There are two possible problems:
1) If you have created this as a console application, then it may be that the application runs too quickly for you to see. Add this line at the end of your Main method:
Console.ReadLine();
This will make the software stop until you have pressed the ENTER key. You should be able to see your text now.
2) If you have created this as a WinForms application, then you need to click on the "output" pane in Visual Studio to see the console output. If you can't find it, look on the menu under "View...Output"
"i think you not fully under stand my main problem. i explain it again. i am a new user i am write a program that print a line (this is my first program); no error in the code.after right the program when i am a press a start debugging button program run and show only a simple small screen."
A question: is the "small window" black, or grey?
If it is black: this is a console application. Make sure your Console.WriteLine instruiction is in the Main method in the file "process.cs"
If it is grey: this is a WinForms application: Discard your Console.WriteLine instruction and open the toolbox (From the menu: "View...Toolbox" under "All Windows Forms" drag a button onto your form.
Double click the button and add the following line to your code when it appears:
MessageBox.Open("Hello Pucit009!");
"i am really very thank full to ans me. you near to my problem my problem is second option. that solution is represent the message box. but i am right only a single statement. just like a (hello its my first program)
simply like print in the java code (hello world)
i want to print in c#. and on the form where is the you ask a add button."
OK: what you want is a Console App.
1) Close your solution (Menu: "File...Close solution")
2) Create a new project (Menu: "File...New Project")
3) In the new project dialog, select "Console Application"
4) Give it a sensible name in the "Name:" text box.
5) Press "OK"
Now if you look in "Program.cs" (double click in the Solution explorer on the RHS of your screen) you will find a method called Main which is pretty empty. Put your Console.WriteLine in there (don't forget the Console.ReadLine() at the end!) and when you run that it will be simple text.
