在MongoDB中添加BSON數組到BsonDocument

Question

如何使用C＃驅動程序將BsonArray添加到MongoDB中的BsonDocument？我想結果是這樣的

{ 
    author: 'joe', 
    title : 'Yet another blog post', 
    text : 'Here is the text...', 
    tags : [ 'example', 'joe' ], 
    comments : [ { author: 'jim', comment: 'I disagree' }, 
       { author: 'nancy', comment: 'Good post' } 
    ] 
} 

Answer 1

您可以用下面的語句創建C＃中的上述文件：

var document = new BsonDocument { 
    { "author", "joe" }, 
    { "title", "yet another blog post" }, 
    { "text", "here is the text..." }, 
    { "tags", new BsonArray { "example", "joe" } }, 
    { "comments", new BsonArray { 
     new BsonDocument { { "author", "jim" }, { "comment", "I disagree" } }, 
     new BsonDocument { { "author", "nancy" }, { "comment", "Good post" } } 
    }} 
}; 

您可以測試你是否有與寫結果：

var json = document.ToJson(); 

Answer 2

您還可以在BsonDocument已經存在之後添加陣列，如下所示：

BsonDocument doc = new BsonDocument { 
    { "author", "joe" }, 
     { "title", "yet another blog post" }, 
    { "text", "here is the text..." } 
}; 

BsonArray array1 = new BsonArray { 
     "example", "joe" 
    }; 


BsonArray array2 = new BsonArray { 
     new BsonDocument { { "author", "jim" }, { "comment", "I disagree" } }, 
     new BsonDocument { { "author", "nancy" }, { "comment", "Good post" } } 
    }; 


doc.Add("tags", array1); 
doc.Add("comments", array2);
