Linq 與sql方式 添加數據效率比較

所測試環境爲：Ms sqlserver 2008，visual studio 2008

測試數據爲10萬條

 

 Linq方式 代碼：

/// <summary> /// Linq 方式 /// </summary> public static void Linq_insert() { DataClassesDataContext dataContext = new DataClassesDataContext(); for (int i = 0; i < 100000; i++) { Bulletin bulletin = new Bulletin() { ID = 10000 + i, content = "18:00直播亞冠首爾VS山東，敬請期待！！！", date = DateTime.Now, title = "18:00直播亞冠首爾VS山東" }; dataContext.Bulletin.InsertOnSubmit(bulletin); } dataContext.SubmitChanges(); }

 

SQL 方式  代碼：

public static void SQL_insert() { SqlConnectionStringBuilder strB = new SqlConnectionStringBuilder(); strB.DataSource = "."; strB.InitialCatalog = "MyBulltin"; strB.UserID = "sa"; strB.Password = "123"; SqlConnection conn = new SqlConnection(strB.ToString()); SqlCommand comm = null; string sql = "insert into Bulletin(id,content,date,title) values(@id,@content,@date,@title)"; comm = new SqlCommand(sql, conn); conn.Open(); for (int i = 0; i < 100000; i++) { SqlParameter[] param=new SqlParameter[]{ new SqlParameter("@id",i+10000), new SqlParameter("@content","18:00直播亞冠首爾VS山東，敬請期待！！！"), new SqlParameter("@date",DateTime.Now), new SqlParameter("@title","18:00直播亞冠首爾VS山東") }; comm.CommandText = sql; comm.Parameters.AddRange(param); comm.ExecuteNonQuery(); comm.CommandText = string.Empty; comm.Parameters.Clear(); } conn.Close(); }

 

 Main 方法代碼：

DateTime d1 = DateTime.Now; Console.WriteLine("開始:" + d1.ToLocalTime().ToString()); //TestSQL_Linq.Linq_insert(); TestSQL_Linq.SQL_insert(); DateTime d2 = DateTime.Now; Console.WriteLine("結束:" + d2.ToLocalTime().ToString()); Console.WriteLine("共需：" + (d2 - d1));
