I have loaded a text file's contents into a string variable

e.g.

Title:Mr
Initials:Test
Surname:Test

I need to search through the string for "Initials:" and get the word next to it.

How can I do it?

There are about a billion ways to go about it...

Here's another one:
Dim initials As String = ""
        Dim initialsFound As Boolean = False

        Dim lines() As String = System.IO.File.ReadAllLines("c:\some path\folder\file.ext")
        For Each line As String In lines
            If line.ToLower.StartsWith("initials:") Then
                initials = line.Remove(0, "initials:".Length)
                initialsFound = True
                Exit For
            End If
        Next

        If initialsFound Then
            MessageBox.Show(initials, "Initials")
        End If

Here is another way:

        Dim strText As String = System.IO.File.ReadAllText("C:\folder path\test.txt")
        Dim strSearch As String = "Initials:"
        Dim strFound As String = ""
        If strText.IndexOf(strSearch) > 0 Then
            strFound = strText.Substring(strText.IndexOf(strSearch) + strSearch.Length)
            If strFound.Length > 0 Then
                strFound = strFound.Substring(0, strFound.IndexOf(vbNewLine))
                MessageBox.Show(strFound, "Initials")
            End If
        End If

Hi!

As an alternate, I used Linq to decrease LOC, have a look at this as well:
        Dim contents As New List(Of String)(IO.File.ReadAllLines("C:\abc.txt"))
        Dim keyword As String = contents.Find(Function(c) c.StartsWith("Initials:")).Split(":")(1)
