MongoDB:获取所有数据库的列表？

Question

如何使用Mongo C#Driver列出连接的所有数据库？

Answer 1

非常简单地:

var server = MongoServer.Create("mongodb://localhost/?safe=true");
var databaseNames = server.GetDatabaseNames();

Answer 2

在2.0.0版中不推荐使用MongoServer类.

您可以使用ListDatabasesAsync

using (var cursor = await client.ListDatabasesAsync())
{
    await cursor.ForEachAsync(d => Console.WriteLine(d.ToString()));
}

Answer 3

工作解决方案：

MongoClient client = new MongoClient("mongodb://localhost:27017");
using (IAsyncCursor<BsonDocument> cursor = client.ListDatabases())
{
    while (cursor.MoveNext())
    {
        foreach (var doc in cursor.Current)
        {
            Console.WriteLine(doc["name"]); // database name
        }
    }
}
