输入时间并根据System.DateTime进行检查 [英] Inputting a time and checking it against System.DateTime

问题描述

您好，



我在检查用户输入当前时间的时间时遇到了麻烦。



代码在一个计时器（每秒检查一次）。



到目前为止我得到了什么：



private void timer1_tick（object sender，EventArgs e）

{

_datetimetocheck = convert.todatetime（txtbxtimeinput.text）



if（_datetimetocheck == _datetimenow）< br $>
{

Console.Beep（10,1000）;

MessageBox.Show（testing）;

}



}



感谢任何建议:)



问候，

Hello,

I am having troubles checking a time that a user inputs against the current time.

The code is in a timer (which is checking the time every second).

What I have got so far:

private void timer1_tick(object sender, EventArgs e)
{
_datetimetocheck = convert.todatetime(txtbxtimeinput.text)

if(_datetimetocheck == _datetimenow)
{
Console.Beep(10,1000);
MessageBox.Show("testing");
}

}

Any suggestions are gratefully received :)

Regards,

Glen Childs

推荐答案

private void timer1_Tick(object sender, EventArgs e)
{
    DateTime date1 = Convert.ToDateTime(txtbxtimeinput.Text);
    DateTime date2 =DateTime.Now;

    if (date1.ToString() == date2.ToString())
    {
        Console.Beep(37, 1000);
        MessageBox.Show("testing");
    }
}

像这样使用

use like this

string format = "M:dd:yyyy h:mm:ss"
           string s= (DateTime.Now.ToString(format));
if(_datetimetocheck == s)
{
//do something
}

如果用户输入月份，日期和年份也

else

if the user enters month,date and year also
else

string format = "h:mm:ss";
string s= (DateTime.Now.ToString(format));

if(_datetimetocheck == s)
{
//do something
}
</pre>

嗨Glen！



我不知道你试图通过每秒运行的计时器实现什么，但是如果你想要像验证这样的东西你应该使用像文本框上的 TextChanged 或 KeyDown 。



with keydown它看起来像这样：

Hi Glen!

I dont know what you try to achieve with the timer running every second, but
if you want something like a validation you should use events like TextChanged or KeyDown on the textbox.

with keydown it could look something like that:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
   if (e.Key != Key.Enter) return;

   DateTime dtToCheck = DateTime.Today;

   DateTime inputParsed;
   DateTime.TryParse(textBox1.Text, out inputParsed);

   if (inputParsed != null)
   {
      //uncomment line above if you want to use autocomplete
      //textBox1.Text = inputParsed.ToString();

      if (inputParsed.Equals(dtToCheck))
      {
          //match!
      }
   }
}
