FileIOPermission Constructor (FileIOPermissionAccess, String^)

.NET Framework (current version)

Initializes a new instance of the FileIOPermission class with the specified access to the designated file or directory.

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

Syntax

public:
FileIOPermission(
	FileIOPermissionAccess access,
	String^ path
)

Parameters

access: Type: System.Security.Permissions::FileIOPermissionAccess
A bitwise combination of the FileIOPermissionAccess enumeration values.

path: Type: System::String^
The absolute path of the file or directory.

Exceptions

Exception	Condition
ArgumentException	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.

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.

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.

C++

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);
}
