Question

I know the value of key for my Hashtable,
from key how can I obtain the object of DictinaryEntry.

I don’t want to Iterate over Hashtable.

Answer 1

Although DictionaryEntry is the type returned when you iterate a Hashtable, it’s not really true that a Hashtable ‘contains’ DictionaryEntrys. DictionaryEntry is a value type and so doesn’t have an identity. If you want ‘a’ DictionaryEntry containing a given key and the matching value, you can make one yourself:

DictionaryEntry de = new DictionaryEntry(key, myHashtable[key]);
