Summary<\/b>: Ed Wilson, Microsoft Scripting Guy, talks about adding enums to Windows PowerShell 5.0 classes in Windows 10.<\/span><\/p>\n

Microsoft Scripting Guy, Ed Wilson, is here. It is my birthday week…almost. It is the kind of thing that one needs to begin making plans and preparations for. I know that the Scripting Wife, aka Teresa, is busy working to make this birthday week one of the best ever—at least, I hope that is what she is up to.<\/p>\n

The cool thing is that after my birthday week, it will be time for her birthday week, so we take pretty much the entire month of September to celebrate birthdays. Then it is October, and there are a couple of conferences we are going to, and then there is November, and then December. Yep, the last four months of the year are always something special.<\/p>\n

Then there is January and February and March…well, you get the idea. If you are into Windows PowerShell, every day of every month of every year is special—and that is what makes it fun and exciting. In fact, we have been talking to my good friend and Microsoft Evangelist, Blaine Barton, about some way cool stuff for next year in the sunshine state.<\/p>\n

Adding enums<\/h2>\n

The advantage of using an enum with your Windows PowerShell 5.0 class is that you have automatic parameter validation in Windows PowerShell. This is essential for solving the old-fashioned problem of the “garbage in garbage out” maxim of data processing. When applied as a type constraint for a property in a Windows PowerShell class, an enum will generate an error if the value supplied is not a valid enumeration.<\/p>\n
