Convert string into MongoDB BsonDocument

问题:

I have a long string in JSON format, and I want to convert it into a BSONDocument for insertion into a MongoDB database. How do I do the conversion? I'm using the official C# driver.

回答1:

The answer is:

string json = "{ 'foo' : 'bar' }";
MongoDB.Bson.BsonDocument document
    = MongoDB.Bson.Serialization.BsonSerializer.Deserialize<BsonDocument>(json);

回答2:

string json = "{ 'foo' : 'bar' }";  
BsonDocument document = BsonDocument.Parse(json);

回答3:

Using Version 2.1 of MongoDB's .NET library

string json = "{'foo' : 'bar' }";
var document = new BsonDocument();
document.Add(BsonDocument.Parse(json));
