You can use the following methods in PowerShell to convert a hash table to a string:
Method 1: Convert Hash Table Keys to String
[string[]]$keys_string = $employees.Keys
This particular example converts all of the keys in the hash table named $employees to a string.
Method 2: Convert Hash Table Values to String
[string[]]$values_string = $employees.Values
This particular example converts all of the values in the hash table named $employees to a string.
Method 3: Convert Hash Table Elements to String
[string[]]$elements_string = ($employees | Out-String -Stream) -ne '' | Select -Skip 2
This particular example converts all of the elements in the hash table named $employees to a string.
The following examples show how to use each method in practice with the following hash table named $employees:
$employees = @{
A0001 = 'Andy';
A0002 = 'Bob';
A0003 = 'Chad';
A0004 = 'Derrick';
A0005 = 'Erin';
A0006 = 'Frank';
A0007 = 'Greg';
}
Example 1: Convert Hash Table Keys to String
We can use the following syntax to convert only the hash table keys to a string:
[string[]]$keys_string = $employees.Keys
The following screenshot shows how to use this syntax in practice:
Notice that all of the keys from the hash table have been converted into a single string named $keys_string.
Note: You can verify that $keys_string is indeed a string by typing $keys_string.GetType().
Example 2: Convert Hash Table Values to String
We can use the following syntax to convert only the hash table values to a string:
[string[]]$values_string = $employees.Values
The following screenshot shows how to use this syntax in practice:
Notice that all of the values from the hash table have been converted into a single string named $values_string.
Example 3: Convert Hash Table Elements to String
We can use the following syntax to convert all of the hash table elements to a string:
[string[]]$elements_string = ($employees | Out-String -Stream) -ne '' | Select -Skip 2
The following screenshot shows how to use this syntax in practice:
Notice that all of the elements from the hash table have been converted into a single string named $elements_string.
