这是我如何处理将照片发布到 Facebook 用户的墙上。 ImagePath 和 ImageName 是我传递给包含此代码的函数的字符串参数。

    var fbApp = new FacebookApp();
    var auth = new CanvasAuthorizer(fbApp);

    if (auth.IsAuthorized())
    {

        //Create a new dictionary of objects, with string keys
        Dictionary<string, object> parameters = new Dictionary<string, object>();

        string strDescription = txtDescription.Text;

        //Add elements to the dictionary
        if (string.IsNullOrEmpty(ImagePath) == false)
        {
            //There is an Image to add to the parameters                
            FacebookMediaObject media = new FacebookMediaObject
            {
                FileName = ImageName,
                ContentType = "image/jpeg"
            };

            byte[] img = File.ReadAllBytes(ImagePath);
            media.SetValue(img);

            parameters.Add("source", media);
            parameters.Add("message", strDescription);

            try
            {
                dynamic result = fbApp.Api("/me/photos", parameters, HttpMethod.Post);

            }
            catch (Exception ex)
            {
                //handle error....
                string strErr = ex.Message.ToString();
                lblValidationMsg.Text = strErr;
            }
        }            

    }
