The data type of a variable is determined by the. NET types of the values of the variable. To view a variable's object type, use Get-Member. You can use a type attribute and cast notation to ensure that a variable can contain only specific object types or objects that can be converted to that type. If you try to assign a value of another type, PowerShell tries to convert the value to its type. If the type can't be converted, the assignment statement fails.

To use cast notation, enter a type name, enclosed in brackets, before the variable name on the left side of the assignment statement. If the variable name and dollar sign aren't enclosed in quotation marks, or if they're enclosed in double quotation " marks, the value of the variable is used in the command or expression. If the variable name and dollar sign are enclosed in single quotation ' marks, the variable name is used in the expression.
