C-Sharp Join Example | ASP.NET C# Join Syntax | Source Code
Purpose: – Here is a Join Example that illustrates the C# Syntax in ASP.NET.
Step 1: Click on C# to Cut-n-paste code into Join.aspx.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; // This example is from http://idealprogrammer.com // It shows how you can use Join syntax in C-Sharp ASP.NET //**************************************************************************************** // 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. //**************************************************************************************** public partial class StringManipulation_Join : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Label1.Text = "Example #1: Join(String(), String) "; string[] arrayJoinExample = { "Apples", "Oranges", "Strawberries" }; Label2.Text = string.Join("!", arrayJoinExample); //Returns Apples!Oranges!Strawberries } } |
Step 2: Click on XML to Cut-n-paste code into Join.aspx
