-db";

var collections = client.GetDatabase(dbOldName).ListCollectionNames().ToList();

foreach (var collection in collections)
{
    var command = $"{{ renameCollection: '{dbOldName}.{collection}', to: '{dbNewName}.{collection}' }}";

    dbAdmin.RunCommand<BsonDocument>(command);
}
