Hey Guys


I'm a first time poster and fairly new to .NET, though I'm an experienced programmer (java, perl, C++). I'm writing a small application in VB.NET and I wanted to loop trough a Hashtable and while looping trough the keys change values.

Some example code

Dim myHash As Hashtable = New Hashtable
myHash.Add("key1", "value1")
myHash.Add("key2", "value2")
myHash.Add("key3", "value3")

Dim en As IDictionaryEnumerator = myHash.GetEnumerator
While (en.MoveNext)
myHash(en.Key) = "changed"
End While

Now this throws the exception that the collection was modified while looping trough it. Which is true ofcourse. The problem is that I can't just itterate through the keys only, the collection contains both keys and values even if I use myHash.Keys.GetEnumerator it still won't work.

So my question is how to loop through the key values only of this collection so that the compiler doesn't object to changing values ?

regards

Seth
