C# Windows Forms

Here we go with some basics concepts of C# Windows Forms.

Step 1:- Go to File->New->Project

Step 2:- Select your language C# and Windows Forms Application in template

 

Now press on the OK. You can see the your C# Window Form. This is your first form. On the Left of the visual studio you can see the toolbar which contain tools. In the next blog we will see How to add controls in our C# forms and how we can use them In the next blog we also study about solution explorer, toolbar.

Now above you can see C# Windows Form. To execute that project either press F5, or click

Debug -> Start Debugging.

C# Console Output

C# Console Output

This blog will give insight of C# Console output

Console.Writeline("");

Whatever is written in the small parentheses between the double quotes will be written on to the Console screen at time of execution
Example of C# Console output CILCK HERE.

C# Console Input

Get input from user in C# Console

we are going to take a look some concepts how we can get the data from the user in C# console application.

We already used these concepts in our previous applications.

Like C# Console Calculator its uses the concept of C# console input.

Console Calculator

Console Application

In the previous blog we saw about sum of two number to see it again CLICK HERE
Now If you want to make console program for subtraction or multiplication then you have to only change the  operator in the previous program.

Now We are going to see how we can make a calculator in Console.

Requirements:-1 User will provide the two numbers on which action to be performed.

2. After it User will select what action(Subtraction,addition,multiplication or division) user want to perform.

Sol:- Write this code .

                Console.WriteLine("**** Enter the first number *****");
                int x = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("**** Enter the second number *****");
                int y = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("**** Enter 1 for addition  *****");
                Console.WriteLine("**** Enter 2 for subtration  *****");
                Console.WriteLine("**** Enter 3 for multification  *****");
                Console.WriteLine("**** Enter 4 for divition  *****");
                int z = Convert.ToInt32(Console.ReadLine());
                switch (z)
                {
                    case 1:
                        Console.WriteLine(x + y);
                        break;
                    case 2:
                        Console.WriteLine(x - y);
                        break;
                    case 3:
                        Console.WriteLine(x * y);
                        break;
                    case 4:
                        Console.WriteLine(x / y);
                        break;
                }

Console Readline

Console Programs

Here we are going to learn how to make some console program. In the previous blog we studied about how to make a very short console program.CLICK HERE to see it again. Now we are going to discuss some concepts of previous console program.

       We have seen Console.WriteLine() method. In it Console is a class and "WriteLine" is an method of that class. So we have a clear concept to how to write in the console but if we want a program which calculate the sum of two  number then how we can do that?

            How we can read the number from Console? There is lot methods but here we are going to use Console.ReadLine() method. We will use like

int x = Console.Readline();

NO!! the above syntex genrate an error because it return the value in the form of string so we need to convert the string value to the int value and How we shall do that?

int x = Convert.ToInt32(Console.ReadLine());

CONSOLE PROGRAM:-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Enter the first number!");
            int x = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter the second number!");
            int y = Convert.ToInt32(Console.ReadLine());
            int z = x + y;
            Console.WriteLine("Result of the sum is");
            Console.WriteLine(z);
           
        }
    }
}
