MongoDB查询转对象是出错Element '_id' does not match any field or property of class

MongoDB查询转对象是出错Element ‘_id’ does not match any field or property of class

 

解决方法:

1、在实体类加:[BsonIgnoreExtraElements]

2、或者定义public ObjectId _id { get; set; }

例子:

[BsonIgnoreExtraElements]

public class BaseData
    {
        //public ObjectId _id { get; set; }

        public string cNo { get; set; }

        public string customer { get; set; }

        public long batchNo { get; set; }

        public DateTime mDate { get; set; }

        public string mUser { get; set; }
    }
