c# - Easier way of checking Int32.TryParse -

-

I'm looking at all these in a method in your code: 

  int num1 = 0; If (four. Aisdigit (Maistret [2]) & amp; Int 32. Tryprs (Maistr [2]. Tustring (), out of 1 points) == false) {valid = false; }   
 So are they making sure that the third letter gives us a score?   
 
 
 It seems that doing so efficiently that you have code that is coded he knows  myStr  the structure of the string, sometimes a non-numerical symbols on the third place, which is why he third before having to pay for the conversion of the array of character strings Created this optimization to check the symbol.  
 Chances are, it's customizable time: although temporary throw-not far string free, this optimization will only be in situations when you do it a lot in very tight loop. In other words, you only do when it appears at the top of the output of your display profiler.  
 You can customize this check to avoid  if :  
  integer number 1 = 0; Legal & amp; =! Char.IsDigit (myStr [2]) || Int32.TryParse (myStr [2] .tostring (), out num1);

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...
