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; }
}
