InsertMany Document in a MongoDB Collection using C# BsonArray

Question

How to Insert more than one document in a Single statement using InsertMany() MongoDB Method in C#

My MongoDB Database and Connections

IMongoClient _client;
IMongoDatabase _database;

_client = new MongoClient();
_database = _client.GetDatabase("test");

var collection = _database.GetCollection<BsonDocument>("EmpInfo");

I'm having a Collection - BsonArray

var EmpInfoArray = new BsonArray {
    new BsonDocument
    {
        {"EmpID", "100"},
        {"EmpName", "John"},
        {"EmpMobile", new BsonArray
                        {
                            new BsonDocument { 
                                {"MobNumber", "55566610"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", false}
                            },
                            new BsonDocument { 
                                {"MobNumber", "55566611"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", true} 
                            },
                        }
        },
        {"IsLive", true}
    },

    new BsonDocument
    {
        {"EmpID", "101"},
        {"EmpName", "Peter"},
        {"EmpMobile", new BsonArray
                        {
                            new BsonDocument { 
                                {"MobNumber", "55566610"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", false}
                            },
                            new BsonDocument { 
                                {"MobNumber", "55566611"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", false} 
                            },
                        }
        },
        {"IsLive", true}
    },

    new BsonDocument
    {
        {"EmpID", "102"},
        {"EmpName", "Jack"},
        {"EmpMobile", new BsonArray
                        {
                            new BsonDocument { 
                                {"MobNumber", "55566610"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", true}
                            },
                            new BsonDocument { 
                                {"MobNumber", "55566611"}, 
                                {"IsPreferred", true}, 
                                {"IsLive", true} 
                            },
                        }
        },
        {"IsLive", false}
    }

}

The Insert Statement:

collection.InsertMany(EmpInfoArray);

In the above InsertMany() Extended method has a build error . Kindly assist me how to insert multiple records in a single statement execution using C#.

Answer 1

Off the top of my head, the build error is most probably because the InsertMany method is expecting a collection ( IEnumerable , List or Array ..) of BsonDocument instead of a BsonArray .

try :

var EmpInfoArray = new List<BsonDocument>() { //Changed BsonArray to List<BsonDocument>
    new BsonDocument
    {
        {"EmpID", "100"},
        {"EmpName", "John"},
        {"EmpMobile", new BsonArray
        .
        .
        .
