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

注解

本地文件是包含在本地计算机上的文件。 无法通过网络驱动器访问的任何文件都是本地文件。

可以使用按位 AND 运算检查单个 FileIOPermissionAccess 值。
