arrrowOpen Tool Box  (view  menu  Tool Box)

arrrowPlace a button on the form

arrrowCode for button click event

Private void button1_ click

{

Message Box. Show  ( Int. Max value . To String ());

Message Box. Show  ( Int. Min value . To String ());

}

Output

Execute the project

 

Write line () is used to display a message in Console Application.

Example on Parsing

 

Screenshot_18

Open window forms application project

Place two text boxes and a button

Code for button 1 click

Note 

The value  typed in text box 1 as called as text box1 .text

Button1 arrrowClick here

 

Message box. Show  (text box 1. Text  + text box 2. Text);

Int Sal = int. parse  (text box 1. Text);

Int inc  =  int. parse  (text box 2. Text);

Int total = sal + inc;

Message Box. Show (total . to string ());

(or)

Message Box. Show (total + “”);

Execute the project

Observations

In C # , message Box . Show () is  capable to point only string

‘+’ operator is used to add numbers and to concatenate string.

10 + 20 = 30

“10” + “20” = 1020

“10” + 20 = 1020
