Hi All,

 I would like to do a search and replace on a flat file.  i would like to find a wildcard of a string and completely update the line with a new string.

For example my orginal file is:

Jim and Dog

George and Cat

Karen and Rat

Sam and Puppy

I would like the output of the new file.

James

George and Cat

Karen and Rat

Sam and Puppy

Here is my code.

       
        Dim path As String = "C:\river1.txt"

   
        Dim strText As String = File.ReadAllText(path)
        Dim objFile As System.IO.StreamWriter
       

        strText = Replace(strText, "Jim ", "James ")

        objFile = My.Computer.FileSystem.OpenTextFileWriter("C:\river1.txt", False)

        objFile.Write(strText)
        objFile.Close()

Thank you,

Hi,

You can simply do 

Dim regex As Regex = New Regex("^.*Jim.*$", RegexOptions.Multiline)
strText = regex.Replace(strText, "James")

thank you very much.!
