What is Hash Table in PowerShell?
Hash table in a PowerShell is constructed with the Key-Value combination. Each key has its own value, so to get the value we need to refer the Key. We don’t need numeric indexing like Array to refer values.
This is how the hash table looks like.
Name Value
---- -----
EmpName Charlie
City New York
EmpID 001
In the hash table creation, keys and values are separated with Semi-colons (;). In the above example, EmpName, City and EmpID are referred as keys while Charlie, New York and 001 are their values respectively.
Hash table is the OrderedDictionary, if you check the hash table type, it would be collection of values (System.Object).
