how loop through multiple checkbox in C#

Question

I have 100 checkboxes in a winform. Their names are sequential like checkbox1, checkbox2 etc. I have a submit button in my winform. After clicking the submitting button, it checks, if a checkbox is checked then some value is updated otherwise another value is updated. I have to check 100 checkbox. So i have to loop through the 100 checkbox to check if the checkbox is checked or not.

I know how to check the checkbox

private void sumit_button_Click(object sender, EventArgs e)
{
     if (checkbox1.Checked)
     { 
        //  update 
     }
     else
     {  
        // update another  
     }

     if (checkbox2.Checked)
     {  
        //  update    
     }
     else
     {   
        // update another  
     }

     ......................and so on

} 
        

But how can i do this for 100 checkbox???

Answer 1

foreach (var control in this.Controls) // I guess this is your form
            {
                if (control is CheckBox)
                {
                    if (((CheckBox)control).Checked)
                    {
                        //update
                    }
                    else
                    {
                        //update another
                    }
                }
            }
