It should work this way.

<pre><code>if (DateTime.TryParse(i, out dateValue))
{
 if (dateValue.ToShortTimeString() == DateTime.ToString("dd hh:mm tt"))
 {
 //do something here
 }
}
</code></pre>

dd tells to show the current day. hh displays the hours and mm the minutes. I left ss for seconds because it seems you don't need it. Through tt PM or AM will get displayed.

You are trying to compare <code>Time</code> value with <code>DateTime</code> value. I think you just want to compare that Time values of your <code>array</code> to <code>current</code> time value, in that case you can compare time part of the dates.

<pre><code>if (DateTime.TryParse(i, out dateValue))
{
 if (dateValue.ToShortTimeString() == DateTime.Now.ToShortTimeString())
 {
 //do something here
 }
}

blocks|key|18998|text|首先，您需要将调度字符串数组中的时间转换为DateTime。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|18999|关于DateTime样式的链接：http://www.csharp-examples.net/string-format-datetime/|offset|length|19000|在那之后，你只需要比较两个日期的时间部分。答案从这里开始：How+to+compare+time+part+of+datetime|19001|所以，最后你的代码应该是这样的：|19002|string[]+schedule+=+{+"Thursday+2:47+PM",+"Thursday+2:50+PM",+"Thursday+2:55+PM"+};
private+void+timer1_Tick(object+sender,+EventArgs+e)

First, you need to convert time in schedule string array into DateTime.

Link about DateTime styles: <a href="http://www.csharp-examples.net/string-format-datetime/" rel="nofollow noreferrer">http://www.csharp-examples.net/string-format-datetime/</a>

After that, you need to compare only time part of 2 dates. Took the answer from here: <a href="https://stackoverflow.com/questions/10290187/how-to-compare-time-part-of-datetime">How to compare time part of datetime</a>

So, finally your code will be something like this:

<pre><code>string[] schedule = { "Thursday 2:47 PM", "Thursday 2:50 PM", "Thursday 2:55 PM" };
private void timer1_Tick(object sender, EventArgs e)
{
 DateTime dateValue;
 foreach (var i in schedule)
 {
 if (DateTime.TryParseExact(i, "dddd h:mm tt", CultureInfo.CreateSpecificCulture("en-US"), DateTimeStyles.None, out dateValue))
 {
 var currentDate = DateTime.Now;
 if (dateValue.DayOfWeek == currentDate.DayOfWeek &amp;&amp; dateValue.TimeOfDay == currentDate.TimeOfDay)
 {
 //do something here
 }
 }
 }
}

private void Form1_Shown(object sender, EventArgs e)
{
 timer1.Start();
}
</code></pre>

Of course, you can convert DateTime.Now to a string of valid format (as in your string array) but I think that it's wrong. If you want to check that your date is earlier or later than current date, you will have to rewrite your code.

I want to know how can I format <code>DateTime.Now</code> in this same format <code>Thursday 03:00 PM</code> so that I can compare it to my custom format date time value,

I am trying to create a simple scheduling system, that if a specific date time will be equivalent to current date time a code will run under it but I am stuck in comparing my custom dates to current date time

<pre><code>string[] schedule = { "Thursday 2:47 PM", "Thursday 2:50 PM", "Thursday 2:55 PM" };
 private void timer1_Tick(object sender, EventArgs e)
 {
 DateTime dateValue;
 foreach (var i in schedule)
 {
 if (DateTime.TryParse(i, out dateValue))
 {
 if (dateValue == DateTime.Now)
 {
 //do something here
 }
 }
 }
 }

 private void Form1_Shown(object sender, EventArgs e)
 {
 timer1.Start();
 }
</code></pre>
