Bagaimana cara memeriksa apakah koleksi ada di MongoDB menggunakan driver C #?

@im1dermike answer tidak lagi berfungsi untuk driver c# versi 2.0+

Ini alternatifnya:

    public async Task<bool> CollectionExistsAsync(string collectionName)
    {
        var filter = new BsonDocument("name", collectionName);
        //filter by collection name
        var collections = await GetDatabase().ListCollectionsAsync(new ListCollectionsOptions { Filter = filter });
        //check for existence
        return await collections.AnyAsync();
    }
