ByVal uriPrefix As Uri, _ ByVal authType As String _)
[C#]
public void Remove(UriuriPrefix,stringauthType);
[C++]
public: void Remove(Uri* uriPrefix,String* authType);
[JScript]
public function Remove(
uriPrefix : Uri,authType : String);

解説
Remove メソッドは、指定した NetworkCredential インスタンスを CredentialCache から削除します。同じ NetworkCredential に対して Remove メソッドを何度も呼び出しても、効果はありません。
使用例
[Visual Basic, C#, C++] Remove メソッドを使用して、キャッシュから NetworkCredential インスタンスを削除する例を次に示します。
' Create a webrequest with the specified url .
Dim myWebRequest As WebRequest = WebRequest.Create(url)
myWebRequest.Credentials = myCredentialCache
Console.WriteLine(ControlChars.Cr + "Linked CredentialCache to your request.")
' Send the request and wait for response.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
'Process the response here
Console.Write("Response received successfully.")
'Call 'Remove' method to dispose credentials for current Uri as they would not be;
'required in any of the future requests.
myCredentialCache.Remove(myWebRequest.RequestUri, "Basic")
Console.WriteLine(ControlChars.Cr + "Your credentials have now been removed from the program's CredentialCache")
myWebResponse.Close()
[C#]
// Create a webrequest with the specified url.
WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Credentials = myCredentialCache;
Console.WriteLine("\nLinked CredentialCache to your request.");
// Send the request and wait for response.
WebResponse myWebResponse = myWebRequest.GetResponse();
// Process response here.
Console.Write("Response received successfully.");
// Call 'Remove' method to dispose credentials for current Uri as not required further.
myCredentialCache.Remove(myWebRequest.RequestUri,"Basic");
Console.WriteLine("\nYour credentials have now been removed from the program's CredentialCache");
myWebResponse.Close();
[C++]
// Create a webrequest with the specified url.
WebRequest* myWebRequest = WebRequest::Create(url);
myWebRequest->Credentials = myCredentialCache;
Console::WriteLine(S"\nLinked CredentialCache to your request.");
// Send the request and wait for response.
WebResponse* myWebResponse = myWebRequest->GetResponse();
// Process response here.
Console::Write(S"Response received successfully.");
// Call 'Remove' method to dispose credentials for current Uri as not required further.
myCredentialCache->Remove(myWebRequest->RequestUri, S"Basic");
Console::WriteLine(S"\nYour credentials have now been removed from the program's CredentialCache");
myWebResponse->Close();
