Quickly Replace Data in a String Array using LINQ

Tweet

LINQ is amazingly flexible. Recently, I came across a client requirement where the client wanted to replace all '@' characters in emails with the text [attherate]. Here's how it can be done easily using LINQ. The same can also be done by looping through the array and replacing it, but LINQ gives you a lot of flexibility in filtering the data.

C#

        string[] emails = { "Shakiy@gmail.com", "Mary@hotmail.com", "Glenn@gmail.com", "Hillock@yahoo.com"};

 

        var modEmail = from em in emails

                           select new

                           {

                               EmailID = em,

                               ModifiedEmail = Regex.Replace(em, "[@]", "[attherate]")

                           };

 

        foreach (var mo in modEmail)

        {

            Response.Write(mo.ToString() + "<br/>");

        }

VB.NET

Private emails() As String = {"Shakiy@gmail.com", "Mary@hotmail.com", "Glenn@gmail.com", "Hillock@yahoo.com"}

 

var modEmail = from em in emails ReadOnly Property [New]() As select

                       em, ModifiedEmail = Regex.Replace(em, "[@]", "[attherate]")

                       EmailID = em, ModifiedEmail

End Property

 

For Each mo In modEmail

    Response.Write(mo.ToString() & "<br/>")

Next mo
