实现

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 = 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

类 CredentialCache 存储多个 Internet 资源的凭据。 需要访问多个资源的应用程序可以将这些资源的凭据存储在实例 CredentialCache 中，然后根据需要向 Internet 资源提供正确的凭据集。 GetCredential调用 方法时，它会将统一资源标识符 (URI) 与缓存中存储的身份验证类型进行比较，并返回匹配的第一组凭据。

属性 DefaultCredentials 包含当前安全上下文的系统凭据。 对于客户端应用程序，这些表示当前登录用户的用户名、密码和域。 对于 ASP.NET 应用程序，默认凭据是登录用户或正在模拟的用户的用户凭据。
