linq - Is it possible to construct a stringbuilder using a lambda function instead of foreach? -


संभव डुप्लिकेट:

मेरे कार्यात्मक प्रोग्रामिंग नोनिजन को माफ़ कर दें, लेकिन क्या स्ट्रैन्बिलिल्डर ऑब्जेक्ट में प्रत्येक स्ट्रिंग को जोड़ने के लिए लंबा फ़ंक्शन का उपयोग करना संभव है?

क्या यह कोड चालू करना संभव है: 

  // स्ट्रिंग [] त्रुटियां = ... स्ट्रिंगबिल्ल्डर sb = नया स्ट्रिंगबिल्डर ("& lt; ul>"); विदेशी (त्रुटियों में त्रुटि) {sb.AppendFormat ("& lt; li> {0} & lt; / li>", त्रुटि); } Sb.AppendLine ("& lt; / ul"); वापसी sb.ToString ();

इस तरह से कुछ में: 

  // स्ट्रिंग [] त्रुटियां = ... स्ट्रिंगबइल्डर एस.बी. = नया स्ट्रिंगबिल्डर ("& lt; ul>"); // मुझे पता है यह सही नहीं है, मुझे कोई वापसी मूल्य त्रुटियों की परवाह नहीं है। सभी (s => sb.AppendFormat ("& lt; li> {0} & lt; / li>", s)); sb.AppendLine ( "& lt; / उल"); वापसी sb.ToString ();

किसी भी सुधार के लिए धन्यवाद!

मैंने परीक्षण नहीं किया है यह, लेकिन कुछ जैसे निम्नलिखित कार्य करना चाहिए ... 

  वापसी त्रुटियां। अगागेट (नया स्ट्रिंगबिल्डर ("& lt; ul & gt;"), (sb, s) = & gt; sb.AppendFormat "& Lt; li & gt; {0} & lt; / li & gt;", s))। एपेंड ("& lt; / ul & gt;"); ।तार();

कुल एक IEnumerable विस्तार विधि है ... लेकिन मेरे पास जटिल त्रुटियों का क्रम हो सकता है व्यक्तिगत रूप से, मुझे नहीं लगता कि यह आपको कम पढ़ा जाने के बाद से इसे खरीदता है, और आंतरिक रूप से एक foreach कर रहा है।

.net - C# List<T>.Find(x=>x.Rectangle.Contains(Point)) FAIL -

For my life, I can not understand why this code generates the following output ... I think there is a bug or something while using the list and lambda, if type one rectangle exposes the property and you use the included method of rectangle object ... and the clear statement proves true while Find list method fails .... Onway Code Public Gridskeyr Warldtokapadsb (Point location) {location = _Map.WorldToClient (location); Gridsquare gs = this.find (x => x.Rectangle.Contains (location)); GridSquare KP = G.Find (X => X. laxative canteen (location)); & Lt; GridSquare & gt; List = kp.FindAll (x => x.Rectangle.Contains (location)); U.dp (list.Count); Gridskare sub = KP.Fid (X => X. laxative canteen (location)); If (sub == faucet) {u.dp (place to look for "location"); U.dp ("The location found in the grid category" + GS toaster ()); U.dp ("Grid Square Bounds" + gs.Rectangle.ToString ()); U.dp ("location found in keypad" +...

I am making my own UITableViewCells with a gradient background. I have worked all the logic and drawing, but the one that I want to fix is ​​"chunky" around the corners of my custom cell: If you have corners, you See what I'm talking about. Here is the code that I am using to generate cells: CGCTXT C = UigRxGroupCertexConnect (); CGColorSpaceRef myColorSpace = CGColorSpaceCreateDeviceRGB (); CGGradientRef myGradient = Zero; CGFloat component [8] = TABLE_CELL_BACKGROUND; CGContextSetStrokeColorWithColor (C, [[UAColor colorWithWhite: 0.7 alpha: 1] CGColor]); CGContextSetLineWidth (C, 2); CGContextSetAllowsAntialiasing (C, Yes); CGContextSetShouldAntialias (C, Yes); CGFloat minx = CGRectGetMinX (RECT), MIDX = CGRactgetMIDX (RECT), MAX x = CGTXxX (RECT); CGFloat miny = CGRectGetMinY (Rect), maxy = CGRectGetMaxY (rect); CGMutablePathRef Path = CGPathCreateMutable (); CGPathMoveToPoint (path, NULL, minx, miny); CGPathAddArcToPoint (default margin of path, NULL, mix, ...

Best practice for URL redirection in ASP.NET web application -

I have an asp page (Default.aspx) that shows the difference between two text files. It has two drop down lists (respectively id = "file1" and "file2" respectively) and a button (id = "submit"). There is also a lexical control with the id "result". The content of the list button is populated based on the files present in the physical application path. Each time the submit button is clicked, I want to give the result of diff / comparison in literal control, so I have an event handler like this: protected Zero Submit_Click (Object Sender, EventArgs e) {Results.First = Comparison Files (File 1. Selected Price, File2.SelectedValue); } The problem with this is that you can not bookmark results of comparison between specific files. To solve this problem, I compare the values ​​of the selected files as a query string for the added URL and made a redirection. And so, the above event handler has been changed to look like this: Protecte...
