Demonstrates how to seralize / deserialize a Hashtable to/from XML.

Note: This example requires Chilkat v9.5.0.64 or later.

PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

# Note: This example requires Chilkat v9.5.0.64 or later.

# Add some entries to a hashtable.
$hashTab = New-Object Chilkat.Hashtable

$hashTab.AddStr("aaa","111")
$hashTab.AddStr("bbb","222")
$hashTab.AddStr("ccc","333")

# Serialize to XML
$sb = New-Object Chilkat.StringBuilder
$hashTab.ToXmlSb($sb)
$($sb.GetAsString())
$("---")

# The output is as follows.  Each hash table entry
# is contained in an "e" node.  The entry's key
# is in the "k" node, and the value in the "v" node.

# <?xml version="1.0" encoding="utf8-8"?>
# <hashtable>
# <e><k>aaa</k><v>111</v></e>
# <e><k>bbb</k><v>222</v></e>
# <e><k>ccc</k><v>333</v></e>
# </hashtable>
# 

# Now load (deserialize) into a new hash table.
$hashTab2 = New-Object Chilkat.Hashtable
$hashTab2.AddFromXmlSb($sb)

# Get the hash table keys, and lookup each (to show 
# that the hash table was correctly deserialized).
# The GetKeys method can return the keys in any order.
$sTable = New-Object Chilkat.StringTable
$hashTab2.GetKeys($sTable)

$i = 0
$numKeys = $sTable.Count
while ($i -lt $numKeys) {
    $key = $sTable.StringAt($i)
    $($key + ": " + $hashTab2.LookupStr($key))
    $i = $i + 1
