Chapter 12: Customizing the Development Environment 363
You’ve now recorded a macro. To check the preceding steps against what you’ve
produced, here’s a revised AddNewCustomer method, showing what the results should
look like:
C#:
using System;
class Customer
{
public int AddNewCustomer(string firstName, string lastName)
{
if (string.IsNullOrWhiteSpace(firstName))
{
throw new ArgumentNullException(
"firstName",
"firstName value is not valid.");
}
int newCustID = 0;
// Logic to add customer
return newCustID;
}
}
VB:
Public Class Customer
Function AddNewCustomer(
ByVal firstName As String,
ByVal lastName As String) As Integer
If String.IsNullOrWhiteSpace(firstName) Then
Throw New ArgumentNullException(
"firstName",
"firstName value is not valid.")
End If
Dim newCustID As Integer = 0
' Logic to add customer
Return newCustID
End Function
End Class
