ICredentials を実装するクラス
| クラス | 説明 |
|---|---|
| CredentialCache | 複数の資格情報にストレージを提供します。 |
| NetworkCredential | 基本認証、ダイジェスト認証、NTLM 認証、Kerberos 認証などのパスワードに基づく認証方式に資格情報を提供します。 |
解説
ICredentials インターフェイスには、アプリケーションにネットワーク資格情報を提供するオブジェクト用の GetCredential メソッドが用意されています。
使用例
[Visual Basic, C#, C++] ICredentials インターフェイスを使用する方法を次の例に示します。
Class CredentialInfo
Public uriObj As Uri
Public authenticationType As [String]
Public networkCredentialObj As NetworkCredential
Public Sub New(uriObj As Uri, authenticationType As [String], networkCredentialObj As NetworkCredential)
Me.uriObj = uriObj
Me.authenticationType = authenticationType
Me.networkCredentialObj = networkCredentialObj
End Sub 'New
End Class 'CredentialInfo
Private arrayListObj As ArrayList
Public Sub New()
arrayListObj = New ArrayList()
End Sub 'New
Public Sub Add(uriObj As Uri, authenticationType As [String], credential As NetworkCredential)
' adds a 'CredentialInfo' object into a list
arrayListObj.Add(New CredentialInfo(uriObj, authenticationType, credential))
End Sub 'Add
' Remove the 'CredentialInfo' object from the list which matches to the given 'Uri' and 'AuthenticationType'
Public Sub Remove(uriObj As Uri, authenticationType As [String])
Dim index As Integer
For index = 0 To arrayListObj.Count - 1
Dim credentialInfo As CredentialInfo = CType(arrayListObj(index), CredentialInfo)
If uriObj.Equals(credentialInfo.uriObj) And authenticationType.Equals(credentialInfo.authenticationType) Then
arrayListObj.RemoveAt(index)
End If
Next index
End Sub 'Remove
Public Function GetCredential(uriObj As Uri, authenticationType As [String]) As NetworkCredential Implements ICredentials.GetCredential
Dim index As Integer
For index = 0 To arrayListObj.Count - 1
Dim credentialInfoObj As CredentialInfo = CType(arrayListObj(index), CredentialInfo)
If uriObj.Equals(credentialInfoObj.uriObj) And authenticationType.Equals(credentialInfoObj.authenticationType) Then
Return credentialInfoObj.networkCredentialObj
End If
Next index
Return Nothing
