Convert VBA Code to C# - How to find a phrase in a string and then parse everything to the left of that value?

Please note the following code looks for a phase/value called (Phone: ) and once it's found in a string grabs all of the text to the left of it and returns the value:

I'm a lot more familiar with VBA than C# and was wondering if someone could help me with the code below that would be it's equivalent.   MID function does a pretty good job of identifying text in a string if you give it a start value and LEFT I know C#'s equivalent is SubString... but if someone could convert the code to actual C# - it would be much appreciated.

I tried http://www.developerfusion.com/tools/convert/vb-to-csharp and they are still stumped and have not returned a reply.  I'm not trying to be guided to articles where I can read up on how to figure it out.  I'm doing other programming stuff - this is just a little nugget that I'm stuck on and would ideally like some code to try and see if it's doing the same thing in Visual C# .NET.  

Thank you in advance.

Public Function NoPhoneNumber(sValue as String)

Dim newvalue As String
Dim i as Integer

For i = 1 to len(sValue)

If len(sValue) > 8 Then

If mid(sValue, i, 9) = "(Phone: )" Then

  newvalue = Left(sValue, i-9)
  Exit For

End if

End if

Next i

NoPhoneNumber = sValue

End Sub

Here is code which should achieve what you are looking for

Public string NoPhoneNumber(string input)
{
   If (input.IndexOf("(Phone: )") == -1)
   {
      return "";
   }
   
   return input.Substring(0, input.Length - input.IndexOf("(Phone: )"));
}

Another one:
        private string NoPhoneNumber(string phone)
        {
            return phone.Contains("(Phone: )") ? phone.Substring(0, phone.IndexOf("(Phone: )")) : "";
        }

Open in new window


That could also be written as:
        private string NoPhoneNumber(string phone)
        {
            int i;
            return (i = phone.IndexOf("(Phone: )")) != -1 ? phone.Substring(0, i) : "";
        }

I have for my string input:  "GE Healthcare - Anesthesia Delivery  (Phone: ) CAD ID: ANE0034"
And  yet the result using your code comes out to :  "GE Healthcare - Anesthesi"

... so Anesthesia Delivery is cut off.

Mike Tomlinson, that code worked but what if I want to trouble shoot each character in the string and see it getting to the point of 9 characters as it moves from the beginning character to the end... that's what the VBA enables me to see.

With the above code, I can't see the result as it goes through the process of finding it.  

I guess the benefit is that it's faster than looping through each character in the string - is that correct?

Sorry about that. Use

Public string NoPhoneNumber(string input)
{
   If (input.IndexOf("(Phone: )") == -1)
   {
      return "";
   }
   
   return input.Substring(0, input.IndexOf("(Phone: )")-1).Trim()
}

Note: I added trim to strip the whitespace. If this was wrong just remove the Trim() function from the call

"I guess the benefit is that it's faster than looping through each character in the string - is that correct?"

I'm not sure what the underlying code for IndexOf actually does.  It might be looping for you.

If you really want to loop, then:
        private string NoPhoneNumber(string phone)
        {
            string lookFor = "(Phone: )";
            if (phone.Length > lookFor.Length)
            {
                for(int i = 1; i <= (phone.Length - lookFor.Length); i++)
                {
                    if (phone.Substring(i, lookFor.Length).Equals(lookFor))
                    {
                        return phone.Substring(0, i);
                    }
                }
            }
            return "";
        }

Appreciate all the replies.   Mike gets more points for taking the time to give me exactly what I wanted but both deserve 'A's.  Thank you sincerely.
