Question

我尝试生成16位代码，当我添加记录时，所有数字都相同，我该如何解决？

循环中的

代码[i] = Newcode;当代码添加到列表中时，代码是核心，将最后一个代码更改为新代码，因此所有代码都与上一次生成相同!!!!



public ActionResult Gen5Rm(GenerateCodeModel model){

        Code Newcode = new Code();

        int X = Convert.ToInt32(model.Quntity);

        Code[] code = new Code[X];

        for (int i = 0; i < X; i++)
        {      
                string strDate = "";
                string strmonth = "";
                string strday = "";
                string myday = "";

                strmonth = DateTime.Now.ToString("MM");
                myday = DateTime.Now.DayOfWeek.ToString();


                if (myday == "Sunday")
                {
                    strday = "SU";
                }
                if (myday == "Monday")
                {
                    strday = "MO";
                }
                if (myday == "Tuesday")
                {
                    strday = "TU";
                }
                if (myday == "Wednesday")
                {
                    strday = "WE";
                }
                if (myday == "Thursday")
                {
                    strday = "TU";
                }
                if (myday == "Friday")
                {
                    strday = "FR";
                }
                if (myday == "Saturday")
                {
                    strday = "ST";
                }
                strDate = generateBarcode();
                Newcode.codebase = model.Agent + strmonth +
            model.Type_Code + strDate + strday + "5" + model.Dealercode;
                Newcode.price = 5;
                Newcode.serial = "S" + DateTime.Now.ToString("mmssfff");

                code[i] = Newcode;
         }

        return PartialView("_return5rm", code);
        }

public ActionResult Gen5Rm(GenerateCodeModel model){ Code Newcode = new Code(); int X = Convert.ToInt32(model.Quntity); Code[] code = new Code[X]; for (int i = 0; i < X; i++) { string strDate = ""; string strmonth = ""; string strday = ""; string myday = ""; strmonth = DateTime.Now.ToString("MM"); myday = DateTime.Now.DayOfWeek.ToString(); if (myday == "Sunday") { strday = "SU"; } if (myday == "Monday") { strday = "MO"; } if (myday == "Tuesday") { strday = "TU"; } if (myday == "Wednesday") { strday = "WE"; } if (myday == "Thursday") { strday = "TU"; } if (myday == "Friday") { strday = "FR"; } if (myday == "Saturday") { strday = "ST"; } strDate = generateBarcode(); Newcode.codebase = model.Agent + strmonth + model.Type_Code + strDate + strday + "5" + model.Dealercode; Newcode.price = 5; Newcode.serial = "S" + DateTime.Now.ToString("mmssfff"); code[i] = Newcode; } return PartialView("_return5rm", code); }

the export is like this

Newcode应该在for循环中，否则数组中的所有项都将指向同一个对象（相同的内存地址）

for (int i = 0; i < X; i++)
{ 
    Code Newcode = new Code();
    ...
}

生成代码和更新列表时出错
