StorePermissionAttribute Class
Assembly: System (in system.dll)
'Declaration <SerializableAttribute> _ <AttributeUsageAttribute(AttributeTargets.Assembly Or AttributeTargets.Class Or AttributeTargets.Struct Or AttributeTargets.Constructor Or AttributeTargets.Method, AllowMultiple:=True, Inherited:=False)> _ Public NotInheritable Class StorePermissionAttribute Inherits CodeAccessSecurityAttribute 'Usage Dim instance As StorePermissionAttribute

The scope of the declaration that is allowed depends on the SecurityAction value that is used.
The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. The StorePermissionAttribute attribute is used only for declarative security. For imperative security, use the StorePermission class.
The following code example shows the use of the StorePermissionAttribute to deny the ability to add to a store. This code example is part of a larger example provided for the StorePermission class.
'Deny the permission the ability to add to a store. <StorePermission(SecurityAction.Deny, Flags:=StorePermissionFlags.AddToStore)> _ Private Shared Sub AddToStore(ByVal cert As X509Certificate2) Try Dim store As New X509Store("teststore", StoreLocation.CurrentUser) store.Open(OpenFlags.ReadWrite) ' The following attempt to add a certificate results in an exception being thrown. store.Add(cert) Return Catch e As SecurityException Console.WriteLine("Security exception thrown when attempting: " + _ CType(e.FirstPermissionThatFailed, System.Security.Permissions.StorePermission).Flags) Return End Try End Sub 'AddToStore
//Deny the permission the ability to add to a store.
/** @attribute StorePermission(SecurityAction.Deny, Flags =
StorePermissionFlags.AddToStore)
*/
private static void AddToStore(X509Certificate2 cert)
{
try
{
X509Store store = new X509Store("teststore",
StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadWrite);
// The following attempt to add a certificate results in
// an exception being thrown.
store.Add(cert);
return;
}
catch (System.Security.SecurityException e)
{
Console.WriteLine("Security exception thrown when attempting: "
+ ((StorePermission)e.get_FirstPermissionThatFailed()).get_Flags());
