c# - Subtracting properties in a list using LINQ -

-

मेरे पास निम्न है: (सी # कोड, वी.एस.2013) 

  क्लास डेलीटेम्प {सार्वजनिक इंट डे; सार्वजनिक इंक LowTemp; सार्वजनिक इंक उच्चटाम; } सूची & lt; DailyTemp & gt; DailyTemps = नई सूची & lt; DailyTemp & gt; (); // मैं डेलीटेम्प ऑब्जेक्ट्स के साथ इस सूची को भरता हूं

मेरा सवाल है, मैं अपनी सूची के माध्यम से जाने के लिए लैम्ब्डा अभिव्यक्ति कैसे लिखूं और उस दिन को वापस लौटाता हूं जिसमें उच्च और निम्न टेम्पम्स के बीच सबसे छोटा अंतर होता है ? आपके समय के लिए शुक्रिया।

कोशिश करें: 

  दैनिक टेम्प्स। ऑर्डरबी (डीटी = & gt; Dt.HighTemp - dt.LowTemp)। चुनें (डीटी = & gt; dt.Day)। पहले (); जैसा कि @Colin DeClue द्वारा नोट किया गया है, यह  कॉल करें  से पहले  पहले  कॉल करने के लिए और अधिक कुशल है ताकि हम न्यूनतम जरूरी जानकारी पुनः प्राप्त कर सकें डेटा स्रोत से (जो कि डीबी से आने वाले बड़े डेटा सेटों पर फ़र्क पड़ता है)।

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
