FileDialogPermissionAttribute Class

Definition

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

public ref class FileDialogPermissionAttribute sealed : System::Security::Permissions::CodeAccessSecurityAttribute
[System.Runtime.InteropServices.ComVisible(true)]
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true, Inherited=false)]
[System.Serializable]
public sealed class FileDialogPermissionAttribute : System.Security.Permissions.CodeAccessSecurityAttribute
type FileDialogPermissionAttribute = class
    inherit CodeAccessSecurityAttribute
Public NotInheritable Class FileDialogPermissionAttribute
Inherits CodeAccessSecurityAttribute

Attributes

Examples

The following code example demonstrates how to demand that the calling code have FileDialogPermission. Demands are typically made in managed libraries (DLLs) to help protect methods or classes from potentially harmful code.

[FileDialogPermissionAttribute(SecurityAction::Demand,Unrestricted=true)]
[FileDialogPermissionAttribute(SecurityAction.Demand, Unrestricted=true)]
<FileDialogPermissionAttribute(SecurityAction.Demand, _
 Unrestricted := True)> Public Class SampleClass

Remarks

Important

Partially trusted code is no longer supported. This attribute has no effect in .NET Core.

The scope of the declaration that is allowed depends on the SecurityAction 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. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.

Constructors

FileDialogPermissionAttribute(SecurityAction)

Initializes a new instance of the FileDialogPermissionAttribute class with the specified SecurityAction.

Properties

Action

Gets or sets a security action.

(Inherited from SecurityAttribute)
Open

Gets or sets a value indicating whether permission to open files through the file dialog is declared.

Save

Gets or sets a value indicating whether permission to save files through the file dialog is declared.

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)
Unrestricted

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

(Inherited from SecurityAttribute)

Methods

CreatePermission()

Creates and returns a new FileDialogPermission.

Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)
GetHashCode()

Returns the hash code for this instance.

(Inherited from Attribute)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(Inherited from Attribute)
Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

Explicit Interface Implementations

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

Maps a set of names to a corresponding set of dispatch identifiers.

(Inherited from Attribute)
_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)
_Attribute.GetTypeInfoCount(UInt32)

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

(Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)
