- DesignerRegion
The DesignerRegion to locate within the collection.
Returns
The zero-based index of the first occurrence of region within the collection; otherwise, -1, if region is not in the collection.
Remarks
The IndexOf method determines equality by using the Equals method on the DesignerRegion objects.
The IndexOf method performs a linear search; therefore, the average execution time is proportional to the Count property. Because template region collections are typically small, the performance of the linear search operation is not critical.
