How to split the string

Introduction: Hello friends, in this article i will explain that how we can split the string from a particular word. Here i’ll split the string from the <br/>tag.

Implementation: Create a new website add a page named split.aspx. Drag and drop a label named lbl_display and a button named btn_split from the toolbox at .aspx page.

Code for split.aspx page:

<form id="form1" runat="server">

    <div>

        <asp:Button ID="btn_split" runat="server" Text="Show Data"

            onclick="btn_split_Click" /><br />

        <asp:Label ID="lbl_display" runat="server" Text=""></asp:Label>

    </div>

    </form>

Code for gridview.aspx.cs page:

using System;

using System.Collections;

using System.Configuration;

using System.Data;

using System.Linq;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Xml.Linq;

using System.Text;

public partial class split : System.Web.UI.Page

{

    // here m declaring StringBuilder

    StringBuilder str_split = new StringBuilder();

    // These variable are for print solution in  next line

    string[] parts1;

    string[] parts2;

    string output;

    string input;

    Int32 k;

    Int32 j;

    protected void Page_Load(object sender, EventArgs e)

    {

        if (Page.IsPostBack == false)

        {

            // here i am addding the data inside in stringbuilder

            str_split.Append(@"Lorem Ipsum is simply dummy text of the printing and typesetting industry.<br/>

            Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, <br/>

            when an unknown printer took a galley of type and scrambled it to make a type specimen book.<br/>

            It has survived not only five centuries, but also the leap into electronic typesetting,

            remaining essentially unchanged.<br/>

            It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, <br/>

            and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.");

            // here here m adding  the stringbulder's data inside the input sting

            input = str_split.ToString();

            // here i am splitting the data after every <br/>

            parts1 = input.Split(new string[] { "<br/>" }, StringSplitOptions.None);

            // here i am using for loop to insert the data inside the  ViewState["parts"]

            //from the array  parts1 and add <br/> after every line

            for (k = 0; k < 6; k++)

            {

                ViewState["parts"] += (parts1[k] + "<br/>");

            }

            // here m using a viewstate to displaying the the data after clicking the button

            ViewState["value"] = 0;

        }

    }

    protected void btn_split_Click(object sender, EventArgs e)

    {

       // here m emptying the label after every click

        lbl_display.Text = string.Empty;

        //  // here here m adding  the ViewState's data inside the output sting

        output = ViewState["parts"].ToString();

        // here i am splitting the data after every <br/>

        parts2 = output.Split(new string[] { "<br/>" }, StringSplitOptions.None);

        Int32 j;

        // here m using the for loop to display the data step by step inside teh label

        for (j = 0; j <= Convert.ToInt32(ViewState["value"]); j++)

        {

            lbl_display.Text += (parts2[j] + "<br/>");

        }

        // when all line will be printed then the below condition will be satisfaies.

        // and the code will enter inside this condition

        if (Convert.ToInt32(ViewState["value"]) == 6)

        {

            // here m disabling the button after printing all the line

            btn_split.Enabled = false;

          

            //ViewState["value"]= "";

            return;

        }

        // here m incrementing in the viewstate with 1 everytime

        ViewState["value"] = Convert.ToInt32(ViewState["value"]) + 1;

      

    }

}

Below i am displaying the output of this program in the image after first click:

Below i am displaying the output of this program in the image after second click:

Below i am displaying the output of this program in the image after third click:

Below i am displaying the output of this program in the image after fourth click:

Below i am displaying the output of this program in the image after fifth click:

Below i am displaying the output of this program in the image after sixth click:

After sixth click of the button, button will be disable because after sixth click all the complete six lines will be display with the label on your screen.

Conclusion: Dear friends, through this article you have learned that how we can split the string.
