I have some code in a function like this :

	System.Collections.ObjectModel.Collection<Cypher1.FormField> FieldList = SelectedForm.FieldList as System.Collections.ObjectModel.Collection<Cypher1.FormField>;

  	foreach(Cypher1.FormField F in FieldList)
  	{
  	...... process data here ....
  	}

The SelectedForm.Field List is a Collection<FormField>

But this throws the error :

The error of compilation
The error of compilation is found in the 'Report' report:
Cannot convert type 'Reports.Report.SelectedFormBusinessObject.FieldListBusinessObject' to 'System.Collections.ObjectModel.Collection<Cypher1.FormField>' via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion

What am I doing wrong?

I have managed to get this to work.

I had to change this

Code: Select all

System.Collections.ObjectModel.Collection<Cypher1.FormField> FieldList = SelectedForm.FieldList as System.Collections.ObjectModel.Collection<Cypher1.FormField>;

by adding the code .Current to the end of SelectedForm.FieldList like this :

Code: Select all

System.Collections.ObjectModel.Collection<Cypher1.FormField> FieldList = SelectedForm.FieldList.Current as System.Collections.ObjectModel.Collection<Cypher1.FormField>;
