c# - 将类的对象添加到同一类C#的数组中

Question

大家好 ，我尝试将一组ٍStrings转换为一个类，然后将这些元素添加到同一类的数组或列表中

问题 一切都很好，只有添加一个元素时，它才会将数组中的所有值更改为与最后一个元素相同的值

文本Cookie.文本：

1=|257|9.5|1|true|true|true|true|1-来自网络，2=|259|11.5|7|false|false|false|false|232-来自网络，3=|261|9.5 |5|true|false|true|true|-来自网络，4=|267|9.5|1|true|true|true|true|-来自网络

这段代码：

        //Get The Value from Text Box To list of Strings
        string[] lst = TxtCookie.Text.Split(',');
        //Divide each element into a set of values
        var D = (from a in lst select a.Split('|')).ToList();

        //Define an object from the class
        TblInvoiceContent tblInvoiceContent = new TblInvoiceContent();
        //Define an List from the class
        List<TblInvoiceContent> TBLIC = new List<TblInvoiceContent>();

        //Here I take the values and configure them according to the class structure
        foreach (var item in D)
        {
            tblInvoiceContent.ItremID = Convert.ToInt32(item[1]);
            tblInvoiceContent.SilingPrice = Convert.ToDouble(item[2]);
            tblInvoiceContent.Quantity = Convert.ToInt32(item[3]);
            tblInvoiceContent.mayonnaise = Convert.ToBoolean(item[4]);
            tblInvoiceContent.ketchup = Convert.ToBoolean(item[5]);
            tblInvoiceContent.Hot = Convert.ToBoolean(item[6]);
            tblInvoiceContent.garlic = Convert.ToBoolean(item[7]);
            tblInvoiceContent.Reqomindition = item[8].ToString();
            //Here I add the item to the list
            TBLIC.Add(tblInvoiceContent);

        }
        //Here I am displaying the list items
        GridView1.DataSource = TBLIC;
        GridView1.DataBind();

结果 ：

    string[] lst = TxtCookie.Text.Split(',');
    //Divide each element into a set of values

    //Define an List from the class
    List<TblInvoiceContent> TBLIC = new List<TblInvoiceContent>();

    //Here I take the values and configure them according to the class structure
    foreach (var item in D)
    {
        //CALL IT HERE Define an object from the class
        TblInvoiceContent tblInvoiceContent = new TblInvoiceContent();

        tblInvoiceContent.ItremID = Convert.ToInt32(item[1]);
        tblInvoiceContent.SilingPrice = Convert.ToDouble(item[2]);
        tblInvoiceContent.Quantity = Convert.ToInt32(item[3]);
