HostProtectionAttribute.ExternalThreading Property

Definition

Gets or sets a value indicating whether external threading is exposed.

public bool ExternalThreading { get; set; }

Property Value

true if external threading is exposed; otherwise, false. The default is false.

Examples

The following code example illustrates the use of the HostProtectionAttribute attribute with the ExternalThreading property. This example is part of a larger example provided for the HostProtectionAttribute class.

// Use the enumeration flags to indicate that this method exposes 
// synchronization and external threading.
[HostProtectionAttribute(Synchronization=true, ExternalThreading=true)]
private static void StartThread()
{
    Thread t = new Thread(new ThreadStart(WatchFileEvents));
    
    // Start the new thread. On a uniprocessor, the thread is not given
    // any processor time until the main thread yields the processor.
    t.Start();
    
    // Give the new thread a chance to execute.
    Thread.Sleep(1000);
}

Remarks

Code that exposes external threading creates or manipulates threads other than its own, which might be harmful to the host.
