Possible Duplicate: What is the difference between a field and a property in C# I'm a beginning programmer and I've read all about class properties. Books state that properties allow you to indirectly access member variables. Ok, so what makes it any different than just making the field public and accessing it directly? Here's a quote from Learning C# 3.0 by Jesse Liberty: For example, you might want external classes to be able to read a value, but not change it; or you might want to write some code so that the internal field can accept only values in a certain range. If you grant external

my scenario is as follows:: class Parent { public: int x; } class Child:public Parent { int x; // Same name as Parent's "x". void Func() { this.x = Parent::x; // HOW should I access Parents "x". } } Here how to access Parent's "X" from a member function of Child. Almost got it: this->x = Parent::x; this is a pointer. Accessing it via the scope resolution operator will work: x = Parent::x; However, I would question in what circumstances you want to do this. Your example uses public inheritance which models an "is-a" relationship. So, if you have objects that meet this criteria, but have the

I am programming a game in java, and as the question title suggestions i am using public fields in my classes. (for the time being) From what i have seen public fields are bad and i have some understanding why. (but if someone could clarify why you should not use them, that would be appreciated) The thing is that also from what i have seen, (and it seems logical) is that using private fields, but using getters and setters to access them is also not good as it defeats the point of using private fields in the first place. So, my question is, what are the alternatives? or do i really have to use

I'm constructing a method to take in an ArrayList(presumably full of objects) and then list all the fields(and their values) for each object in the ArrayList. Currently my code is as follows: public static void ListArrayListMembers(ArrayList list) { foreach (Object obj in list) { Type type = obj.GetType(); string field = type.GetFields().ToString(); Console.WriteLine(field); } } Of course, I understand the immediate issue with this code: if it worked it'd only print one field per object in the ArrayList. I'll fix this later - right now I'm just curious how to get all of the public fields

I have an application that saves files downloaded from a server. These files are not private to my application and should be accessible to other applications as well. I want to know what would be the correct path to save these files when the SD card is ABSENT. For the SD card, there is the well known API - getExternalStorageDirectory() For the application's private data in the internal memory there is - Context.getFilesDir() On some devices, the internal memory is represented by /emmc/. It will be really helpful if someone could elaborate on /emmc/. I know it stands for embedded Memory card

I need to map the ports on the host to the ports on the container. I can achieve this by running the "docker run" command with the -p option. How do I achieve this through the Dockerfile ? Using the following gives a "deprecated error" EXPOSE 80:8080 How else can I make the exposed ports public through teh dockerfile? You can't. What ports are published on the docker host is strictly a decision that should be made by the local administrator, not by the image they are trying to run; this would be (a) a security problem (hey, I just opened up ssh access to your system!) and (b) prone to failure

I recently tried to setup git repo on a linux box and wasted about 10 hours with absolutely no results. There aren't any problems with compilation or anything like that, it's just configuration issue. 2 hours later I got mercurial to do everything i need: public repos web ui push/pull with per-user permissions (not tied to linux accounts) Everything that I can see about git assumes that you are either just running it locally, using github or already have everything setup. I'm either not looking for the right keywords or there just no or very little info on the subject. I do want to try git,
