NET, J etc. There are two ways of compiling the above C Program. If you write this Program in Visual Studio's. The IDE internally complies and executes the application without any user interaction. In this method we manually compile and execute the above application using the Command Prompt.
You can compile the program by simply using the C compiler Tool csc. Csc FirstCSProgram. Now type "FirstCSProgram. Note: cs is the file extension for C applications. Important point: Before using the tools such as csc. To set these environmental variables, you have two choices; first, you can run a batch file named vcvars So you can directly use the.
NET tools here. In the above statement, system is the namespace and we are importing it into our program. I will explain what this namespace is and how to use it and its importance in our next session; for now just remember that a namespace is a group of similar types of items and every class should belong to a specific namespace. Line 2: Our next line in our program defines a namespace to our class as shown below: namespace sai.
When the compiler encounters this opening brace it will crease a new space on the stack memory where it will declare the variable which is scoped to that block only in the next chapter I will explain about variables, declaring variables and their scopes and allocating some memory from that newly created space for that block.
Like when the compiler maintains n number of variables in memory. Line 4: In line 4 of our program we are declaring the class and its name as shown below: class FirstCSProgram In C programming, whatever the business logic is that you want to write, it should be in a class block. I will explain what a lass is and its uses in our future chapters so don't worry abou that; for now just remember that whatever you want to write should be written in a class block and every program should contain at least one class.
A class optionally contains variables and optionally methods or functions; here we can define a class by simply writing a user-defined class name preceded with the "class" keyword. Line 6: As I said in the above line, that is a class optionally containing variables and optionally containing methods or functions; here now in line 6 we defined a function or method as shown below: static void Main One important point you should note is that a program can contain multiple classes under one namespace but in that class at least one class should contain this Main method because the compiler starts its job from this Main function; if you do not have this function in your program then the compiler cannot compile your program because it doesn't know from where it should start compiling and instead just raises an error.
So you can define a Main method as we defined in our program. Note: A deep discussion on this Main method and their uses will be in future chapters. Line 8: This is the first statement in our Main method. Note that every statement should end with a semicolon ;.
This detailed guide will help you to crack your Job interview for ASP. Currently there is ASP. NET 4. There are various page extensions provided by Microsoft that are being used for web site development. Eg: aspx, asmx, ascx, ashx, cs, vb , html, XML etc.
What is the difference between Server. Transfer and Response. In Server. This provides a faster response with a little less overhead on the server. The clients url history list or current url Server does not update in case of Server.
Which validator control you use if you need to make sure the values in two different controls matched? ViewState is stored in a hidden field on the page at client side. ViewState is transported to the client and back to the server, and is not stored on the server or any other external source.
What are the different Session state management options available in ASP. Out-of-Process Session state management stores data in an external server. All objects stored in session are required to be serializable for Out-of-Process state management. How you can add an event handler? Caching is a technique used to increase performance by keeping frequently accessed data or files in memory. Which type if caching will be used if we want to cache the portion of a page instead of whole page?
Fragment Caching: It caches the portion of the page generated by the request. For that, we can create user controls with the below code:. Is it possible to create web application with both webforms and mvc? We have to include below mvc assembly references in the web forms application to create hybrid application.
It is a feature used to secure connection string information. Write code to send e-mail from an ASP. NET application? What is the good practice to implement validations in aspx page? All URL requests are based on controllers and actions. If any other URL request is given it shows an error like the below screen shots.
You can learn many concepts from MVC default application. MVC 5 is available in Visual Studio and above. Conclusion MVC support responsive websites with the help of bootstrap. It is the default available in MVC 4 and above. You can learn advanced concepts of MVC in a future article. View All. Basics Of ASP. Vignesh Mani Updated date Feb 07, A separation of concern is a main advantage of MVC.
It means we can divide into three part of the application like Model, View and Controller. Handles the code easily because of separation of concern. In the same time we can split many developers' work at one time. It will not affect one developer's work to another developer's work.
It supports TTD test-driven development. We can create an application with unit test. We can write one test case. Latest version of MVC supports default responsive web site and mobile templates. We can create our own view engine.
