Ejemplos

El ejemplo siguiente muestra el uso de los miembros de WindowsIdentity clase.The following example shows the use of members of WindowsIdentity class. Para obtener un ejemplo que muestra cómo obtener un Windows cuenta token mediante una llamada a Win32 no administrada LogonUser función y utilizar ese token para suplantar a otro usuario, consulte el WindowsImpersonationContext clase.For an example showing how to obtain a Windows account token through a call to the unmanaged Win32 LogonUser function, and use that token to impersonate another user, see the WindowsImpersonationContext class.
