How to get current user privileges in MS Dynamics CRM on server side

Question

I\'m working on MS CRM plugin, and it should be able to determine whether the current user has write access to the current entity. I don\'t know how to approach this task.

Answer 1

Here is what I have come up with — this code will check, does current user has given privilege on current record:

// Requesting user's access rights to current record
var principalAccessRequest = new RetrievePrincipalAccessRequest
{
    Principal = new EntityReference("systemuser", localContext.PluginExecutionContext.UserId),
    Target = new EntityReference(localContext.PluginExecutionContext.PrimaryEntityName, localContext.PluginExecutionContext.PrimaryEntityId)
};

// Response will contain AccessRights mask, like AccessRights.WriteAccess | AccessRights.ReadAccess | ...
var principalAccessResponse = (RetrievePrincipalAccessResponse)localContext.OrganizationService.Execute(principalAccessRequest);

if ((principalAccessResponse.AccessRights & AccessRights.WriteAccess) != AccessRights.None)
{
    ...
    ...
    ...
}

The code inside if statement will be executed if user has WriteAccess to current record.
