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

 

        public void TEST(SEPM.SEPMDataContext oDC)

        {

            //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);

        }

            List<int> listLinq = new List<int>(Enumerable.Range(0, dt.Rows.Count - 1));

            listLinq = listLinq.OrderBy(num => rand.Next()).ToList<int>();

程式碼 1:

        {

            var oSP = new DB.StorePointRecord(oRow);

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);

        }

轉換文章內容成為excel 檔案的時候
發生的錯誤
網路上查都好像是跟圖片有關的錯誤
後來才確認是 emoji 的問題
文章裡有出現

🙋‍♀️🙋‍♀️🙋‍♀️

這種東西 

SQL:
SQL 好像也沒辦法完美的取代 ( 如果有辦法對準是哪個字元就可以 但如果是一個字串好像會無法取代)
只有剛好對到那個字元開頭時才能換
NCHAR(65039)  NCHAR(8205)

Select TOP 10 
Replace(SUBSTRING(content,10,15),NCHAR(65039) ,'XX') ,                                    ---HongKong‍️‍️‍️🙋‍♀️怎
REPLACE(SUBSTRING(content,17,8),NCHAR(65039),'OO')                                        ---OO怎 
FROM [Table] 


C#
最後回到C#來處理
首先用 把string  .ToArray() 變成char
找出字元後 轉成 int 來確認要怎麼表達這個 char
最後結果就變成>>
Convert.ToInt32(Table.Rows[0]["Content"].ToString().ToArray());
之後直接變成 char去取代
row["mycolumn"].ToString().Replace((char)65039, ' ').Replace((char)8205, ' ');
然後就暫時 沒錯誤了
只是這網站一直再更新
https://emojipedia.org/unicode-12.0/

所以未來可能還會有新的問題
目前還不知道甚麼快速的解法
