MongoDB操作(.net)

一、查询

var doc = new Document();

1、模糊查询
var reg = new MongoRegex(".*" + qry.名称 + ".*", MongoRegexOption.IgnoreCase);
doc["Name"] = reg;

mongodb

{"Name":/CZ/}  不要引号

2、IN查询
var docIn = new Document("$in", qry.名称.Split(','));
doc["Name"] = docIn;

3、等值查询
doc["Name"] = qry.名称;

4、介于时间值之间
Document docLessGreater = new Document();//参数
doc.Insert("$gte", startTime, 0);//大于开始时间
doc.Insert("$lte", endTime, 1);//小于结束时间
doc["CollectTime"] = docLessGreater;

 

5.Or查询

   var docInT = new Document();
                docInT["Type"] = new MongoRegex(".*" + "A" + ".*", MongoRegexOption.None);

                var docInT2 = new Document();
                docInT2["Type"] = new MongoRegex(".*" + "B" + ".*", MongoRegexOption.None);

                List<Document> lst = new List<Document>();
                lst.Add(docInT);
                lst.Add(docInT2);
                doc["$or"] = lst;
