In this article, I will explain how to use PowerShell GetType() to get the data type of variable.

PowerShell GetType Examples

PowerShell GetType method gets the current data type of a variable. Let’s understand getType() method with an examples.

Let’s consider an example to assign a company name in a variable as given below

$curDate 
$curDate.GetType()

In the above example, the $curDate variable holds the Get-Date value. Using the GetType method over variable returns the DateTime variable type.
