Writing Macros
When the productivity features that ship with VS and custom snippets don’t give you
enough power, the next step is to consider creating a macro, which is a repeatable set of
actions that you can record and re-run multiple times. An example of when a macro is
useful is whenever you find yourself continuously repeating the same set of actions in VS.
This section will show you how to create and run a macro that uses VS features to create a
customized block of code for validating strings.
Recording a Macro
When creating business objects, it’s common to validate input parameters to ensure they
are valid. One such validation is enforcing that calling code pass a required parameter.
The example in this section shows you how to write a macro for validating that a string-
type parameter is not null, empty, or white space (such as a space or tab). To get started,
create a new Console project and add a Class file with the following method to the project,
which simulates adding a new customer:
C#:
using System;
class Customer
{
public int AddNewCustomer(string firstName, string lastName)
{
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
Dim newCustID As Integer = 0
' Logic to add customer
