im learning how to connect mongoDB with c#

my objective is to import a student.json file and add it to my db in a new collection using c#

this is what im trying to use :

            var command = @"mongoimport --db test --collection colectn2 --file c:\tmp\students.json --jsonArray";

            //get database
            IMongoDatabase testDB = dbClient.GetDatabase("test");

            var result = testDB.RunCommand<BsonDocument>(command);
            Console.WriteLine(result.ToJson());

when i try this in my cmd line works fine.

The problem: mongoimport doesnt import the json file when i try to run it from the c# application but it does import it when i use the same statement from the command line.

Your help is highly appreciate it !
