C# Join Example Syntax | C-Sharp Join | Source Code
Purpose: – Illustrates the C# Syntax for Join.
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:
- Install C# (Express or Standard Edition)
- Install SQL Server Express
- Download Northwind and pubs Database
- Attach Northwind Database to Databases in Sql Express
- 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:
- Use C# 2010 Express or Standard Edition
