【问题标题】：I am trying to access sharepoint via C# code and i am getting UNAUTHORIZED access error but I can log web sharepoint without any issues我正在尝试通过 C# 代码访问共享点，但我收到未经授权的访问错误，但我可以毫无问题地记录网络共享点

【问题描述】：

我正在开发 C#.net 应用程序，该应用程序将使用客户端对象模型方法与 Sharepoint 2013 交互以下载和上传文件。当我使用我的凭据运行 C#.net 应用程序时，它给了我以下错误。

$exception {"远程服务器返回错误：(401) Unauthorized."} System.Net.WebException

但是，如果我使用相同的凭据通过 Web Sharepoint 登录，它就可以正常工作。我不明白我需要在我的代码中插入什么才能访问 SharePoint 以下载/上传文件。

任何建议都会有所帮助。提前致谢！

   public void test()
    {
        Console.WriteLine("SharePoint Online site URL:");

        try
        {
            using (var context = new ClientContext(webSPOUrl))
            {
                Web web = context.Web;
                context.Load(web, website => website.Title);
                context.Load(web.Webs);

                CredentialCache cc = new System.Net.CredentialCache();
                cc.Add(new Uri(webSPOUrl), "NTLM", CredentialCache.DefaultNetworkCredentials);
                context.Credentials = cc;
                context.AuthenticationMode = ClientAuthenticationMode.Default;

                context.Load(web.Lists,
                    lists => lists.Include(list => list.Title,
                        list => list.Id));


                context.ExecuteQuery();
                Console.ForegroundColor = ConsoleColor.White;
                foreach (List list in web.Lists)
                {
                    Console.WriteLine("List title is: " + list.Title);
                }
                Console.WriteLine("");

            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error is: " + ex.Message);
        }
    }

谢谢大家，谁提供了解决方案。以下是工作代码：

public static void Uploadfiles(string SiteUrl, string DocLibrary, string ClientSubFolder, string FileName)
        {

            string webSPOUrl = "https://testdev.sharepoint.com/sites/test";
            Console.WriteLine("User Name:");
            string userName = "<your username >@testdev.onmicrosoft.com";
            Console.WriteLine("Password:");
            string librayName = "Documents";


                try
                {
                    using (var context = new SP.ClientContext(webSPOUrl))
                    {
                        // Sharepoint Online Authentication
                        context.Credentials = new SP.SharePointOnlineCredentials(userName, password);
                        SP.Web web = context.Web;

                        SP.FileCreationInformation newFile = new SP.FileCreationInformation();
                        byte[] FileContent = System.IO.File.ReadAllBytes(FileName);
                        newFile.ContentStream = new System.IO.MemoryStream(FileContent);
                        newFile.Url = Path.GetFileName(FileName);
                        SP.List DocumentLibrary = web.Lists.GetByTitle(DocLibrary);

                        SP.Folder Clientfolder = DocumentLibrary.RootFolder.Folders.Add(ClientSubFolder);

                        Clientfolder.Update();
                        SP.File uploadFile = Clientfolder.Files.Add(newFile);

                        context.Load(DocumentLibrary);
                        context.Load(uploadFile);
                        context.ExecuteQuery();
                        Console.ForegroundColor = ConsoleColor.Green;
                        Console.WriteLine("The File has been uploaded" + Environment.NewLine + "FileUrl -->" + SiteUrl + "/" + DocLibrary + "/" + ClientSubFolder + "/" + Path.GetFileName(FileName));
                     } }

【解决方案2】：

根据您提供的代码 sn-p，您似乎正在尝试连接到 SharePoint Online (O365)。您在代码中使用的网络凭据对象用于连接到传统的“本地”SharePoint 安装。你应该改用SharePointOnlineCredentials。

context.Credentials = new SharePointOnlineCredentials(userName,password);
context.Load(...);
context.ExecuteQuery();

【解决方案3】：

如果您可以提供用户名、密码和域，此代码对我有用：

var clientContext = new ClientContext(new Uri(someUrl))
{
    Credentials = new System.Net.NetworkCredential("UserName","Password", "DomainName")
}

如果您想在客户端访问本地 SharePoint 2013，您可以修改如下代码。

public void test()
{
    try
    {
        using (var context = new ClientContext(webSPOUrl))
        {
            context.Credentials = new NetworkCredential("username", "password", "domain");
            Web web = context.Web;
            context.Load(web, website => website.Title);
            context.Load(web.Webs);
            context.Load(web.Lists,
                lists => lists.Include(list => list.Title,
                    list => list.Id));

            context.ExecuteQuery();
            Console.ForegroundColor = ConsoleColor.White;
            foreach (List list in web.Lists)
            {
                Console.WriteLine("List title is: " + list.Title);
            }
            Console.WriteLine("");

        }
    }
    catch (Exception ex)
    {
        Console.WriteLine("Error is: " + ex.Message);
    }
}
