<summary>
<para> Used to declaratively specify security actions to control
access to files and directories.</para>
</summary>
<remarks>
<block subset="none" type="note">
<para> The level of access to a file or directory is specified using the members of the
current instance. For example, to specify read permissions for a file, set the
<see cref="P:System.Security.Permissions.FileIOPermissionAttribute.Read" /> property
equal to the name of the file.</para>
<para> 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 for
declarative security only. For imperative security, use the corresponding
permission class, <see cref="T:System.Security.Permissions.FileIOPermission" />.</para>
<para>The allowable <see cref="T:System.Security.Permissions.FileIOPermissionAttribute" /> targets are
determined by the <see cref="T:System.Security.Permissions.SecurityAction" /> passed to the constructor.</para>
</block>
<para>Case-sensitivity of file and directory names is
platform dependent. The set of characters that are valid for use in file and
directory names is determined by the current file system.</para>
</remarks>
<example>
<para>The following example shows a declarative request for full access to the
specified file. The <see cref="F:System.Security.Permissions.SecurityAction.RequestMinimum" /> security action
indicates that this is the minimum permission required for the target assembly
to be able to execute.</para>
<para>
<c>[assembly:FileIOPermissionAttribute(SecurityAction.RequestMinimum, All="\\example\\sample.txt")]
</c>
</para>
<para>The following example shows how to demand that the
calling code has unrestricted access to files and directories. Demands are
typically made to protect methods or classes from malicious code. </para>
<para>
<c>[FileIOPermissionAttribute(SecurityAction.Demand, Unrestricted=true)]</c>
