如何使用 C# 驱动程序将 BsonArray 添加到 MongoDB 中的 BsonDocument？我想要这样的结果

{ 
    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' }
    ]
}

How can I add BsonArray to BsonDocument in MongoDB using a C# driver? I want a result something like this

{ 
    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' }
    ]
}

您可以使用以下语句在 C# 中创建上述文档：

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" } }
    }}
};

您可以使用以下命令测试是否产生了正确的结果：

var json = document.ToJson();

You can create the above document in C# with the following statement:

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" } }
    }}
};

You can test whether you produced the correct result with:

var json = document.ToJson();

您还可以在 BsonDocument 已经存在之后添加数组，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);

you can also add the array after the BsonDocument already exists, like this:

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);
