ForEachVariableMappingEnumerator.Current Property

Definition

Gets the current ForEachVariableMapping object from the collection.

public:
 property Microsoft::SqlServer::Dts::Runtime::ForEachVariableMapping ^ Current { Microsoft::SqlServer::Dts::Runtime::ForEachVariableMapping ^ get(); };
public Microsoft.SqlServer.Dts.Runtime.ForEachVariableMapping Current { get; }
member this.Current : Microsoft.SqlServer.Dts.Runtime.ForEachVariableMapping
Public ReadOnly Property Current As ForEachVariableMapping

Property Value

The current element in the collection.

Remarks

After an enumerator is created, or after a call to the Reset method, the MoveNext method must be called to advance the enumerator to the first element of the collection before the enumerator can read the value of the Current property; otherwise, Current is undefined and throws an exception.

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 invalidated and becomes irrecoverable; thus, the next call to MoveNext or Reset throws an InvalidOperationException. However, if the collection is modified between calls to MoveNext and Current, Current returns the element that it is set to, even if the enumerator has been invalidated.
