c# - A better way to do this LINQ query? -

-

I have a collection of data objects that can not be directly accessible to each other. I think the best solution is to To create a question would be to get the database people, but in the meantime, is there some way to strengthen it up? Conflicting = allFoos.Where (foo = & gt; foo.ElectronicSerialNumber = 0 & amp;! Foo.BarID = interestingBar.ID) 

  .Join (fooInfoCollection, foo = & Gt; foo.ElectronicSerialNumber, fooInfo = & gt; fooInfo.ElectronicID, (foo, fooInfo) & gt; foo) .Join (allBars, foo = & gt; foo.BarID, bar = & gt; bar.ID , (Foo, bar) => bar). Where (bar = & gt; bar.SomeCriteria == incorrect). FirstOrDefault (); If (conflicting! = Zero) {doStuff (conflicting); }  itemprop = "text"> 
 It looks like you've got all the foos, all the FooInfos and all the bars from the

Database so that you can do a query where you only need the object once in the form of a result. If you have to exclude all these items from the database for any other query then this is okay, but if you find all of these items for just one query then it is extremely incompatible. You should try to perform the query and retrieve the database returned only one object.

Even if there are no foreign keys lacking, you can still get it, and you can do Linq to type in between sql even if they In fact, they are not present in the database, which makes it easy to prepare your questions.

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.
