I have to Impersonate my windowsApplication (C#) to the Credential (which will be send by user).. Give below is my same function (Which wont work) what i need. public class clsImpersonate{ public void Impersonate(ICredential UserCredential){ WindowsIdentity newId = (WindowsIdentity)UserCredential; WindowsImpersonationContext impersonatedUser = newId.Impersonate(); MessageBox.Show(WindowsIdentity.GetCurrent().Name); } } I will call the function like below.. public static void mail(){ clsImpersonate objImp = new clsImpersonate(); ICredentials NWC = System.Net.CredentialCache.DefaultCredentials; objImp.Impersonate(NWC); } But above code is wrong because we can not typecast from Icredential to WinndowsIdentity. Is there any other way to do the same. Thanks Saravanakumar.K India
