Ho do I clear all items in a dictionary?

Hi All,

 

I am asking a question similar to the one already answered in the question: "How do I clear a DataTable in a Workflow?". I have a system.collections.generic.idictionary<string,FeatureSet>. I want to clear. Since there is no activity that does this I figured the way to go is to use activity Invoke Method .Clear() on the idictionary. Logical but no go. I get an error of "IDictionary`2'  does not have a public instance method named 'Clear' matching the parameter types, generic type arguments, and generic type constraints supplied to InvokeMethod 'InvokeMethod'.

 

TargetType = null, TargetObject = the specfied idictionary, MethodName = Clear, GenericTypeArguements = null, Parameters = null.

 

What am I missing here? Anyone know a better way to clear out a dictionary without deleting it and recreating it?

 

Thanks,

 

Wiley

  Also , if this helps, the dictionary is created in the Variables as "new Dictionary (of string, featureset)" with variable type of System.Collections.Generic.IDictionary<String,FeatureSet>

  Figured it out, I used ClearCollection activity. The type argument is KeyValyePair<String.FeatureSet>.
