MongoDb c＃将文档转换为对象

Question

我想通过筛选器获取文档列表，该筛选器返回具有categoryId = 1的帖子。我不知道如何使这项工作：

public List<Post> getAllProgramming() 
    { 
     var result = new List<Post>(); 

     var mongoClient = new MongoClient("mongodb://localhost"); 
     var database = mongoClient.GetDatabase("SearchForKnowledge"); 
     var coll = database.GetCollection<BsonDocument>("Posts"); 

     var filter = Builders<BsonDocument>.Filter.Eq("CategoryId", 1); 
     result = coll.Find(filter).ToList<Post>; 
    } 

一切都很好，除了最后一行代码，转换无效。应该怎样解决这个问题？提前谢谢你，祝你有愉快的星期五！

您可以尝试如下...

public List<Post> getAllProgramming() 
{ 
    var result = new List<Post>(); 

    var mongoClient = new MongoClient("mongodb://localhost"); 
    var database = mongoClient.GetDatabase("SearchForKnowledge"); 
    var coll = database.GetCollection<Post>("Posts"); 

    var filter = Builders<Post>.Filter.Eq(p => p.CategoryId, 1); 
    result = coll.Find(filter).ToList(); 
}
