为什么我的控制台应用程序立即消失

Question

I've made a Console Application is Microsoft Visual Studio 2012. This is what i've added to my code.

    static void Main(string[] args)
    {
        Console.WriteLine("Hello World");
    }

When I'm debugging this program, the program close immediatly! What am I doing wrong?

Answer 1

您必须将Console.ReadLine()添加到Main方法的末尾，这将使控制台等待，直到用户将任何输入发送到控制台，然后它将退出。

Answer 2

Al the existing answers are correct, but Ctrl-F5 (instead of just F5 in VS) to run will also have the effect of waiting for a keystroke.

EDIT

The above will not allow you to debug as such, but you don't have a breakpoint in there anyway. Pressing F10 will step through the program line by line.

Answer 3

you have to write the

Console.WriteLine("Hello World");
Console.ReadLine();

Answer 4

Because the only statement you have just prints a line and the execution of program is finished and program is exited. Use Console.ReadLine Line to stop window to get disappear. Use read line will exit program when Enter key is pressed.

You can use ReadKey if you want to do like "Press any key to continue..." The will cause the program to exit when any key is pressed.

static void Main(string[] args)
{
    Console.WriteLine("Hello World");
    Console.Read();
}

Answer 5

You should add Console.ReadLine(); after WriteLine method, So your application will wait user to input. After user pressed any keys, Your application will disappear.

   static void Main(string[] args)
    {
        Console.WriteLine("Hello World");
        Console.ReadLine();
    }

Answer 6

You could just add

Console.ReadKey();

This will await a keystroke before closing the program.

Answer 7

all of the above is correct. Typically, Console.ReadKey() is used for control purpose instead logic processing.

static void Main(string[] args)
{
    Console.WriteLine("Hello World");
    string line = Console.ReadKey();
}
