Random Filenames

[Amy]

Does anyone know if thier is anything built in the framework to generate
random filenames?

I have a dataset(hash table) that grows very large. After a certain point a
good portion of the elements will not be used anymore until the end of the
program. In order to conserve memory I wanted to write out the current data
in the hash table to a file.

Any thoughts?

Probably not the best way but in one application i did a while ago i
generated a GUID and used that & the current date/time as a file name.

Amy, you could use a TempFileCollection to create files whose names are
'random'. You could also use the GetTempFileName method off of the Path
class in System.IO. A third option would be to wrap the win32 API
GetTempFileName(). Hope that gives you some ideas to do what you want.

Use System.Guid.NewGuid() method to get a new GUID object.

How did you generate a GUID? I am using DateTime.Now.Ticks as my "GUID" in

one of my applications. Ok for me but not very good :)

You could try Path.GetTempFileName() under System.IO

"Returns a unique temporary file name and creates a zero-byte file by that
name on disk."
