C# PasswordBox.SecurePassword在WinRT应用商店应用程序上不可用

我正在为Windows 8.1、C和.NET Framework 4.5.1开发一个Windows应用商店应用程序

我正在尝试使用，但它似乎不可用。我已将框架版本更改为4.5，我已尝试使用.NETFramework 4.5.1的WPF测试项目，但它不可用

我已尝试将PresentationFramework.dll程序集添加到我的Windows 8.1应用商店应用程序中，但无法

我正在尝试这样做：

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

检查SecurePassword是否存在，但SecurePassword在Windows应用商店应用程序上不可用

Windows应用商店应用程序上是否有SecurePassword？

我担心Windows应用商店应用程序无法使用SecureString 您应该使用Windows.Security.Credentials的方法和对象

2007年10月夜间日本时间改写 我想你希望做像登录一样的工作，不是吗？ 在这种情况下，Windows.Security.Credentials命名空间是一个简单的解决方案

请看上面的代码

谢谢你的回答，但我不明白。是否有一个名为Windows.Security.Credentials的XAML控件？再次感谢您的回答，但我不是英国人或美国人，我不明白这句话中登录的含义：我想您希望像登录一样工作，不是吗？谢谢。而且我不是以英语为母语的人。我是日本人。在日本，认证任务通常称为登录任务。很抱歉让你产生误解

//data is a PasswordCredential value

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