StorePermissionAttribute Class

Allows security actions for StorePermission to be applied to code using declarative security. This class cannot be inherited.

Namespace: System.Security.Permissions
Assembly: System (in system.dll)

[SerializableAttribute] 
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false)] 
public sealed class StorePermissionAttribute : CodeAccessSecurityAttribute
/** @attribute SerializableAttribute() */ 
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) */ 
public final class StorePermissionAttribute extends CodeAccessSecurityAttribute
SerializableAttribute 
AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) 
public final class StorePermissionAttribute extends CodeAccessSecurityAttribute
Not applicable.

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 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 (SecurityException e)
    {
        Console.WriteLine("Security exception thrown when attempting: " + 
            ((StorePermission)e.FirstPermissionThatFailed).Flags);
        return;
    }
}

//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());
        return;
    }
} //AddToStore
