What is my mistake in the following code

bool CloseInitiated = false;

 private void frmDashboard_FormClosing(object sender, FormClosingEventArgs e)
        {           
            if (CloseInitiated)
            {
                Application.ExitThread();
               
                Application.Exit();
            }
DialogResult dialogResult = MessageBox.Show("Are You Sure to Close AppPortal", "Close", MessageBoxButtons.YesNo);
            if (dialogResult == DialogResult.Yes)
            {
                CloseInitiated = true;

            }
            else if (dialogResult == DialogResult.No)
            {                
                e.Cancel = true;
            }
            if (CloseInitiated)
            {
              Process OrderProcess;              
              Process[] processesOrder=Process.GetProcessesByName("Orders");

                  if (processesOrder.Length > 0)
                    {                    
                        OrderProcess = processesOrder[0];
                        OrderProcess.Kill();
                        Application.Exit();
                        Application.ExitThread();
                        CloseInitiated = true;
                    }
             }
        }
