c# - LINQ to Entities does not recognize the method 'Int32 ToInt32(System.String)' method -

-

I checked online for some answers, and I understood that I can not translate ToInt32 into T-SQL , And I need to use the running of my query, before the memory and then the conversion, but I do not know how to apply it in my example. I have a query below, and it shows me the error message written in the title: 

  string [] parts = rvm.ZipCode.Split ('-'); Var list = result Orterby (B = & gt; Math.bs (Convert .OIT 32 (Part [0]) - Convert.OINIT32 (B.Zip)). Take (5) .Ollist ();   
 Where  results  is another query I applied earlier. How to solve any idea?   
 
 
 You can try to do something like this:  
  // It would be better if we change the conversion only once, then each Time we take an item from our collection. Nt value = convert toint32 (parts [0]); var list = results.AsEnumerable (). OderBy (z = & gt; Math.Ebus (value - convert toInt32 (z.Zip)). Take (5 ) .toList ();

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
