c# - How to perform 2 checks in LINQ Where -

- 

  सार्वजनिक सूची & lt; SavedOption & gt; GetValidSavedOptions (सूची & lt; विकल्प & gt; आइटम विकल्प, सूची & amp; लिफ्ट; सहेजा गया विकल्प & gt; सहेजे गए ऑप्शन) {सूची & lt; सहेजा गया विकल्प & gt; अंतिम सहेजे गए विकल्प = सहेजे गए विकल्प। कहाँ (x = & gt; विकल्प पाठ DoesMatch (y, x) & amp; amp; ItemOptions.Any (y = & gt; y.SomeID == x.SomeID))। सूची (); }

मैं पूरी तरह से LINQ और लैम्ब्डा के लिए नया हूँ

उपरोक्त में, मुझे क्या चाहिए / क्या करना है सहेजा गया विकल्प में केवल अगर कॉल को OptionTextDoesMatch और SomeID सहेजे गए विकल्प की SomeID में itemOptions की सूची में पाया जाता है। अगर OptionTextDoesMatch पर कॉल true और मौजूदा सहेजे गए ऑप्शन savedOption.SomeID को itemOption में मिलता है संग्रह तब यह toList ()

में होगा:

मैंने इसे करने की कोशिश की लेकिन वाक्य रचना अभी भी मेरे लिए काम नहीं कर रही है:

सहेजे गए ऑप्शन। जहां (आइटम विकल्प। कोई भी (वैकल्पिक पाठ मैप्स (एक्स, वाई) & amp; (y => y.SomeID == x.SomeID)))। ToList ();

अब मुझे नहीं पता कि क्या मैं एक्स में ऐसे ही फेंक सकता हूं। मुझे लगता है कि अगर मैं ऐसा करता हूँ तो वह सहेजे हुए कर्त्तव्य का प्रतिनिधित्व करने जा रहा है और मुझे =>?

<पी > यादृच्छिक अनुमान: 

  सूची & lt; सहेजा गया विकल्प & gt; अंतिम सहेजे गए विकल्प = सहेजे गए विकल्प। कहाँ (x = & gt; आइटम विकल्प। कोई भी (y = & gt; विकल्प पाठ डाइम्स मैच (y, x) & amp; y.SomeID == x.SomeID)) .सूची ();

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option. However, when I select a new value and I save ...

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
