Adding BSON array to BsonDocument in MongoDB
How can I add Bs开发者_JAVA技巧onArray 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' }
]
}
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();
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);
