c# Mongodb两个字段不相等 MongoDB原生查询

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