Re: How to loop through Hashtable keys without using foreach

The problem isn't the foreach but how you're using the data. You're
looping through the keys and then again looking up each value by key
which is waisteful. Instead do this:
foreach(DictionaryEntry de in ht) {
this.setProperty(de.Key, de.Value);
}
You may need some casting depending on how setProperty is declared.
In general you don't want to replace for-each loops with indexed
loops.

I noticed that using foreach is much slower than using for-loop, so I
want to change our current code from foreach to for-loop.
But I can't figure out how.
Could someone help me please?
Current code is here:
foreach ( string propertyName in ht.Keys )
{
this.setProperty( propertyName, ht[propertyName] );
}
