示例1: BsonDocMethod

{
var doc = new BsonDocument
{
{"name", "Sanya" }
};
doc.Add("age", 30);
doc["profession"] = "hacker";
var nestedArray = new BsonArray();
nestedArray.Add(new BsonDocument("color", "red"));

Console.WriteLine(1);
//Console.WriteLine(doc.TryGetElement("name", out name));
Console.WriteLine(doc.Count());
Console.WriteLine();
Console.WriteLine(doc.ContainsValue("Sanya"));
Console.WriteLine(doc.Contains("name"));

//var doc2 = new BsonDocument
//{
// { "Name", "Smith"},
// {"Something", "something else" },
// {"profession", "hacker" }
//};
//await collectionUsed.InsertManyAsync(new[] { doc, doc2 });
}示例2: GetAggregation
/// <summary>
/// Aggregation用的$project和$order
/// </summary>
/// <returns></returns>
public List<BsonDocument> GetAggregation()
{
//如果有改名的话，则其他没有改名的，也需要设定输出

//没有改名和抑制的时候，则project全部去除
