任何人都可以建议我如何通过 WCF Web 服务从 iphone 应用程序中检索图像并将其保存到目录中。

我正在以 NSDATA 的形式从 iphone 应用程序接收图像（不知道，实际上 iphone 开发者正在给我一个图像作为 Nsdata）。我这样做是为了将此数据转换为图像并保存到我的目录

public Image byteArrayToImage(byte[] byteArrayIn)
{
Image returnImage = null;


string ApplicationVerifyPath = ConfigurationManager.AppSettings["ImagePath"].ToString();
ApplicationVerifyPath = ApplicationVerifyPath + "RetailerAdmin/ProductImages/";

using (MemoryStream ms = new MemoryStream(byteArrayIn, 0, byteArrayIn.Length))
{
ms.Write(byteArrayIn, 0, byteArrayIn.Length);
ms.Seek(0, SeekOrigin.Begin);
returnImage = Image.FromStream(ms);
returnImage.Save(ApplicationVerifyPath + returnImage, System.Drawing.Imaging.ImageFormat.Png);
}
return returnImage;
}

它正在显示（Image.FromStream（ms）中的参数无效错误。

请帮助我摆脱这个解决方案。

您可以尝试以下方式，就像我在 iPhone 中集成 WCF REST 服务时在我的一个项目中实现的那样。

获取 NSDATA 到字符串属性或变量。将此字符串用作 Base64 字符串并将其转换为图像并将其保存到您的目录。

public void Base64ToImage(string imageString)
{

   // Convert Base64 String to byte[]
   byte[] imageBytes = Convert.FromBase64String(imageString);
   MemoryStream ms = new MemoryStream(imageBytes, 0,
   imageBytes.Length);

   // Convert byte[] to Image
   ms.Write(imageBytes, 0, imageBytes.Length);
   System.Drawing.Image image = System.Drawing.Image.FromStream(ms, true);
   image.Save("Base64ToImage.png"); //Specify your filename here
}
