PasswordBox.SecurePassword在WinRT Store App上不可用

Question

我正在爲Windows 8.1，C＃和.NET Framework 4.5.1開發Windows應用商店應用程序。我想使用PasswordBox.SecurePassword但它似乎不可用。我已經將框架版本更改爲4.5，我已經嘗試使用.NET Framework 4.5.1進行WPF測試項目，但它不可用。

我試圖將PresentationFramework.dll程序集添加到我的Windows 8.1 Store應用程序，但是我不能。

我試圖做到這一點：

{ 
    PasswordBox pass = new PasswordBox(); 
    pass.SecurePassword // I'm checking if it is available 
} 

要檢查是否SecurePassword存在，但SecurePassword不適用於Windows應用商店的應用程序。

是否在Windows應用商店應用中提供SecurePassword？

Answer 1

恐怕說，Windows應用商店的應用程序無法使用SecureString的
您應該使用Windows.Security.Credentials的方法和對象

我想你希望的喜歡登錄工作，不要這樣做？
如果「Windows.Security.Credentials命名空間」是一個簡單的解決方案。

請看看上面的代碼

詞根記憶一個 「PasswordVault」 實例

-Registar數據
2a。使用PasswordVau lt.Add方法與PasswordCredential例如
PasswordCredential實例需要3個參數
第一個參數：資源名稱（任意值）類型的字符串
第二個參數：用戶名字符串類型
第3個參數：密碼字符串類型

- 證書數據
2b.Use PasswordVault.Retribe法2paraeters
第一個參數：資源名稱（必須使用您註冊使用相同的名字）
第2個參數：用戶名
返回PasswordCredential價值
你可以得到用戶名和密碼從PasswordCredential價值

例如

//data is a PasswordCredential value 

//get Username 
string username = data.UserName; 
//get Password 
string password = data.Password
