PS C:\Users\Hind> $b=@{} PS C:\Users\Hind> $b+={k="a";v="b"} A hash table can only be added to another hash table. At line:1 char:1 + $b+={k="a";v="b"} + ~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (:) [], RuntimeException + FullyQualifiedErrorId : AddHashTableToNonHashTable |
Why did it fail? How can I add one element to a hashtable successfully?
Answer:
Correction, this fails because you are missing the @ character in front of @{k="a";b="b"}

@{} is declaring a new hash table. {} is a script block. They are not the same.
