I dont know what happened.If I use file class,then I have to load mscorlib.dll.right???
If this is related to your other thread then, no, you don’t need to load any DLLs. Base functionality from .NET (to somewhere between version 2 and 3) is included natively, you just need to whack the appropriate “using …;” statement at the start of your code file.
someone told me the same way.well I am wrong perhaps.thanks
