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.
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]);
I don t know if I m understanding your question correctly, but couldn t you just use this?
myHashtable[key]
I recommend you to use Dictionary instead of Hashtable as it is a typed Hashtable. For data retreivale
if(myHahtable.ContainsKey(key))
object value = myHahtable[key];
