C＃ - 在特定时间触发winform app [英] C# - trigger winform app at a specific time

问题描述

我正在开发小型winform应用程序，以便在每天的特定时间向客户发送自动电子邮件。客户将从UI设置时间，因此当系统时间=客户设置的时间时，我的应用程序将发送电子邮件。我添加了一个datetimepicker，客户在其中设置了所需的触发时间。定制日期时间选择器的格式到时间。

  private   void  timer1_Tick（ object  sender，EventArgs e）
 { 
 timer1.Enabled =  true ; 
 timer1.Interval =  1000 ; 
 toolStripTextBox1.Text = DateTime.Now.ToString（  dd-MM-yyyy） ; 
 toolStripTextBox2.Text = DateTime.Now.ToString（  h：mm：ss tt ）; 
 
} 

  private   void  Form1_Load（ object  sender，EventArgs e）
 {
 
 dateTimePicker1.Format = DateTimePickerFormat.Time; 
 dateTimePicker1.ShowUpDown =  true ; 
 dateTimePicker1.CustomFormat =   h：mm：ss tt; 
 dateTimePicker1.Value = DateTime.Now; 
} 
 

我现在很困惑，如果在datetimepicker.value = toolStripTextBox2.Text如何comapre？因为即使我是comapre，也没有错误，但仍然没有发送电子邮件。



我尝试了什么：



if（dateTimePicker1.Value.ToString（）== toolStripTextBox2.Text）

{

textBox3.Text =问题解决了;

}

解决方案

文本框的目的是什么？加载时的所有应用程序需求都是从用户获取时间值。然后它将该时间保存为变量，然后可以将其与时钟时间进行比较，以便决定何时发送电子邮件。

我建​​议你使用 Windows任务计划程序 [ ^ ]。

I am developing small winform app to send an automatic email to customer at a specific time everyday.The customer will set the time from the UI, so when the system time = time set by customer, my app will send email. I included a datetimepicker in which customer set his desired trigger time. The customized the format of date time picker to time.

private void timer1_Tick(object sender, EventArgs e)
        {
            timer1.Enabled = true;
            timer1.Interval = 1000;
            toolStripTextBox1.Text = DateTime.Now.ToString("dd-MM-yyyy");
            toolStripTextBox2.Text = DateTime.Now.ToString("h:mm:ss tt");
           
        }

private void Form1_Load(object sender, EventArgs e)
       {

           dateTimePicker1.Format = DateTimePickerFormat.Time;
           dateTimePicker1.ShowUpDown = true;
           dateTimePicker1.CustomFormat = "h:mm:ss tt";
           dateTimePicker1.Value = DateTime.Now;
       }

I am confused now that, how to comapre if datetimepicker.value = toolStripTextBox2.Text? Because even if I comapre, there is no error but still email is not getting sent.

What I have tried:

if (dateTimePicker1.Value.ToString() == toolStripTextBox2.Text)
{
textBox3.Text = "problem solved";
}

解决方案

What is the purpose of the textboxes? All the app needs on load is to get the time value from the user. It then saves that time as a variable, and can then compare that to the clock time, in order to decide when to send the email.

I suggest you to use the Windows Task Scheduler[^] instead.
