Question

I do not understand the return type… I am a VB developer. is it returning some array???

[System.Web.Services.WebMethod]
[System.Web.Script.Services.ScriptMethod]
public static object GetUploadStatus()
{
    //Get the length of the file on disk and divide that by the length of the stream
    UploadDetail info = (UploadDetail)HttpContext.Current.Session["UploadDetail"];
    if (info != null && info.IsReady)
    {
        int soFar = info.UploadedLength;
        int total = info.ContentLength;
        int percentComplete = (int)Math.Ceiling((double)soFar / (double)total * 100);
        string message = "Uploading...";
        string fileName = string.Format("{0}", info.FileName);
        string downloadBytes = string.Format("{0} of {1} Bytes", soFar, total);
        return new {
                percentComplete = percentComplete,
                message = message,
                fileName = fileName,
                downloadBytes = downloadBytes};
    }
    //Not ready yet
    return null;
}

thank you

It is returning an anonymous type (VB.NET reference). It is a type that has no corresponding class.

Visual Basic supports anonymous types, which enable you to create objects without writing a class definition for the data type. Instead, the compiler generates a class for you. The class has no usable name, inherits directly from Object, and contains the properties you specify in declaring the object. Because the name of the data type is not specified, it is referred to as an anonymous type.
