Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

'Declaration
<SerializableAttribute> _
Public NotInheritable Class EventLogPermission _
	Inherits ResourcePermissionBase

The EventLogPermission type exposes the following members.

  NameDescription
Public methodEventLogPermissionInitializes a new instance of the EventLogPermission class.
Public methodEventLogPermission(EventLogPermissionEntry())Initializes a new instance of the EventLogPermission class with the specified permission entries.
Public methodEventLogPermission(PermissionState)Initializes a new instance of the EventLogPermission class with the specified permission state.
Public methodEventLogPermission(EventLogPermissionAccess, String)Initializes a new instance of the EventLogPermission class with the specified access levels and the name of the computer to use.

  NameDescription
Public propertyPermissionEntriesGets the collection of permission entries for this permissions request.

  NameDescription
Public methodAssertDeclares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues. (Inherited from CodeAccessPermission.)
Public methodCopyCreates and returns an identical copy of the current permission object. (Inherited from ResourcePermissionBase.)
Public methodDemandForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodDeny Obsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodEqualsDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Public methodFromXmlReconstructs a security object with a specified state from an XML encoding. (Inherited from ResourcePermissionBase.)
Public methodGetHashCodeGets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIntersectCreates and returns a permission object that is the intersection of the current permission object and a target permission object. (Inherited from ResourcePermissionBase.)
Public methodIsSubsetOfDetermines whether the current permission object is a subset of the specified permission. (Inherited from ResourcePermissionBase.)
Public methodIsUnrestrictedGets a value indicating whether the permission is unrestricted. (Inherited from ResourcePermissionBase.)
Public methodPermitOnlyPrevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodToStringCreates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public methodToXmlCreates and returns an XML encoding of the security object and its current state. (Inherited from ResourcePermissionBase.)
Public methodUnionCreates a permission object that combines the current permission object and the target permission object. (Inherited from ResourcePermissionBase.)

Do not grant EventLogPermission to partially trusted code. The ability to read and write the event log enables code to perform actions such as issuing event log messages in the name of another application.

NoteNote

If the event source that is specified by the EventLog.Source property for the event log does not exist, a new event source is created. To create an event source in Windows Vista and later versions of Windows, or Windows Server 2003, you must have administrative privileges.

The reason for this requirement is that all event logs, including security, must be searched to determine whether the event source is unique. Starting with Windows Vista, users do not have permission to access the security log; therefore, a SecurityException is thrown.

Starting with Windows Vista, User Account Control (UAC) determines the privileges of a user. If you are a member of the Built-in Administrators group, you are assigned two run-time access tokens: a standard user access token and an administrator access token. By default, you are in the standard user role. To execute the code that accesses the security log, you must first elevate your privileges from standard user to administrator. You can do this when you start an application by right-clicking the application icon and indicating that you want to run as an administrator.
