WPF determines whether the date is a work day or holiday, or a wpf holiday

WPF determines whether the date is a work day or holiday, or a wpf holiday

Get returned information via API (http://www.easybots.cn/holiday_api.net)

Write a function for receiving feedback IsHoliday

Public string IsHoliday (string date) {string url = @ "http://www.easybots.cn/api/holiday.php? D = "; url = url + date; HttpWebRequest httpRequest = (HttpWebRequest) WebRequest. create (url); httpRequest. timeout = 2000; httpRequest. method = "GET"; HttpWebResponse httpResponse = (HttpWebResponse) httpRequest. getResponse (); StreamReader sr = new StreamReader (httpResponse. getResponseStream (), System. text. encoding. getEncoding ("gb2312"); string result = sr. readToEnd (); result = result. replace ("\ r ",""). replace ("\ n ",""). replace ("\ t", ""); int status = (int) httpResponse. statusCode; sr. close (); return result ;}Holiday Functions

Based on the API, you can find that the returned content includes the following three types:
{& Quot; 20130101 & quot;: & quot; 2 & quot "}

{& Quot; 20130103 & quot;: & quot; 1 & quot "}

{& Quot; 20130201 & quot;: 0}

Because we only need to determine whether it is a working day, we need to determine two types, that is, 0 or not.

If the value is 0, "" does not exist, and "" exists for 1 and 2. Note that

Simple Field Truncation

Substring (s. length-2, 1 );

You can determine whether the intercepted field is 0.

Then write a MouseLeave event to the datepicker control.

Private void DP_MouseLeave (object sender, MouseEventArgs e) {string date = Convert. toDateTime (DP. text. toString ()). toString ("yyyyMMdd"); string num = IsHoliday (date ). substring (IsHoliday (date ). length-2, 1); switch (num) {case "0": TB. text = "workday"; break; default: TB. text = "Holidays"; break ;}}Departure event of the Time Control

As follows:

Of course, the first two days of News said that some units in Beijing had a holiday in November 7-12, which is not supported.

 

C # enter a time period to determine the number of working days in the time period (excluding holidays)

I wrote it and implemented it using an extension method. I have made some adjustments according to the answers in a Foreign Forum. Thanks to Alexander! The following is the complete source code with the core code in the attachment. If you have any questions, please contact us.

Note: The original method is very well written. You can specify a national holiday, but it is not used in the instance source code. Please take a look at it yourself.
