向凭据缓存添加 NetworkCredential 实例。
重载
Add(Uri, String, NetworkCredential) |
向凭据缓存添加一个要与 SMTP 以外的协议一起使用的 NetworkCredential 实例,并将其与统一资源标识符 (URI) 前缀和身份验证协议关联。 |
Add(String, Int32, String, NetworkCredential) |
向凭据缓存添加要与 SMTP 一起使用的 NetworkCredential 实例,并将其与主机、端口和身份验证协议关联。 使用此方法添加的凭据仅对 SMTP 有效。 此方法对 HTTP 或 FTP 请求无效。 |

向凭据缓存添加一个要与 SMTP 以外的协议一起使用的 NetworkCredential 实例,并将其与统一资源标识符 (URI) 前缀和身份验证协议关联。
public:
void Add(Uri ^ uriPrefix, System::String ^ authType, System::Net::NetworkCredential ^ cred);
public void Add (Uri uriPrefix, string authType, System.Net.NetworkCredential cred);
member this.Add : Uri * string * System.Net.NetworkCredential -> unit
Public Sub Add (uriPrefix As Uri, authType As String, cred As NetworkCredential)
参数
- authType
- String
在 uriPrefix
中命名的资源所使用的身份验证方案。
- cred
- NetworkCredential
要添加到凭据缓存中的 NetworkCredential。
例外
相同的凭据被添加多次。
示例
下面的代码示例使用多个安全凭据初始化 , CredentialCache 并通过 使用这些凭据 WebRequest。
CredentialCache^ myCache = gcnew CredentialCache;
myCache->Add( gcnew Uri( "http://www.contoso.com/" ), "Basic", gcnew NetworkCredential( UserName,SecurelyStoredPassword ) );
myCache->Add( gcnew Uri( "http://www.contoso.com/" ), "Digest", gcnew NetworkCredential( UserName,SecurelyStoredPassword,Domain ) );
wReq->Credentials = myCache;
CredentialCache myCache = new CredentialCache();
myCache.Add(new Uri("http://www.contoso.com/"),"Basic",new NetworkCredential(UserName,SecurelyStoredPassword));
myCache.Add(new Uri("http://www.contoso.com/"),"Digest", new NetworkCredential(UserName,SecurelyStoredPassword,Domain));
wReq.Credentials = myCache;
Dim myCache As New CredentialCache()
myCache.Add(New Uri("http://www.contoso.com/"), "Basic", New NetworkCredential(UserName, SecurelyStoredPassword))
myCache.Add(New Uri("http://www.contoso.com/"), "Digest", New NetworkCredential(UserName, SecurelyStoredPassword, Domain))
wReq.Credentials = myCache
注解
方法 Add 将用于 SMTP 以外的协议的实例放入 NetworkCredential 中 CredentialCache。 缓存按凭据添加到它的顺序存储凭据。 GetCredential(Uri, String)调用 方法时,它将返回正确的匹配NetworkCredential实例。

port
小于零。
示例
下面的代码示例使用多个安全凭据初始化 CredentialCache ,以便与 SMTP 一起使用,并将其中一个 SmtpClient凭据用于 。
SmtpClient^ client = gcnew SmtpClient("ContosoMail", 45);
MailAddress^ from = gcnew MailAddress("sender@SenderMailServerName.com", "Sender Name");

{
myCredentialCache->Add("ContoscoMail", 35, "Basic", myCreds);
myCredentialCache->Add("ContoscoMail", 45, "NTLM", myCreds);
client->Credentials = myCredentialCache->GetCredential("ContosoMail", 45, "NTLM");
client->Send(message);
Console::WriteLine("Goodbye.");

注解
此方法将用于 SMTP 的实例放入 NetworkCredential 中 CredentialCache。 缓存按凭据添加到它的顺序存储凭据。
GetCredential(String, Int32, String)调用 方法时,它将返回通过NetworkCredential匹配 host
、 port
和 authType
选择的实例。 比较不区分大小写。
支持的值为 authType
“NTLM”、“Digest”、“Kerberos”和“Negotiate”。
使用此方法添加的凭据仅对 SMTP 有效。 此方法不适用于 HTTP 或 FTP 协议。
