MongoDB C# CRUD (3)

题记：媳妇要求发上来。这篇我要上首页。

1，NuGet引入MongoDB。接着是命名空间

using MongoDB.Bson;
using MongoDB.Driver;
using MongoDB.Driver.Builders;
using MongoDB.Driver.Linq;

2，全局声明

MongoDatabase mongo = new MongoClient(ConfigurationManager.AppSettings["PSConnStrMongoDB"]).GetServer().GetDatabase("psNew");
MongoCollection arts = null;

3，实例化

arts = mongo.GetCollection<ArticleForMongo>("artNew");

4，组织List，批插。过瘾的批插

List<ArticleForMongo> artIns = ai.Select(e => new ArticleForMongo
{
IntArticleID = Convert.ToInt32(e.IntArticleID),
...
IntFree = Convert.ToInt32(e.IntFree)

}).ToList();

//批插
arts.InsertBatch(typeof(ArticleForMongo), artIns);

5，组织ID List，批删

foreach (ArticleList ali in ad)
{
sd.Append(ali.IntArticleID + ",");
}
DeleteArticle(sd.ToString().TrimEnd(','));

批删

List<IMongoQuery> listQuery = new List<IMongoQuery>();
string[] aidList = aid.Split(',');
foreach (string id in aidList)
{
listQuery.Add(Query.EQ("_id", Convert.ToInt32(id)));
}
IMongoQuery query = Query.Or(listQuery);
WriteConcernResult result = arts.Remove(query);
bool bl = result != null && result.Ok;

6，改

public bool UpdateArticle(ArticleForMongo arm)
{
IMongoQuery query;
query = Query.And(Query.EQ("_id", arm.IntArticleID));
BsonDocument bsonDocument = arm.ToBsonDocument<ArticleForMongo>();
bsonDocument.Remove("_id");

var update = new UpdateDocument { { "$set", bsonDocument } };
WriteConcernResult result = arts.Update(query, update);

bool bl = result != null && result.Ok;

//if (bl)
//{
//	Common.AppendTxtFile(opearFilePath, "修改成功 ID：" + arm.IntArticleID);
//}
if (!bl)
{
Common.AppendTxtFile(opearFilePath, "修改失败 ID：" + arm.IntArticleID);
}
return bl;
}

7，查

8，索引

9，性能优化
