在Windows Phone上將ByteArray轉換爲base64

我正在面對使用base64轉換器的巨大問題。我在Windows Phone上調用標準的base64轉換函數，但結果總是與Web轉換器以及Android和iOS平臺上的許多其他應用程序不同。在Windows Phone上將ByteArray轉換爲base64

基本上我從畫廊或相機拍攝圖像並將其轉換爲字節數組。字節數組傳遞給convert方法。

Convert.ToBase64String(bytearray);

結果字符串應該是這樣的：

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

但結果卻是被這個

它不同於沒有這麼多，但它是不同的。正確的是使用PHP生成的。 Windows手機是在圖像上使用UNICODE編碼生成的。

有誰知道在哪裏可能是一個問題？

使用WriteableBitmap嘗試使用這段代碼：

public string GetBase64Encoding(BitmapImage imageUrl) 
     { 
     byte[] bytearray = null; 
     using (MemoryStream ms = new MemoryStream()) 
      { 
      if (imageUrl == null) 
       { 

       } 
      else 
       { 
       WriteableBitmap wbitmp = new WriteableBitmap((BitmapImage)imageUrl); 

       wbitmp.SaveJpeg(ms, 46, 38, 0, 100); 

       bytearray = ms.ToArray(); 
       } 
      } 
     string str = Convert.ToBase64String(bytearray); 

     return str; 
     }

希望它能幫助！
