運(yùn)用到的MongoDB支持的C#驅(qū)動(dòng)，當(dāng)前版本為1.6.0

1,連接數(shù)據(jù)庫(kù)
/// <summary>
/// 數(shù)據(jù)庫(kù)連接
/// </summary>
private const string conn = "mongodb://127.0.0.1:27017";
/// <summary>
/// 指定的數(shù)據(jù)庫(kù)
/// </summary>
private const string dbName = "mongodb_name";
/// <summary>
/// 指定的表
/// </summary>
private const string tbName = "table_text";
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection col = db.GetCollection(tbName);
2、插入數(shù)據(jù)
因?yàn)镸ongoDB沒(méi)有表的概念，所以自插入數(shù)據(jù)之前定義好自己的數(shù)據(jù)模型
User.cs
下面是添加數(shù)據(jù)的代碼
/// <summary>
/// 添加
/// </summary>
/// <param name="text">內(nèi)容</param>
/// <param name="articleId">文章ID</param>
/// <param name="channelId">頻道ID</param>
/// <returns></returns>
public static void Add(User t)
{
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection col = db.GetCollection(tbName);
//插入
col.Insert(t);
}
3、刪除操作
/// <summary>
/// 根據(jù)ObjectID 刪除
/// </summary>
/// <param name="objId"></param>
public static void Delete(string objId)
{
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection<User> col = db.GetCollection<User>(tbName);
IMongoQuery query = Query.EQ("_id", new ObjectId(objId));
col.Remove(query);
}
4、修改
/// <summary>
/// 根據(jù)ObjectID 修改
/// </summary>
public static void Update(User t)
{
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection<User> col = db.GetCollection<User>(tbName);
BsonDocument bd = BsonExtensionMethods.ToBsonDocument(t);
IMongoQuery query = Query.EQ("_id", t.Id);
col.Update(query, new UpdateDocument(bd));
}
5、條件查詢（簡(jiǎn)單）
/// <summary>
/// 根據(jù)ObjectID 查詢
/// </summary>
public static TuCao SelectOne(string objId)
{
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection<User> col = db.GetCollection<User>(tbName);
//條件查詢
return col.FindOne(Query.EQ("_id", new ObjectId(objId)));
}
6、查詢?nèi)?/P> /// <summary>
/// 查詢所有
/// </summary>
public static void SelectAll()
{
List<User> list = new List<User>();
//創(chuàng)建數(shù)據(jù)連接
MongoServer server = MongoServer.Create(conn);
//獲取指定數(shù)據(jù)庫(kù)
MongoDatabase db = server.GetDatabase(dbName);
//獲取表
MongoCollection<User> col = db.GetCollection<User>(tbName);
//查詢?nèi)?BR> list.AddRange(col.FindAll());
//--------------------------------
foreach (TuCao t in col.FindAll())
{
string id = t.Id.ToString();
string text = t.Text;
DateTime dt = t.Createdate;
}
}
