Represents a method that handles general events.

.NET This type appears as System.EventHandler<TEventArgs>.

/// [Windows.Foundation.Metadata.ContractVersion(Windows.Foundation.FoundationContract, 65536)]

template <typename T>
class EventHandler : MulticastDelegate
[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.Foundation.FoundationContract), 65536)]

Remarks

When programming with .NET, this class is hidden and developers should use the System.EventHandler<TEventArgs> class. Existing Windows Runtime events have an event data type constraint for TEventArgs, so use that event-data type if you need the event data in your specific handler implementation.
