Duplicate a mongodb collection

Question

What is a proper way to duplicate a collection in Mongodb on the same server using C#? MongoVUE has an option \'Duplicate collection\', is there something similar for C#?

Answer 1

There isn't a built-in way to copy collections with the C# driver, but you can still do it pretty simply as:

var source = db.GetCollection("test");
var dest = db.GetCollection("testcopy");
dest.InsertBatch(source.FindAll());

Note, however, that this won't copy any indexes from the source collection. The shell's copyTo method has the same limitation so it's likely implemented similarly.
