public sealed class SmtpPermissionAttribute : CodeAccessSecurityAttribute


Initializes a new instance of the SmtpPermissionAttribute class.


Gets or sets the level of access to SMTP servers controlled by the attribute.


Gets or sets a security action.(Inherited from SecurityAttribute.)


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared.(Inherited from SecurityAttribute.)


Creates a permission object that can be stored with the SecurityAction in an assembly's metadata.(Overrides SecurityAttribute.CreatePermission().)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The SmtpPermission and SmtpPermissionAttribute classes control access to SMTP host computers. The SmtpClient class demands an SmtpPermission when sending electronic mail to the SMTP host for delivery.

The SmtpAccess enumeration specifies the level of access controlled by an instance of this permission.
