Read Comma Delimited String line by line for valye - vb.net

Question

I have the following code which takes a file's encrypted contents and decrypts it into a string. This is simply just a comma Delimited string like the following:
Garry, 001, 0006
Ben, 002, 00
I want to check the values in column 0 and 1 match the contents of a textbox, but It has to be on the same row hence why I need to read each row/line. I've got most of it to work, I just dont know how to read the string line by line and check it's columns, could someone help?
My commented code is just pseudo code for what I'm trying to do.
Using TextReader As New IO.StreamReader("C:\Users\Garry\Desktop\test.txt")
Dim EncryptedString As String = TextReader.ReadToEnd
Dim DecryptedString As String = AESD(EncryptedString, Password)
Dim strReader As New StringReader(DecryptedString)
Dim line As String = strReader.ReadLine
'If Line.column(0).contains(txtName.text) AND Line.column(1).contains(txtEnteredKey.text) then
'Else
'Go to next line
'End If
End Using

Answer 1

You can split the string by the , and then compare the columns to your desired value. For example, if I wanted to find Ben in the list, I could do this:
Dim s As String = "Garry, 001, 0006
Ben, 002, 00"
Dim strReader As New StringReader(s)
Dim line = strReader.ReadLine
While String.IsNullOrEmpty(line) = False
Dim parts = line.Split(","c)
If (parts(0).Trim() = "Ben" And parts(1).Trim() = "002") Then
Console.WriteLine("Found ben!")
Exit While
End If
line = strReader.ReadLine
End While
Console.ReadLine()

You could also do:
Dim DecryptedString As String = AESD(System.IO.File.ReadAllText("C:\Users\Garry\Desktop\test.txt"), Password)
Dim values() As String
For Each line As String In DecryptedString.Split(vbCrLf.ToCharArray, StringSplitOptions.RemoveEmptyEntries)
values = line.Split(",")
If values.Length >= 2 AndAlso values(0) = txtName.Text AndAlso values(1) = txtEnteredKey.Text Then
' ... do something ...
Exit For
End If
