I am working on a program that is supposed to run for 3 days checking for pending messages and I want it to skip some of the processing that it does if there are pending messages in the database but I want it to continue to the next day and if there are pending messages on the last day I want the program to exit. The problem is that when I run it in debug mode in VS it starts over from the beginning including the Build process. This is the code that I am using to check for the last day of the run:
intDateCompare = DateTime.Compare(dtDate2, dtDate3);
if (intDateCompare == 0) {
Console.WriteLine("Finished, press <Enter> to quit");
strFinished = Console.ReadLine();
Environment.Exit(1);
}
It does the compare properly and runs the Exit command like expected when I put a breakpoint there but then it starts the Build process again. What am I doing wrong?
Thanks for any suggestions.

static void Main(string[] args)

string name02;
Console.WriteLine("Welcome to Choice RPG! <press enter to start your adventure>");
Console.ReadKey();
Console.WriteLine("Enter your Adventurers name! <press enter to continue>");

Console.WriteLine(name01 + "! come on, you can think of a better name than that can't you? <press enter to continue>");
Console.ReadKey();
Console.WriteLine("Enter your Adventurers name! <press enter to continue>");
name02 = Convert.ToString(Console.ReadLine());
if (name02 == name01)

Console.WriteLine("Now thats more like it!");

This is my first project with programming in general. I am making an RPG game in which you choose your adventure and this is for the user's ingame name.
Everything works up until the if statement (after that the cmd just closes). If anyone has any ideas to fix it please tell me.
Code looks OK to me, try adding:
Console.WriteLine("Press <ENTER> to exit");
Console.Readline();
at the end to see if the message you want to show, actually shows before the application exits and closes. My guess is you are running in Visual Studio, and the message prints, but then the execution window closes so fast you don't see it.
I've got a console app. I prompt the user for input...my code does its thing and at the end tries to print the output back to the user.
Here's how I try to post back the output to the same console window so they can see the results:
Console.WriteLine( "Output: ");
Console.WriteLine(resultMessage);
Problem is my console closes before it shows the resultMessage.
You can use Console.ReadKey(true); it waits for any key press
When you're in VS, you can also press Ctrl and f5 to open your application outside of the debugger.
A consequence of doing so is that your window will stick around when your program is finished saying
Press any key to continue
One more Console.Read...
if (Debugger.IsAttached)
{
Console.Write("Press Enter to exit: ");
Console.ReadLine();
}
I think it will be better in case of using output redirection to file like
ConsoleApp.exe >results.txt
Use Console.ReadKey(); after the output is written to the console.
I am new to programming and as seems to be traditional I tried to create a "hello world" program in C#; however, as soon as I run the program it closes.
This is my code inside:
main()
console.writeline("hello world");
console.writeline("enter name");
console.writeline("where is the frikin console");
It's really annoying and I know it might be something simple for the additional users but how do I keep the window open.
Use Console.ReadLine(); or Console.ReadKey(); at the end of your program to wait for the return key or for any key.
You can build your program and run the exe from the command line, that will allow you to see the output.
If you want the program to remain running then adding the Read() statement is the traditional approach, as others have already said.
If you just want to see it in debugging and do not want or need the read statement then place a breakpoint at the end of the program during a debug session.
It's really quite simple.
After this line of code:
Console.WriteLine("where is the frikin console");
You need to add this:
Console.ReadLine();
That should work.
The reason the console closes is because you told it to write some stuff to the screen, after it has finished writing what you told it to write it simply closes itself all in the fraction of a second. if you add Console.ReadLine, the console will wait for you to input something before closing, like pressing a key on the keyboard.
Try adding Console.Read(). You need to pause execution somehow.
Console.WriteLine("hello world");
Console.WriteLine("enter name");
Console.WriteLine("where is the frikin console");
Console.ReadLine();
Console.ReadLine(); will close the console after you've hit (for example) enter.
Console.ReadKey(); will close the console after the next key-hit
You can read the console-contents with these methods,too
Console.WriteLine("hello world");
Console.WriteLine("enter name");
string name = Console.ReadLine();
Console.WriteLine("Your name is: " + name);
Console.ReadLine();
add below line at the end
Console.ReadLine();
You could use CTRL + F5 which will opens the command line and after execution of your code, it shows Press any key to continue.... This will be handy for you than adding few lines of code additionally.
Use
Console.ReadLine();
in the end of your code. You are having this problem because the program just write the message then it ends, that's why you can't see anything. By adding that line, you keep the program waiting something to be typed and you can read the message. After this, type something to end the program.
The window automatically closes after your program, you need to let it take some input, for example:
Add
Console.ReadLine();
Which takes a line of input (till "\n"). And your program will wait until somebody hit the return key (they can type anything and the program won't close: until you hit the return key. You can type in "hello world back what's up are you ok?" and nothing will happen.)
or
Console.ReadKey();
Which will take a character of input. This will make your program wait for the user to press any key and then closes.
I'm writing a sample console application in VS2008. Now I have a Console.WriteLine() method which displays output on the screen and then there is Console.ReadKey() which waits for the user to end the application.
If I press Enter while the Console.WriteLine() method is displaying then the application exits.
How can I clear the input buffer before the Console.ReadKey() method so that no matter how many times the user presses the Enter button while the data is being displayed, the Console.ReadKey() method should stop the application from exiting?
Unfortunately, there is no built-in method in Console class. But you can do this:
while(Console.KeyAvailable)
Console.ReadKey(false); // skips previous input chars
Console.ReadKey(); // reads a char
Use Console.ReadKey(true) if you don't want to print skipped chars.
