.net - IL Opcode Modification -


भाषा: VB.NET 3.5

आईएल ओपोडोड: 

  718 ldarg.0 719 कॉलविर्ट सिस्टम.विंडो.फॉर्म.बटन आरक्लिएन्ट .आर क्लाइंट :: मिलग्रेड (724) ldarg.0 725 ldfld System.String [] RClient.RClient :: बटनट्रेस्टिंग 730 ldc.i4.5 731 ldelem.ref 732 callvirt System.Void System.Windows.Forms.ButtonBase :: set_Text (System.String) 737 ldarg.0

के अनुरूप: 

  Me.cmd1 टेक्स्ट = मी.बटन एसटिंग्स (5)

कम से कम मेरा मानना ​​है कि ऐसा होता है। आईएल में क्या बदलाव होगा, इसके बजाय इसे प्रतिबिंबित करना होगा: 

  Me.cmd1.Text = "कुछ स्ट्रिंग"  

  ldarg.0 कॉलविर्ट सिस्टम। विन्डोज.फॉर्म। बटन आर क्लाइंट .आर क्लाइंट :: मिलीग्राम () ldstr "कुछ स्ट्रिंग" कॉलविर्ट सिस्टम। वीड सिस्टम । खिड़कियों.फॉर्म। बटनटन :: सेटहोस्ट (सिस्टम.स्ट्रिंग)

रेखा 1 धक्का पर मेरे धक्का देता है। रेखा 2 विधि get_cmd1 को कार्यान्वित करता है जो ढेर के शीर्ष पर ऑब्जेक्ट के लिए संपत्ति के लिए प्राप्तकर्ता से संबंधित है cmd1 इसलिए, इस लाइन को स्टैक के ऊपर ऑब्जेक्ट से प्राप्तकर्ता cmd1 के परिणाम को धक्का जाता है, इस प्रक्रिया में स्टैक के ऊपर पॉपिंग होता है। रेखा 3 स्टैक पर "कुछ स्ट्रिंग" धक्का देता है। इस बिंदु पर स्टैक "कुछ स्ट्रिंग" और स्टैक पर अगले आइटम Me.cmd1 है। रेखा 4 स्ट्रेट के शीर्ष वाले स्ट्रिंग पैरामीटर के साथ विधि set_Text को कार्यान्वित करता है यह स्टैक पर दूसरे आइटम के लिए टेक्स्ट के लिए सेटर से मेल खाती है स्टैक पर दूसरा आइटम Me.cmd1 है। इसलिए ये रेखाएं Me.cmd1.Text = "कुछ स्ट्रिंग" के बराबर हैं।

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...
