我有一个以下格式的MongoDB集合:

{ 
    "_id" : ObjectId("5692a3397d7518330416f8e5"), 
    "supertagname" : "xxx", 
    "inclusions" : [
        "test", 
        "blabla"
    ], 
    "exclusions" : [ ]
}

我试图查询数组"包含"包含我正在寻找的值的所有文档.这是代码

string t = "blabla"; // the string value I am looking for

filter = Builders<BsonDocument>.Filter.ElemMatch(
    "inclusions", Builders<BsonDocument>.Filter.Eq("inclusions", t));

var matches = dictCollection.Find(filter).ToList();

foreach (BsonDocument doc in matches) {}

matches.count 永远是0.我做错了什么？

谢谢
