CodeConnectAccess.CreateOriginSchemeAccess メソッド

メモ : このメソッドは、.NET Framework version 2.0 で新しく追加されたものです。

コードの元のスキームを使用して指定されたポートへのアクセスを表す CodeConnectAccess インスタンスを返します。

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

Visual Basic (宣言)

Public Shared Function CreateOriginSchemeAccess
 ( _
    allowPort As Integer _
) As CodeConnectAccess

Visual Basic (使用法)

Dim allowPort As Integer
Dim returnValue As CodeConnectAccess

returnValue = CodeConnectAccess.CreateOriginSchemeAccess(allowPort)

public static CodeConnectAccess CreateOriginSchemeAccess
 (
    int allowPort
)

C++

public:
static CodeConnectAccess^ CreateOriginSchemeAccess (
    int allowPort
)

public static CodeConnectAccess CreateOriginSchemeAccess
 (
    int allowPort
)

JScript

public static function CreateOriginSchemeAccess
 (
    allowPort : int
) : CodeConnectAccess

パラメータ

allowPort: 返されたインスタンスによって表されるポート。

戻り値
指定したポートの CodeConnectAccess インスタンス。

例外

例外の種類	条件
ArgumentOutOfRangeException	allowPort が 0 未満です。または allowPort が 65,535 より大きい値です。

例外の種類

条件

ArgumentOutOfRangeException

allowPort が 0 未満です。

または

allowPort が 65,535 より大きい値です。

解説

このメソッドによって返される CodeConnectAccess インスタンスは、スキーム値 OriginScheme を保持します。元のスキームは、コードのダウンロード元 URI からのスキーム値です。

使用例

CodeConnectAccess オブジェクトを使用し、コードグループを作成してそのコードグループをポリシーレベルに追加するコード例を次に示します。

public static void SetNetCodeGroupAccess()
{
    const string userPolicyLevel = "User";
    // Locate the User policy level.
    PolicyLevel level = null;
    System.Collections.IEnumerator ph = 
        System.Security.SecurityManager.PolicyHierarchy();
    while(ph.MoveNext())
    {
        level = (PolicyLevel)ph.Current;
        if( level.Label == userPolicyLevel )
        {
            break;
        }
    }
    if (level.Label != userPolicyLevel)
        throw new ApplicationException("Could not find User
 policy level.");

    IMembershipCondition membership =
        new UrlMembershipCondition(@"http://www.contoso.com/*");
    NetCodeGroup codeGroup = new NetCodeGroup(membership);
    // Delete default settings.
    codeGroup.ResetConnectAccess();
    // Create an object that represents access to the FTP scheme and
 default port.
    CodeConnectAccess a1 = new CodeConnectAccess(Uri.UriSchemeFtp,
 CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the HTTPS scheme and
 default port.
    CodeConnectAccess a2 = new CodeConnectAccess(Uri.UriSchemeHttps
,
 CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the origin scheme
 and port.
    CodeConnectAccess a3 = CodeConnectAccess.CreateOriginSchemeAccess(CodeConnectAccess.OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a1);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a2);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a3);
    // Provide name and description information for caspol.exe tool.
    codeGroup.Name = "ContosoHttpCodeGroup";
    codeGroup.Description = "Code originating from contoso.com can connect back
 using the FTP or HTTPS.";
    // Add the code group to the User policy's root node.
    level.RootCodeGroup.AddChild(codeGroup);
    // Save the changes to the policy level.
    System.Security.SecurityManager.SavePolicy();
}
