周轉基金。 在服務端使用 Windows 憑據

Question

我有 WPF 和服務的客戶。 它適用於安全模式=無。 但是現在我需要在服務端調用服務以在 Azure 上執行某些操作的用戶的 Windows 憑據。 所以我更改了配置，現在是以下內容：

在服務方面，我嘗試使用

System.Net.CredentialCache.DefaultCredentials

或者

System.Net.CredentialCache.DefaultNetworkCredentials

但他們返回空對象.... 我該如何解決這個問題？

Answer 1

經過我的測試，我發現System.Net.CredentialCache.DefaultCredentials 不返回null，無論是在客戶端還是在服務器端。 您想通過 System.Net.CredentialCache.DefaultCredentials 獲取用戶名、密碼或域嗎？ 如果是這種情況，它將返回 null，因為 ICredentials 返回的實例 DefaultCredentials 不能用於查看當前安全上下文的用戶名、密碼或域。
