Example 3. The handle of a Windows account token. This token is usually retrieved through a call to unmanaged code, such as a call to the Windows API LogonUser function. An object that represents the Windows user prior to impersonation; this object can be used to revert to the original user's context. If another user is currently being impersonated, control reverts to the original user. After using Impersonate IntPtr , it is important to call the Undo method to end the impersonation.

Impersonation The APIs for impersonation are provided in. Principal namespace: Newer code. Unicode ] internal static extern bool LogonUser String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, out IntPtr phToken ; This is the basic call definition, however there is a lot more to consider to actually using it in production: Obtaining a handle with the "safe" access pattern.
Closing the native handles appropriately Code access security CAS trust levels in. A Combined and Easier Approach Instead of writing all of this yourself, consider using my SimpleImpersonation library, which combines impersonation and user access into a single API.

Straightforward and easy to incorporate into my solution. Thanks much for doing all the hard work! Thanks for posting this. However, in the using statement I tried this line of code System. Name and the result was just the username I logged in with not the one I passed into the Impersonation contructor.
Chris - You would need to use one of the other login types. Type 9 only provides impersonation on outbound network credentials.
One would assume types 4 and 5 do also, for service or batch applications. See the link I referenced in the post. Sophit - It already does. Sophit - The reference source code here clearly shows Undo being called during disposal. Show 17 more comments. Here is some good overview of. NET impersonation concepts. Impersonate Method check out the code samples Basically you will be leveraging these classes that are out of the box in the. NET framework: WindowsImpersonationContext WindowsIdentity The code can often get lengthy though and that is why you see many examples like the one you reference that try to simplify the process.
Eric Schoonover Eric Schoonover Just a note that impersonation is not the silver bullet and some APIs are simply not designed to work with impersonation. That link from the Dutch programmer's blog was excellent.
Much more intuitive approach to impersonation than the other techniques presented. This is probably what you want: using System. Principal; using WindowsIdentity. Esteban Araya Esteban Araya This code looks like it can impersonate only the Current windows Identity. Is there a way to get the WindowsIdentity object of another user? The link in your edit msdn. This type is also for higher performance servers that process many plaintext ''' authentication attempts at a time, such as mail or Web servers.
The account provided must have the service privilege enabled. A server can accept plaintext credentials ''' from a client, call LogonUser, verify that the user can access the system across the network, and still ''' communicate with other servers.
Format "Could not impersonate the elevated user. Dispose Me.
