FileIOPermission(PermissionState)
- Source:
- FileIOPermission.cs
- Source:
- FileIOPermission.cs
Initializes a new instance of the FileIOPermission class with fully restricted or unrestricted permission as specified.
public:
FileIOPermission(System::Security::Permissions::PermissionState state);public FileIOPermission (System.Security.Permissions.PermissionState state);new System.Security.Permissions.FileIOPermission : System.Security.Permissions.PermissionState -> System.Security.Permissions.FileIOPermissionPublic Sub New (state As PermissionState)Parameters
- state
- PermissionState
One of the PermissionState enumeration values.
Exceptions
The state parameter is not a valid value of PermissionState.
Examples
The following code example creates a new instance of the FileIOPermission class with fully restricted read access.
FileIOPermission^ f = gcnew FileIOPermission( PermissionState::None );
f->AllLocalFiles = FileIOPermissionAccess::Read;
try
{
f->Demand();
}
catch (SecurityException^ s)
{
Console::WriteLine(s->Message);
}
FileIOPermission f = new FileIOPermission(PermissionState.None);
f.AllLocalFiles = FileIOPermissionAccess.Read;
try
{
f.Demand();
}
catch (SecurityException s)
{
Console.WriteLine(s.Message);
}
Dim f As New FileIOPermission(PermissionState.None)
f.AllLocalFiles = FileIOPermissionAccess.Read
Try
f.Demand()
Catch s As SecurityException
Console.WriteLine(s.Message)
End Try
Remarks
Creates either fully restricted (None) or Unrestricted access to files and directories.
Applies to
FileIOPermission(FileIOPermissionAccess, String)
- Source:
- FileIOPermission.cs
- Source:
- FileIOPermission.cs
Initializes a new instance of the FileIOPermission class with the specified access to the designated file or directory.
public:
FileIOPermission(System::Security::Permissions::FileIOPermissionAccess access, System::String ^ path);public FileIOPermission (System.Security.Permissions.FileIOPermissionAccess access, string path);new System.Security.Permissions.FileIOPermission : System.Security.Permissions.FileIOPermissionAccess * string -> System.Security.Permissions.FileIOPermissionPublic Sub New (access As FileIOPermissionAccess, path As String)Parameters
- access
- FileIOPermissionAccess
A bitwise combination of the FileIOPermissionAccess enumeration values.
- path
- String
The absolute path of the file or directory.
Exceptions
The access parameter is not a valid value of FileIOPermissionAccess.
-or-
The path parameter is not a valid string.
-or-
The path parameter does not specify the absolute path to the file or directory.
Examples
The following code example shows the use of the FileIOPermission.FileIOPermission(FileIOPermissionAccess, String) constructor to create a new instance of the FileIOPermission class, which provides complete access to the C:\test_r file.
FileIOPermission^ f2 = gcnew FileIOPermission( FileIOPermissionAccess::Read,"C:\\test_r" );
f2->AddPathList( (FileIOPermissionAccess) (FileIOPermissionAccess::Write | FileIOPermissionAccess::Read), "C:\\example\\out.txt" );
try
{
f2->Demand();
}
catch (SecurityException^ s)
{
Console::WriteLine(s->Message);
}
FileIOPermission f2 = new FileIOPermission(FileIOPermissionAccess.Read, "C:\\test_r");
f2.AddPathList(FileIOPermissionAccess.Write | FileIOPermissionAccess.Read, "C:\\example\\out.txt");
try
{
f2.Demand();
}
catch (SecurityException s)
{
Console.WriteLine(s.Message);
}
Dim f2 As New FileIOPermission(FileIOPermissionAccess.Read, "C:\test_r")
f2.AddPathList(FileIOPermissionAccess.Write Or FileIOPermissionAccess.Read, "C:\example\out.txt")
Try
f2.Demand()
Catch s As SecurityException
Console.WriteLine(s.Message)
End Try
Remarks
This constructor allows only one of the FileIOPermissionAccess values to be specified for the specified file or directory. Use the AddPathList method to define complex permissions.
Applies to
FileIOPermission(FileIOPermissionAccess, String[])
- Source:
- FileIOPermission.cs
- Source:
- FileIOPermission.cs
Initializes a new instance of the FileIOPermission class with the specified access to the designated files and directories.
public:
FileIOPermission(System::Security::Permissions::FileIOPermissionAccess access, cli::array <System::String ^> ^ pathList);public FileIOPermission (System.Security.Permissions.FileIOPermissionAccess access, string[] pathList);new System.Security.Permissions.FileIOPermission : System.Security.Permissions.FileIOPermissionAccess * string[] -> System.Security.Permissions.FileIOPermissionPublic Sub New (access As FileIOPermissionAccess, pathList As String())Parameters
- access
- FileIOPermissionAccess
A bitwise combination of the FileIOPermissionAccess enumeration values.
- pathList
- String[]
An array containing the absolute paths of the files and directories.
Exceptions
The access parameter is not a valid value of FileIOPermissionAccess.
-or-
An entry in the pathList array is not a valid string.
Remarks
This constructor allows only one FileIOPermissionAccess value to be specified for the specified files and directories. Use the AddPathList method to define complex permissions.
Applies to
FileIOPermission(FileIOPermissionAccess, AccessControlActions, String)
- Source:
- FileIOPermission.cs
- Source:
- FileIOPermission.cs
Initializes a new instance of the FileIOPermission class with the specified access to the designated file or directory and the specified access rights to file control information.
public:
FileIOPermission(System::Security::Permissions::FileIOPermissionAccess access, System::Security::AccessControl::AccessControlActions actions, System::String ^ path);public:
FileIOPermission(System::Security::Permissions::FileIOPermissionAccess access, System::Security::AccessControl::AccessControlActions control, System::String ^ path);public FileIOPermission (System.Security.Permissions.FileIOPermissionAccess access, System.Security.AccessControl.AccessControlActions actions, string path);public FileIOPermission (System.Security.Permissions.FileIOPermissionAccess access, System.Security.AccessControl.AccessControlActions control, string path);new System.Security.Permissions.FileIOPermission : System.Security.Permissions.FileIOPermissionAccess * System.Security.AccessControl.AccessControlActions * string -> System.Security.Permissions.FileIOPermissionnew System.Security.Permissions.FileIOPermission : System.Security.Permissions.FileIOPermissionAccess * System.Security.AccessControl.AccessControlActions * string -> System.Security.Permissions.FileIOPermissionPublic Sub New (access As FileIOPermissionAccess, actions As AccessControlActions, path As String)Public Sub New (access As FileIOPermissionAccess, control As AccessControlActions, path As String)Parameters
- access
- FileIOPermissionAccess
A bitwise combination of the FileIOPermissionAccess enumeration values.
- actionscontrol
- AccessControlActions
A bitwise combination of the AccessControlActions enumeration values.

Exceptions
The access parameter is not a valid value of FileIOPermissionAccess.
-or-

Remarks
This constructor allows only one FileIOPermissionAccess value to be specified for the specified file or directories. Use the AddPathList method to define complex permissions.
The control parameter specifies whether the access control list (ACL) for the file or directory specified by path can be changed, viewed, or cannot be accessed.
Important
An access control list (ACL) describes individuals or groups who have, or do not have, rights to specific actions on the given file and its properties. The ability to change or view an ACL is an important permission and should be granted with caution.
