SMOEnumerator.Current Property

public:
 property System::Object ^ Current { System::Object ^ get(); };

public object Current { get; }

member this.Current : obj

Public ReadOnly Property Current As Object

Property Value

An object that is the current object in the collection.

Implements

Examples

The following code example creates a ForEachLoop, creates a SMO enumerator and hosts it in a ForEachEnumeratorHost, where it is then added as the ForEachEnumerator in the ForEachLoop. Returning a ForEachSMOEnumerator, a SMOEnumerator is created as a System.Collections.IEnumerator and iterated over using MoveNext and Current. After the collection has passed the end, the Reset is used to reset the iterator.
