GenericPrincipal コンストラクタ

ユーザー ID と、その ID が表すユーザーが属しているロールの名前の配列から、GenericPrincipal クラスの新しいインスタンスを初期化します。

名前空間: System.Security.Principal
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Sub New ( _
    identity As IIdentity, _
    roles As String() _
)

Visual Basic (使用法)

Dim identity As IIdentity
Dim roles As String()

Dim instance As New GenericPrincipal(identity,
 roles)

public GenericPrincipal (
    IIdentity identity,
    string[] roles
)

C++

public:
GenericPrincipal (
    IIdentity^ identity, 
    array<String^>^ roles
)

public GenericPrincipal (
    IIdentity identity, 
    String[] roles
)

JScript

public function GenericPrincipal (
    identity : IIdentity, 
    roles : String[]
)

パラメータ

identity: 任意のユーザーを表す IIdentity の基本実装。

roles: identity パラメータによって表されるユーザーが属しているロールの名前の配列。

例外

例外の種類	条件
ArgumentNullException	identity パラメータが null 参照 (Visual Basic では Nothing) です。

使用例

GenericPrincipal コンストラクタを使用する方法を次のコードに示します。このコード例は、GenericPrincipal クラスのトピックで取り上げているコード例の一部分です。

Visual Basic

Dim roles(10) As String
Dim windowsIdentity As WindowsIdentity = windowsIdentity.GetCurrent()

If (windowsIdentity.IsAuthenticated) Then
    ' Add custom NetworkUser role.
    roles(0) = "NetworkUser"
End If

If (windowsIdentity.IsGuest) Then
    ' Add custom GuestUser role.
    roles(1) = "GuestUser"
End If


If (windowsIdentity.IsSystem) Then
    ' Add custom SystemUser role.
    roles(2) = "SystemUser"
End If

' Construct a GenericIdentity object based on the current Windows
' identity name and authentication type.
Dim authenticationType As String
 = windowsIdentity.AuthenticationType
Dim userName As String =
 windowsIdentity.Name
Dim genericIdentity = _
    New GenericIdentity(userName, authenticationType)

' Construct a GenericPrincipal object based on the generic identity
' and custom roles for the user.
Dim genericPrincipal As New
 GenericPrincipal(genericIdentity, roles)

WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
string[] roles = new string[10];
if (windowsIdentity.IsAuthenticated)
{
    // Add custom NetworkUser role.
    roles[0] = "NetworkUser";
}

if (windowsIdentity.IsGuest)
{
    // Add custom GuestUser role.
    roles[1] = "GuestUser";
}

if (windowsIdentity.IsSystem)
{
    // Add custom SystemUser role.
    roles[2] = "SystemUser";
}

// Construct a GenericIdentity object based on the current Windows
// identity name and authentication type.
string authenticationType = windowsIdentity.AuthenticationType;
string userName = windowsIdentity.Name;
GenericIdentity genericIdentity =
    new GenericIdentity(userName, authenticationType);

// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal genericPrincipal =
    new GenericPrincipal(genericIdentity, roles);

C++

WindowsIdentity^ windowsIdentity = WindowsIdentity::GetCurrent();
array<String^>^roles = gcnew array<String^>(10);
if ( windowsIdentity->IsAuthenticated )
{
   
   // Add custom NetworkUser role.
   roles[ 0 ] = L"NetworkUser";
}

if ( windowsIdentity->IsGuest )
{
   
   // Add custom GuestUser role.
   roles[ 1 ] = L"GuestUser";
}

if ( windowsIdentity->IsSystem )
{
   
   // Add custom SystemUser role.
   roles[ 2 ] = L"SystemUser";
}

// Construct a GenericIdentity object based on the current Windows
// identity name and authentication type.
String^ authenticationType = windowsIdentity->AuthenticationType;
String^ userName = windowsIdentity->Name;
GenericIdentity^ genericIdentity = gcnew GenericIdentity(
   userName,authenticationType );

// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal^ genericPrincipal = gcnew GenericPrincipal(
   genericIdentity,roles );

WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
String roles[] = new String[10];
if (windowsIdentity.get_IsAuthenticated()) {
    // Add custom NetworkUser role.
    roles.set_Item(0, "NetworkUser");
}

if (windowsIdentity.get_IsGuest()) {
    // Add custom GuestUser role.
    roles.set_Item(1, "GuestUser");
}

if (windowsIdentity.get_IsSystem()) {
    // Add custom SystemUser role.
    roles.set_Item(2, "SystemUser");
}
// Construct a GenericIdentity object based on the current Windows
// identity name and authentication type.
String authenticationType = windowsIdentity.get_AuthenticationType();
String userName = windowsIdentity.get_Name();
GenericIdentity genericIdentity = new GenericIdentity(userName,
 
    authenticationType);
// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal genericPrincipal = new GenericPrincipal(genericIdentity
,
    roles);
