PowerShell Execution Policy The PowerShell Execution Policy determines whether PowerShell scripts are allowed to run. By default, the Execution Policy is set to Restricted. If you try to run scripts under the Restricted policy, you will get error messages. In this tutorial, you will learn about the execution policies, how to enable execution of PowerShell scripts on machine.

Begin the hash table with an at sign (@). Enclose the hash table in braces ({}). It will create an empty hashtable for you. You can add Data in hashtable using add method. 3. You can also add keys and values to a hashtable when you create it. For example, the following statement creates a hash table with three keys. Use an equal sign (=) to separate each key from its value. Use a semicolon (;) or a line break to separate the key/value pairs. Keys that contains spaces must be enclosed in quotation marks.  Strings as values must be in quotation marks, even if they do not include spaces. If you want to main...

  Array in PowerShell The array is a type of data structure that can be used to  store a collection of items, the collection of items can  be either of the same datatype or different.  The elements in an array can be accessed using  the index. The index of the array usually starts at 0 just  like other programming languages, so to access the first element, use index [0].  Define Array in PowerShell Array in PowerShell can be defined in multiple  ways. To create and initialize an array, assign comma separated multiple values to a variable.  Pass values to variable within bracket  beginning with @ like $var = @() When no data type is specified, PowerShell creates each array as an object array (System.Object[]).      3. We can create array to hold value of specific type also, like below How to access an Array We can refer to an array by using its variable name. To display all the elements in the array, type the arra...
