System.IO.File 不包含 ReadAllBytes C# [英] System.IO.File does not contain ReadAllBytes C#

问题描述

在 C# 中，我正在为 WP7 创建简单的 Facebook 应用程序，但遇到了一个问题.

In C# I am creating simple facebook application for WP7 and I came across a problem.

我正在尝试让您可以在相册或提要中上传图片.

I'm trying to do the part where you can upload a picture in the album or feed.

代码:

FacebookMediaObject facebookUploader = new FacebookMediaObject { FileName = "SplashScreenImage.jpg", ContentType = "image/jpg" };

var bytes = System.IO.File.ReadAllBytes(Server.MapPath("~") + facebookUploader.FileName);
facebookUploader.SetValue(bytes);

错误:

• System.IO.File 不包含 ReadAllBytes 的定义

推荐答案

我找到了解决方案.

代码:

string imageName = boxPostImage.Text;
StreamResourceInfo sri = null;
Uri jpegUri = new Uri(imageName, UriKind.Relative);
sri = Application.GetResourceStream(jpegUri);

try
{
    byte[] imageData = new byte[sri.Stream.Length];
    sri.Stream.Read(imageData, 0, System.Convert.ToInt32(sri.Stream.Length));

    FacebookMediaObject fbUpload = new FacebookMediaObject
    {
         FileName = imageName,
         ContentType = "image/jpg"
    };
    fbUpload.SetValue(imageData);


    IDictionary<string, object> parameters = new Dictionary<string, object>();
    parameters.Add("access_token", _AccessToken);
    parameters.Add("source", fbUpload);

    //_fbClient.PostAsync("/"+MainPage._albumId+"/photos", parameters);
    _fbClient.PostAsync("/me/photos", parameters);


    MessageBox.Show("Image has been posted successfully..");
}
catch (Exception error)
{
    MessageBox.Show("Sorry, there's an error occured, please try again.");
}
