StrongNameMembershipCondition Constructor

Initializes a new instance of the StrongNameMembershipCondition class with the strong name public key blob, name, and version number that determine membership.

Namespace:  System.Security.Policy
Assembly:  mscorlib (in mscorlib.dll)

Public Sub New ( _
	blob As StrongNamePublicKeyBlob, _
	name As String, _
	version As Version _


Type: System.Security.Permissions.StrongNamePublicKeyBlob

The strong name public key blob of the software publisher.

Type: System.String

The simple name section of the strong name.

Type: System.Version

The version number of the strong name.


The blob parameter is Nothing.


The name parameter is Nothing.


The name parameter is an empty string ("").

Strong names are well suited to specifying code assemblies to which you give a rich set of powerful permissions. Since strong names are cryptographically verified, attackers cannot impersonate rightful assemblies and use their permissions.

The name and version parameters are optional. For example, you can create a StrongNameMembershipCondition that checks for PublicKey and Name (but not Version) by passing Nothing into the version parameter. If name is an empty string (""), an ArgumentException is thrown.
