FileSystemWatcher.WaitForChanged Method

Definition

A synchronous method that returns a structure that contains specific information on the change that occurred.

Overloads

WaitForChanged(WatcherChangeTypes)

A synchronous method that returns a structure that contains specific information on the change that occurred, given the type of change you want to monitor.

WaitForChanged(WatcherChangeTypes, Int32)

A synchronous method that returns a structure that contains specific information on the change that occurred, given the type of change you want to monitor and the time (in milliseconds) to wait before timing out.

WaitForChanged(WatcherChangeTypes)

A synchronous method that returns a structure that contains specific information on the change that occurred, given the type of change you want to monitor.

public:
 System::IO::WaitForChangedResult WaitForChanged(System::IO::WatcherChangeTypes changeType);
public System.IO.WaitForChangedResult WaitForChanged (System.IO.WatcherChangeTypes changeType);
member this.WaitForChanged : System.IO.WatcherChangeTypes -> System.IO.WaitForChangedResult
Public Function WaitForChanged (changeType As WatcherChangeTypes) As WaitForChangedResult

Parameters

changeType
WatcherChangeTypes

The WatcherChangeTypes to watch for.

Returns

A WaitForChangedResult that contains specific information on the change that occurred.

Remarks

This method waits indefinitely until the first change occurs and then returns. This is the same as using WaitForChanged with the timeout parameter set to -1.

Note

This method allows an event handler to be invoked to respond to file changes even if the EnableRaisingEvents property is set to false.

In some systems, FileSystemWatcher reports changes to files using the short 8.3 file name format. For example, a change to "LongFileName.LongExtension" could be reported as "LongFi~.Lon".

Public Function WaitForChanged (changeType As WatcherChangeTypes, timeout As Integer) As WaitForChangedResult

Parameters

changeType
WatcherChangeTypes

The WatcherChangeTypes to watch for.

timeout
Int32

The time (in milliseconds) to wait before timing out.

A WaitForChangedResult that contains specific information on the change that occurred.
