C# MongoDB MongoCollection<；BsonDocument>；。可询问的问题

为什么下面的代码在运行时失败

MongoCollection<BsonDocument> tempCollection = DBHelper.GetInstance().TempCollection();
IList<BsonDocument> documents = (from d in tempCollection.AsQueryable()
                                         where d["Form"].AsString == id
                                         select d).ToList();

MongoCollection tempCollection=DBHelper.GetInstance（）.tempCollection（）；
IList文档=（来自tempCollection.AsQueryable（）中的d）
其中d[“Form”].AsString==id
选择d）.ToList（）；

虽然这很好用

MongoCollection<BsonDocument> tempCollection = DBHelper.GetInstance().TempCollection();
IList<BsonDocument> documents = (from d in tempCollection.FindAll()
                                         where d["Form"].AsString == id
                                         select d).ToList();

MongoCollection tempCollection=DBHelper.GetInstance（）.tempCollection（）；
IList文档=（来自tempCollection.FindAll（）中的d）
其中d[“Form”].AsString==id
选择d）.ToList（）；

“id”是一个字符串类型的参数，用于我的函数，其中包含此代码

我得到以下运行时错误：

任何解释或协助都将不胜感激。 谢谢

编辑： 我修改了代码，将Find方法与MongoQuery结合使用，而不是使用AsQueryable扩展

MongoCollection<BsonDocument> tempCollection = DBHelper.GetInstance().TempCollection();
IList<BsonDocument> documents = tempCollection.Find(Query.EQ("Form",id)).ToList();

MongoCollection tempCollection=DBHelper.GetInstance（）.tempCollection（）；
IList documents=tempCollection.Find（Query.EQ（“Form”，id））.ToList（）；

请格式化您的异常文本，人们可能不会阅读它，因为必须在其中水平滚动非常烦人。
