Exitin the program

Vladimir Ota

I have a piece of code like the one below. It gets a string from somewhere, checks it and if string is empty it should display the message and exit the program. The problem is that it doesn't exit but continues. I can not figure out what I'm doing wrong.

public Form1()
{
    InitializeComponent();
   string str=getString();
   if (str=="")
   {
       MessageBox.Show("string is empty")
       Application.Exit();
    }
    .....
    .....
}

I figured that I have to move the code away from the constructor just before I saw your suggestion. But problem persisted. Code after the 'if' statement block still got executed. Then I modified whole thing like below and now it works as expected. Seems to me that I have wrong understanding how exactly the Application.Exit() works. I checked this in MS docs, but I can't say I understand it any better.

Thanks for help anyway!

private void Form1_Load(object sender, EventArgs e)
{
     string str = getString();
     if (str == "")
     {
          MessageBox.Show("string is empty");
          Application.Exit();
     }
     else
     {
         ....
         ....
     }
}

Hi,
    You had written that code inside the constructor. Write that code inside the page load then it will work fine.

private void Form1_Load(object sender, EventArgs e)

{

     string str = getString();

     if (str == "")

     {

          MessageBox.Show("string is empty");

          Application.Exit();

     }
}

Happy Coding!!
