Welcome to the MongoDB Community. I understand that you’re having trouble querying a document by the value in an array element. I wrote the following minimal repro and was able to successfully query documents from a collection with a similar structure:
var client = new MongoClient();
var db = client.GetDatabase("test");
var coll = db.GetCollection<BsonDocument>("coll");
var filter = Builders<BsonDocument>.Filter.Eq("Parameters.Value", 11111);
var query = coll.Find(filter);
foreach (var result in query.ToList())
Note that your C# filter contains the value
"11111" (data type is
string) but your schema appears to contain values in the array of type
int. In my filter above, I use the numeric value
11111 to query matching documents.
When querying data from MongoDB, you must either use the correct data types in your query or explicitly convert values to a common data type prior to comparison.
If you continue to have problems with this query, please provide a self-contained repro as well as sample data so we can troubleshoot further.
