IIS 發布專案可以打包成 zip, 之後直接用匯入的, 還不錯用. 

Server 端要安裝兩個東西. 順序不可以錯, 錯了就要移除重新安裝.

1. IIS 的 Management Service 



2. Web Deploy v3.6

在專案結案前跑一下, 還不錯用.

UW -> DB 物件產生器會產生兩個function
GetAllDataFromBaseTableWithCache(string OrderFields = "_Default", bool IsCopy = true )
以及
Get物件名稱FromCachedDT(string Key)
-----------------------------------------------------------
設計上是希望將所有資料Cache在記憶體，然後前端直接抓出資料，不須到資料庫抓資料
理論上網頁速度應該比較佳，實際上卻發現是效能殺手

原因在於 GetAllDataFromBaseTableWithCache 是抓出整個table的資料放到 Cache
然後又做了一件事，當有人要資料時，會把整個 DataTable 做 Copy() 再 return
也就是說，當DataTable有數千筆資料列時
每叫用一次 "Get物件名稱FromCachedDT(string Key)" 就會把數千筆資料整個複製一次
再從複製出來的DataTable Select 出一列 return
------------------------------------------------------------
解決方法:
Get物件名稱FromCachedDT(string Key)  --> 改成一筆一筆資料做 Cache，這樣 Copy() 只會Copy一筆
實測上，原本頁面要跑1.8秒，調整後可以 0.4 秒就完成
-----------------------------------------------------------
結論:
PG產生器就把 GetAllDataFromBaseTableWithCache 拿掉吧

目標收集 SEO 的 10 個最重要的原則. 10 個就好....

1. 每一頁都要有 title, description. 但不可以有 keyword.

2. 使用 URL Rewrite.

3. 產品說明: https://developers.google.com/search/docs/data-types/product

4. 圖片加上 title 和 alt

5. Description 中, 重點關鍵字要出現兩次.

6. 使用 canonical 集合積分統計統果.

點選開始結帳卻發現觸發後面商品數量的select按鈕
若select z-index=200 則蓋在上面的按鈕則z-index=201
上面的z-index要比下面的z-index大
就可以解決了

        {

            //一般 LINQ 寫法, 欄位只能寫死, 如:

            var Q = query.OrderBy(r => r.statusId).ToList();



            //若 OrderBy 的欄位不是固定的



            //方法一：條列

            var orderBy = "XXX";

            if (orderBy == "ownerId")

            {

                Q = Q.OrderBy(r => r.ownerId).ToList();

            }

            else if (orderBy == "endDate")

            {

                Q = Q.OrderBy(r => r.endDate).ToList();

            }



            //方法二：

            Q = Q.OrderBy(r => GetPropertyValue(r, orderBy)).ToList();

        }



        private object GetPropertyValue(object obj, string property)

        {

            System.Reflection.PropertyInfo propertyInfo = obj.GetType().GetProperty(property);

            return propertyInfo.GetValue(obj, null);

        }

1. Go into the Properties window for the project where you want to see stack trace line numbers.
2. Click on the Build "vertical tab".
3. Select "Release" configuration. Check the DEBUG constant parameter.
4. Uncheck the "Optimize code" parameter to avoid the occasional trace issue with inlined code (this step is not essential).
5. Press the Advanced... button and choose Output -> Debug Info -> pdb-only.
6. Deploy the generated .pdb file with the assembly.

 
 
 

以前年輕不懂事, 寫了一些很遜的程式碼, 例如:

舊的程式碼:

        public static DataTable DTFromSQL(string Sql, string DBC = null, Int32 timeout = 0)

        {

            SqlDataAdapter DA = new SqlDataAdapter(Sql, GetDBC(DBC));



            DataTable DT = new DataTable();

            try

            {

                DA = new SqlDataAdapter(Sql, DBC);

                if (timeout > 0)

                {

                    DA.SelectCommand.CommandTimeout = timeout;

                }



                DA.Fill(DT);

            }

            catch (Exception ex)

            {

                throw new Exception(ex.ToString());

            }

            finally

            {

                DA.Dispose();

            }



            return DT;

        }

新的程式碼:

        public static DataTable DTFromSQL(string Sql, string DBC = null, Int32 timeout = 30)

        {

            using (var DA = new SqlDataAdapter(Sql, GetDBC(DBC)))

            {

                //不可為 null

                DataTable DT = new DataTable();



                DA.SelectCommand.CommandTimeout = timeout;



                DA.Fill(DT);



                return DT;

            }

        }

試分析以下兩個 function..

        public static void WriteText1(string FileName, List<string> ltData)

        {

            foreach(string data in ltData)

            {

                System.IO.File.AppendAllText(FileName, data);

            }

        }



        public static void WriteText2(string FileName, List<string> ltData)

        {

            var Res = "";

            foreach (string data in ltData)

            {

                Res += data;

            }



            System.IO.File.WriteAllText(FileName, Res);

        }
