Complie Using notepad

Step 1: Open Notepad and write the following c# code carefully.

using System;

namespace Chapter1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("This is my First C# Program");
}
}
}

Step 2: Now save this program as Chapter1.cs. You must choose All Files in save as type box.
Step 3: Go to Start > All Programs > Microsoft Visual Studio 2005 or 2008 > Visual Studio Tools > Visual Studio 2005 or 2008 Command Prompt.
Step 4: Set Path in command prompt where your Chapter1.cs file is saved. Here we are using D:/Csharp>
Step 5: Now compile your program by following command:

csc Chapter1.cs

You will see some information like compiler version number and framework information. There is no error, so you won’t get any error. Step 6: Now, it’s turn to C sharp program. Just write your file name without extension and hit enter.

Chapter1

Step 7: You will get the This is my First C# Program as output.

Write a program to enter a number from 1 to 7 and display the corresponding day of the week. Hint: 1 = Monday ..

using System; class sevenday { public static void Main() { int num1; Console.WriteLine("Enter Number From 1 - 7 to find the correponding day"); num1=Convert.ToInt32(Console.ReadLine()); switch(num1) { case 1: Console.WriteLine(" 1 is Monday"); break; case 2: Console.WriteLine("2 is tuesday"); break; case 3: Console.WriteLine("3 is wednesday"); break; case 4: Console.WriteLine("4 is Thrusday"); break; case 5: Console.WriteLine("5 is friday"); break; case 6: Console.WriteLine("6 is saturday"); break; case 7: Console.WriteLine("7 is sunday"); break; default: Console.WriteLine(" Your Number is Invalid Please Enter Correct Number"); break; } } }

C# Statements

There are various basic things in C# that you need to know. These are very small but too effective. These are called statements in C#. Without covering statements in C#, you can’t be a good programmer. In C# programming, there is various statements as block, empty, goto-label, break, continue, return, throw, checked, unchecked, lock, using etc. These are small but give powerful control you to write your program. List of Contents C# Statements Chapter 1: Block Chapter 2: Empty Chapter 3: Goto-label Chapter 4: Break Chapter 5: Continue Chapter 6: Return Chapter 7: Throw Chapter 8: Checked Chapter 9: Unchecked Chapter 10: Lock Chapter 11: Using Chapter 12: Enumeration Chapter 13: Structure Chapter 14: Examples

C# Enumeration

Enumeration provides efficient way to assign multiple constant integral values to a single variable. Enumeration improves code clarity and makes program easier to maintain. Enumeration in C# also provides more security by better error-checking technology and compiler warnings. An enumeration can be defined using enum keyword. In enumeration, you can define special set of value that can be assigned with enumeration. For Example, you are creating an attendance log application in which a variable can contains value only Monday to Friday. The other value will not be applicable with variables. In order to fulfill this requirement you need to use enumeration that will hold only assigned values and will returns numeric position of values starting with zero. Programming Example of Enumeration (C#) using System; namespace Enumeration { // creating enumeration for storing day. public enum attandance { ...
