Question

我正在尝试从sharepoint下载文件，我有这个代码并抛出错误代码500.

       static void DownloadFile(){
        string serverFilePath = "Here goes my URL, that open the file from any tab";
        var password = new SecureString();
        foreach (char c in Configuration.password) {
            password.AppendChar(c);
        }
        //  theese are the credentials and work fine because I tested in another method
        var o365credentials = new SharePointOnlineCredentials(Configuration.userName, password);

        var url = string.Format("{0}/{1}", Configuration.siteUrl, serverFilePath);
        //  My destination folder
        string destPath = @"C:\publisher";
        var request = System.Net.HttpWebRequest.Create(url);
        request.Credentials = o365credentials;
        using (var sReader = new StreamReader(request.GetResponse().GetResponseStream())) {
            using (var sWriter = new StreamWriter(destPath)) {
                sWriter.Write(sReader.ReadToEnd());
            }
        }
    }

您可以使用WebRequest来完成此任务，以便从sharepoint网站下载文件：

public void DownloadFile(string serverFilePath, string destPath)
{
    var url = string.Format("{0}/{1}", ServerURL, serverFilePath);
    Directory.CreateDirectory(Path.GetDirectoryName(destPath)); // this method creates your directory
    var request = System.Net.HttpWebRequest.Create(url);
    request.Credentials = System.Net.CredentialCache.DefaultCredentials;
    using (var sReader = new StreamReader(request.GetResponse().GetResponseStream()))
    {
        using (var sWriter = new StreamWriter(destPath))
        {
            sWriter.Write(sReader.ReadToEnd());
        }
    }
}
