从listview中为c＃变量赋值 [英] assign to a c# variable a value from a listview

问题描述

大家好，



我有一个列表视图（从数据库中检索数据）它有列（id，名称，价格，数量）



我想检查数量值，如果var <5则向管理员发送带有产品特征（ID，名称，价格）的电子邮件。



我发现以下代码可以发送电子邮件：

Hi guys,

I have a list view (which is retrieving data from a database) it has columns (id,name,price,quantity)

I want to check the quantity value and if it is var<5 to send an e-mail with products characteristics (id,name,price) to administrator.

I found the following code which works it sends email:

MailMessage mailObj = new MailMessage(
            "from", "to", "Product low quantity", "your product has low quantity");

        SmtpClient SMTPServer = new SmtpClient("localhost");
        try
        {
            SMTPServer.UseDefaultCredentials = false;
            SMTPServer.Host = "smtp.gmail.com";
            SMTPServer.Port = 587;
            SMTPServer.Credentials = new NetworkCredential("email", "password");
            SMTPServer.EnableSsl = true;
            SMTPServer.Send(mailObj);
        }
        catch (Exception ex)
        {
            // Label1.Text = ex.ToString();
        } 

所以我想以某种方式检查产品的数量



任何帮助？

推荐答案

嘿那里，



试试这个：

首先添加 DataKeyNames ListView的属性，如： DataKeyNames = 数量

并使用此代码检查数量：

Hey there,

Try this:
Add DataKeyNames property of ListView first, like: DataKeyNames="quantity"
and Use this code to check quantity:

foreach (ListViewDataItem item in ListView1.Items)
            {
                int quantity = Convert.ToInt32(ListView1.DataKeys[item.DisplayIndex]["quantity"].ToString());
                if (quantity < 5)
                {
                    //Send Email here
                }
            }

您可以获得与Quanity相似的特定行的其他值。



希望它有帮助
