C# How to create a generic list of students and grades and access those -

-

I'm struggling with something on C # which should be really easy for me in an unknown number of students Storage system is needed and unknown number of features about each student are required.

I am basically finding an unknown number of students, grades and other information which is different from any other student. Student 1: Name: John Last Name: DOE Math 1010: A Math 2020: B Math 3010: B + England 1010: A - < Li>

Student 2: name: April: last name: Johnson Geology 1000: C. Math 1010: b etc. ...

Finally, let me each student Need to take steps through and produce your information.

I found this example which is good for a set of known items per student, but I think that I need a list for each student, and I'm not sure that the "master" list How to make it I can understand it for arrays, but the working generator is new to me. 

  list & lt; Students & gt; LstStudents = New list & lt; Students & gt; (); Student objStudent = new student (); ObjStudent.Name = "Silver"; ObjStudent.RollNo = 1; LstStudents.Add (objStudent); ObjStudent = new student (); ObjStudent.Name = "Sam"; ObjStudent.RollNo = 2; LstStudents.Add (objStudent); // Luping (student stस्ट in alestustants) through the list of students {// No need to type because the compiler already knows that everything inside this list // is a student console.Vrightline ("roll # "+ CurrentStell Rollo +" "+ Current ST.Name); }  "post-text" itemprop = "text"> 
 You can declare as a student class:  
  public class student {Private Redoni Dictionary & lt; String, Object & gt; _customProperties = New Dictionary & lt; String, Object & gt; (); Public dictionary & lt; String, Object & gt; Custom Properties {Back {_customProperties; }}}   
 and then use it:  
  list & lt; Students & gt; LstStudents = New list & lt; Students & gt; (); Student objStudent = new student (); ObjStudent.CustomProperties.Add ("name", "silver"); ObjStudent.CustomProperties.Add ("RollNo", 1); LstStudents.Add (objStudent); ObjStudent = new student (); ObjStudent.CustomProperties.Add ("name", "Sam"); ObjStudent.CustomProperties.Add ("RollNo", 2); LstStudents.Add (objStudent); Foreign Language (studio status in list students) {Forchach (in current students corporate properties) • Console Virline (Prk + K + "+ PrP value);}}

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...
