How to dispose an object created by FileInfo class

Question

I am using a FileInfo class to get the length of the file as follows: FileInfo infoFile = new FileInfo(configFile); long configFileLength = infoFile.Length; here configFile is the path of the file. I want to dispose the object infoFile. How can i do this?

You can't because the FileInfo class doesn't implement IDisposable or need to. It just takes a snap-shot of a file's properties and doesn't retain a handle on the underlying unmanaged resource. However you might be able to accelerate the time when it's garbage collected by setting the object reference to null when it's no longer needed: infoFile = null;
