Exitin the program

Question

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 { .... .... } }

Normal 0 Hi You had written that code inside the constructor. Write that code inside the page load then it will work fine. Normal 0 private void Form1_Load( object sender EventArgs e) { string str = Normal 0 getString() ; if (str ==  ) { MessageBox .Show( string is empty ); Application .Exit(); } } Happy Coding!!
