public ref class FileSystemEventArgs : public EventArgs

The FileSystemEventArgs type exposes the following members.

Public methodFileSystemEventArgsInitializes a new instance of the FileSystemEventArgs class.

Public propertyChangeTypeGets the type of directory event that occurred.
Public propertyFullPathGets the fully qualifed path of the affected file or directory.
Public propertyNameGets the name of the affected file or directory.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The FileSystemEventArgs class is passed as a parameter to event handlers for these events:

The Changed event occurs when changes are made to the size, system attributes, last write time, last access time, or security permissions in a file or directory in the specified Path of a FileSystemWatcher.

The Created event occurs when a file or directory in the specified Path of a FileSystemWatcher is created.

The Deleted event occurs when a file or directory in the specified Path of a FileSystemWatcher is deleted. For more information, see FileSystemWatcher.

The following example shows how to create a FileSystemWatcher to monitor file changes (creates, deletes, renames, changes) occurring on a disk drive. The example also shows how to properly receive error notifications.
