powershell 2.0 try catch how to access the exception -


यह PowerShell 2.0 में पकड़ने का प्रयास करें 

  $ urls =" http://www.google.com "," http://none.greenjump.nl "," http://www.nu.nl "$ wc = नई ऑब्जेक्ट सिस्टम। नेट। वेबक्लेक्चर विदेशी ($ url में $ url) {{$ url $ परिणाम = $ wc.DownloadString ($ url)} को पकड़ें [System.Net.WebException] {[void] $ fails.Add ( "Url webfailed $ url")}}

लेकिन मुझे क्या करना है, कुछ ऐसा है जैसे c # 

  पकड़ (वेबएक्सेशन पूर्व) {लॉग (ex.ToString ()); }

क्या यह संभव है?

ऐसा कुछ करने की कोशिश करें: 

  प्रयास करें {$ w = नया ऑब्जेक्ट नेट। वेबक्लाइंट $ d = $ w.downloadString ('http: // foo')} पकड़ [ Net.WebException] {लिखें- होस्ट $ _। अपवाद.ToString ()}

अपवाद $ _ चर में है आप $ _ इस तरह से एक्सप्लोर कर सकते हैं: 

  प्रयास करें {$ w = नया ऑब्जेक्ट net.WebClient $ d = $ W.downloadString ('http: // foo')} पकड़ [नेट। वेब एक्सपेक्शन] {$ _ | मुझे लगता है कि यह आपकी सभी आवश्यक जानकारी देगा।  
 मेरा नियम:  यदि कोई ऐसा डेटा है जो प्रदर्शित नहीं होता है  -force   का उपयोग करने का प्रयास करें।

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
