int itemIndex = -1;
if ( collection->Contains( testDeclaration ) )
   itemIndex = collection->IndexOf( testDeclaration );

// Tests for the presence of a CodeTypeDeclaration in the
// collection, and retrieves its index if it is found.
CodeTypeDeclaration testDeclaration = new CodeTypeDeclaration("TestType");
int itemIndex = -1;
if( collection.Contains( testDeclaration ) )

' collection, and retrieves its index if it is found.
