StringEnumerator::Current Property

Gets the current element in the collection.

Namespace:  System.Collections.Specialized
Assembly:  System (in System.dll)

public:
property String^ Current {
	String^ get ();
}

Property Value

Type: System::String
The current element in the collection.

ExceptionCondition
InvalidOperationException

The enumerator is positioned before the first element of the collection or after the last element.

After an enumerator is created or after a Reset is called, MoveNext must be called to advance the enumerator to the first element of the collection before reading the value of Current; otherwise, Current is undefined.

Current also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.

Current does not move the position of the enumerator, and consecutive calls to Current return the same object until either MoveNext or Reset is called.

An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated and the next call to MoveNext or Reset throws an InvalidOperationException. If the collection is modified between MoveNext and Current, Current returns the element that it is set to, even if the enumerator is already invalidated.

The following code example demonstrates several of the properties and methods of StringEnumerator.

#using <System.dll>

using namespace System;
using namespace System::Collections::Specialized;
int main()
{

   // Creates and initializes a StringCollection.
   StringCollection^ myCol = gcnew StringCollection;
   array<String^>^myArr = {"red","orange","yellow","green","blue","indigo","violet"};
   myCol->AddRange( myArr );

   // Enumerates the elements in the StringCollection.
   StringEnumerator^ myEnumerator = myCol->GetEnumerator();
   while ( myEnumerator->MoveNext() )
      Console::WriteLine( "{0}", myEnumerator->Current );

   Console::WriteLine();

   // Resets the enumerator and displays the first element again.
   myEnumerator->Reset();
   if ( myEnumerator->MoveNext() )
      Console::WriteLine( "The first element is {0}.", myEnumerator->Current );
}

/*
This code produces the following output.

red
orange
yellow
green
blue
indigo
violet

The first element is red.
