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
     
      ("artNew");
     

 4，组织List，批插。过瘾的批插

List
     
       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
     
       listQuery = new List
      
       ();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
     
      ();			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
