c# - 用户名和密码数据 Windows Phone 8 应用程序

Question

我正在编写一个 Windows Phone 8 应用程序，该应用程序使用 API 提取应用程序需要的一些数据并使用该 API，需要用户名和密码。我已获得此用户名和密码，它似乎有效，但我想知道在应用程序中使用此用户名和密码的正确方法是什么？

我可以简单地添加如下内容吗:

string userName = "username";
string passWord = "password";

然后在需要时将它们传递到 WebRequest 中？还是我应该以某种特殊方式将此信息存储在应用程序中？

需要说明的是，用户不需要自己的用户名或密码，这个通用的应该可以。

您可以加密隔离存储中的数据。 Here是教程

以防链接失效，这里是用于写入和读取 secret PIN 的应用代码。

using System.IO;
using System.IO.IsolatedStorage;
using System.Text;
using System.Security.Cryptography;

private string FilePath = "pinfile";

private void BtnStore_Click(object sender, RoutedEventArgs e)
{
    // Convert the PIN to a byte[].
    byte[] PinByte = Encoding.UTF8.GetBytes(TBPin.Text);

    // Encrypt the PIN by using the Protect() method.
    byte[] ProtectedPinByte = ProtectedData.Protect(PinByte, null);

    // Store the encrypted PIN in isolated storage.
    this.WritePinToFile(ProtectedPinByte);

    TBPin.Text = "";
}

private void WritePinToFile(byte[] pinData)
{
    // Create a file in the application's isolated storage.
    IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication();
    IsolatedStorageFileStream writestream = new IsolatedStorageFileStream(FilePath, System.IO.FileMode.Create, System.IO.FileAccess.Write, file);

    // Write pinData to the file.
    Stream writer = new StreamWriter(writestream).BaseStream;
    writer.Write(pinData, 0, pinData.Length);
    writer.Close();
    writestream.Close();
}

private void BtnRetrieve_Click(object sender, RoutedEventArgs e)
{
    // Retrieve the PIN from isolated storage.
    byte[] ProtectedPinByte = this.ReadPinFromFile();

    // Decrypt the PIN by using the Unprotect method.
    byte[] PinByte = ProtectedData.Unprotect(ProtectedPinByte, null);

    // Convert the PIN from byte to string and display it in the text box.
    TBPin.Text = Encoding.UTF8.GetString(PinByte, 0, PinByte.Length);

}

private byte[] ReadPinFromFile()
{
    // Access the file in the application's isolated storage.
    IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication();
    IsolatedStorageFileStream readstream = new IsolatedStorageFileStream(FilePath, System.IO.FileMode.Open, FileAccess.Read, file);

    // Read the PIN from the file.
    Stream reader =  new StreamReader(readstream).BaseStream;
    byte[] pinArray = new byte[reader.Length];

    reader.Read(pinArray, 0, pinArray.Length);
    reader.Close();
    readstream.Close();

    return pinArray;
}
