{ 
    "_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总是0.我做错了什么？

谢谢
