Purpose: – Illustrates the for .




Step 1: Click on C# to Cut-n-paste code into clsJoin.cs

using System;
public class clsJoin
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Example #1: 	Join(SourceArray(), Delimiter)
        // Returns a string created by joining a number of substrings contained in an array.
        // SourceArray - One-dimensional array containing substrings to be joined.
        // Delimiter - Optional. Any string, used to separate the substrings in the returned string.
        // If omitted, the space character (" ") is used. 
        // If Delimiter is a zero-length string ("") or Nothing, all items in the list are concatenated 
        // with no delimiters.
        // Return Value - Returns a string created by joining a number of substrings contained in an array.
        //****************************************************************************************
 
        Console.WriteLine("Example #1: 	Join(String(), String) ");
 
        string[] arrayJoinExample = { "Apples", "Oranges", "Strawberries" };
 
        // Return Uppercase
        Console.WriteLine(string.Join("!", arrayJoinExample)); //Returns Apples!Oranges!Strawberries
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
 
}

Step 2: Click on C# to Cut-n-paste code into Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            clsJoin myJoin = new clsJoin();
            myJoin.Main();
 
        }
    }
}

Prerequistes:

  1. Install C# (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

Notes:

  • Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
  • You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Program.cs

Joinuctions:

  1. Use C# 2010 Express or Standard Edition
  2. Create new project;
    • Click File/New Project
    • Select Console Application Template
    • Select C# for Language
    • name of project could be CSharp_Syntax.
  3. CS Syntax File Directory Binary File Read Sequential

  4. Add New folder named “StringManipulation”
    • Right-click project name in solution explorer;
    • add new folder;
    • name of folder could be: StringManipulation
  5. Add Class Named clsJoin to StringManipulation folder
    • Right-click StringManipulation folder;
    • add new item;
    • Select class
    • Class name could be clsJoin
  6. Click on C# in code in step 1 at top of page to copy code into clsJoin.cs
  7. Click on C# in step 2 at top of page to copy code into Program.cs
  8. Click green arrow or press F5 to run program
