MongoDB c＃创建角色？

Question

我试图用c＃驱动程序创建一个角色。 谁能告诉我怎么做？

我尝试了几样这样的事情：

var command = new CommandDocument( 
                new BsonDocument
                {
                    { "createRole", "Testentity_read" },
                    { "privileges", new BsonArray(new BsonDocument
                        {
                            {
                                "resource", new BsonDocument
                                {
                                    {"db", "MyDb"},
                                    {"collection", "Testentity"}
                                }
                            },
                            {
                                "actions", new BsonArray {"read"}
                            }
                        })},
                    { "roles", new BsonArray()}
                }
            );

            var result = _database.RunCommand(command);

但总是得到这个例外：

".NET type MongoDB.Bson.BsonElement cannot be mapped to a BsonValue."

我发现了如何使用C＃-driver创建一个角色。

var command = new CommandDocument
{
    {
        "createRole", "Testentity_find"
    },
    { 
        "privileges", new BsonArray
        {
            new BsonDocument
            {
                {
                   "resource", new BsonDocument
                    {
                        {"db", "MyDb"},
                        {"collection", "Testentity"}
                    }
                },
                {

                    "actions", new BsonArray {"find"}
                }
            }
        }
    },
    { "roles", new BsonArray()}
};
