Newline character literal in ASP.Net (C# & VB.Net)

Sometime we come across the scenarios where we need to break the string in the middle. In this tutorial you will learn how to do this.

Suppose you have a string in your page load event as follows:

C#

protected void Page_Load(object sender, EventArgs e)
{
    string strText = "First line Second line Third line Fourth line";
    Response.Write(strText);
}

VB.Net

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
    Dim strText As String = "First line Second line Third line Fourth line"
    Response.Write(strText)
End Sub

When you run this code, the output will be as follows:

Assume that you want to break this string at some specific length. You can do it by simply modifying the above code as follows:

Add New Line Literal "\n" and Carriage Return Literal "\r" at the point where you want to break the string and replace those literals with breakline "<br />"

C#

protected void Page_Load(object sender, EventArgs e)
{
    string strText = "First line\r\n Second line\r\n Third line\r\n Fourth line";
    strText = strText.Replace("\r\n", "<br />").Replace("\r", "<br />") ;
    Response.Write(strText);
}

VB.Net

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
    Dim strText As String = "First line\n\r Second line\n\r Third line\n\r Fourth line"
    strText = strText.Replace("\n\r", "<br />").Replace("\r", "<br />")
    Response.Write(strText)
End Sub

When you run this code, the output will be as follows:
