Hi,

We will be using this method
System.IO.Path.GetTempFileName()
to generate around 200 files inside a function. May I know how can we ensure that the file name are not repeated so that will will not be overwrite?

Please advice.

Hi,
According to Microsoft it manages the file name uniquely for u
http://msdn.microsoft.com/en-us/library/system.io.path.gettempfilename(vs.71).aspx
What u can do to make sure there are no duplications is either test if there is a file already with that name in th folder using file.exists function, or on the return string from function GetTempFileName() - u can then save the file and adjust the file name and add at the end for examle the hour/minute/second/millisecond paramter to make sure the names are different to each file (HH:mm:ss mm )
 hope this helps

hi ,
try this

string fileName = System.IO.Path.GetTempPath() + Guid.NewGuid().ToString()
