var document = new BsonDocument{{ "$where","this.StarTime!=this.EndTime"},{ "Closed",1},{ "StarTime",new BsonDocument("$gte",request.Stime)},{ "EndTime",new BsonDocument("$lte",request.Etime)},{ "TotalSecond",new BsonDocument(para,request.TotalMin * 60)}};var list= collection.Find(document);

其中this不能省略，写法同mongodb命令，使用此写法可以自由拼接参数

 

//判断时间范围，单位：秒

var document = new BsonDocument{{ "$where","this.StarTime-this.EndTime>10"},{ "Closed",1},{ "StarTime",new BsonDocument("$gte",request.Stime)},{ "EndTime",new BsonDocument("$lte",request.Etime)},{ "TotalSecond",new BsonDocument(para,request.TotalMin * 60)}};var list= collection.Find(document);
