   • How to implement for-else and foreach-else in C# similar to Python's for-else and while-else?

     Top Answer

     Answered Oct 14, 2013 · 22 votes

     The Python Construct for foreach-else is like this:

     foreach( elem in collection ){ if( condition(elem) ) break;}else{ doSomething();}

     The else only executes if break is not called during the foreach loop

     A C# equivalent might be:

     bool found = false;foreach( elem in collection ){ if( condition(elem) ) { found = true; break; }}if( !found ){ doSomething();}

   • How to Create a python Dll file that should be used in C#.net?

     Answered Aug 31, 2011 · 1 votes

     You can compile your Python sources to a DLL with pyc.py, in the Samples directory of IronPython. However, you can't load this DLL from C# directly - you'll still need to host IronPython, but then you can reference the DLL with the IronPython engine and import from it.

   • how to set input and output parameters in arcobjects using c#, which call python script?

     Top Answer

     Answered Apr 15, 2012 · 1 votes

     There is an example in the .NET Developer Help at the Esri pages: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#/Walkthrough_Consuming_a_geoprocessing_model_tool_in_NET/0001000001sw000000/

     Work through it, and you should have learned how to call a geoprocessing tool from ArcMap. To do so, you have to make a toolbox containing your python script. This can be called with .NET code (see the walkthrough).

     Note: Most of this basic development stuff is already well documented at the Esri pages, but sometimes hard to find ;-)

   • Python Classes (object) and Functions (self) in C#

     Top Answer

     Answered Oct 23, 2016 · 1 votes

     Yeah, these are global vars. Your approach is just fine. The 'object' in the parentheses is an inheritance from the class 'object'. As far as you care in this case, you can ignore it. The self in the parentheses is just python syntax, self is the equivalent for 'this' in C#, and you have to specify it in the method's signature. Again, you can ignore it. init is simply the constructor of the class.

   • How Similar are Java, C#, and Python?

     Top Answer

     Answered Jun 07, 2010 · 15 votes

     All:

     • Require some form of runtime on your system (JVM/.net/Python runtime)
     • All can probably be compiled to executables without the runtime (this is iffy and situational, none of them are designed to work this way)
     • Are good languages
     • All have specific areas where they are much more appropriate than the other two

     Java:

     • Tries very hard to be Cross Platform--generally succeeds
     • Little access to platform features that are not in the SDK
     • Slowest of the three to change and does not contain features common to the other two such as closures
     • Very backwards compatible (partly because of the previous point)
     • FAST (about 2x slower than C, quite a few x faster than python)
     • Probably has the most library support of the three
     • Strong multi-platform server systems already deployed using J2EE
     • Scales down to embedded (I've worked on 2 different embedded java projects--coming soon to a cable box near you)
     • Static

     C#

     • Quicker to add new features
     • Windows only--Mono is cross platform but does not have the library support.
     • Started very similar to Java but has many more language features now.
     • Much better access to windows APIs
     • Not sure about speed--I think it's similar to Java.
     • Very good library support
     • The only one of the three that you have to pay for (it's free for "entry level")
     • Static

     Python

     • Language is cross platform. Not sure about non-language platform access (such as drag-and-drop)--anyone know?
     • Probably an easier language to learn
     • The only one of the three that does not use c-like syntax
     • Slowest of the three, but still pretty darn fast compared to other dynamic languages.
     • Dynamic

     Python is a dynamic language where Java and C# are really not. It is totally different than the other two. There are ways to accomplishing things in Python that do not translate well to the others and vice versa.

     Java and C# look the same, but they have differences between the two under the sheets. Being an expert in one, does not make you an expert in the other by any stretch of the imagination. The syntax is similar and libraries are too, so it would be easier to get up to speed in one or the other, but there are subtleties that can trip you up.

     C# and Java have almost identical syntax and very similar libraries. There are differences that you have to be aware of (Type Erasure in Java, for example).

     Python is a completely different animal. It is a dynamic language (where the other two aren't). Python winds up being closer in style to something like Ruby.

   The abstract classes are used to achieve abstraction in C#. Abstraction is one of the important concepts of object-oriented programming. It allows us to hide unnecessary details and only show the needed information.

    How to define an abstract class and abstract methods in C#?

    • So, when a class contains any abstract methods, it must and should be declared using the abstract modifier, and when a class is created using an abstract modifier, it is called an Abstract class in C#. So, this is how exactly we define an abstract class and abstract methods in C#.

    What is an abstract class in Java?

    • An abstract class can also be created without any abstract methods, We can mark a class abstract even if doesn’t have any abstract method. The Abstract classes are typically used to define a base class in the class hierarchy. Or in other words, an abstract class is an incomplete class or a special class we can’t be instantiated.

    Which class should implement all abstract methods?
