Cannot implicitly convert type 'System.Collections.Specialized.StringCollection' to..

[cjard]

The documentation says:

public System.Windows.Forms.AutoCompleteStringCollection AutoCompleteCustomSource { set; get; }
Member of System.Windows.Forms.TextBox

Summary:
Gets or sets a custom System.Collections.Specialized.StringCollection to use when the System.Windows.Forms.TextBox.AutoCompleteSource property is set to CustomSource.

Returns:
A System.Collections.Specialized.StringCollection to use with System.Windows.Forms.TextBox.AutoCompleteSource.

And when we try to assign a StringCollection:

Cannot implicitly convert type 'System.Collections.Specialized.StringCollection' to 'System.Windows.Forms.AutoCompleteStringCollection'


There is no inheritance hierarchy linking the two types.. So far, I'm clear the autocompletecollection, and adding al lthe strings our of the stringcollection to it. It would have been much nicer if I could have just bound this in the app settings..

Has anyone else encountered this and have a better solution?
