Question

我需要从sharepoint下载excel文件到本地系统。我写了下面的方法。

    internal static void DownloadFilesFromSharePoint(string siteUrl, string folderPath, string tempLocation)
    {
        ClientContext ctx = new ClientContext(siteUrl);
        ctx.Credentials = new NetworkCredential("username", "password");

        FileCollection files = ctx.Web.GetFolderByServerRelativeUrl(folderPath).Files;

        ctx.Load(files);
        ctx.ExecuteQuery();----FAILED HERE

        foreach (File file in files)
        {
            FileInformation fileInfo = File.OpenBinaryDirect(ctx, file.ServerRelativeUrl);
            ctx.ExecuteQuery();

            var filePath = tempLocation + file.Name;
            using (var fileStream = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
            {
                fileInfo.Stream.CopyTo(fileStream);
            }
        }
    }

要调用上述方法，我在Main方法中有以下内容：

    public static void Main()
    {
    Program.DownloadFilesFromSharePoint("http://sp.frk.com/teams/ResearchSystemsSupport/GT%20Resources/Forms/AllItems.aspx", "/TeamDocuments", @"c:\");

    }

但是上面的代码不起作用。我已经在调试时标记了代码给出异常的地方（标记为---- FAILED HERE）。任何人都可以在这里指出问题。有人可以帮我吗。如果可以的话，请给我详细的解释。

Answer 1

替换下面的代码

Program.DownloadFilesFromSharePoint("http://sp.frk.com/teams/ResearchSystemsSupport/GT%20Resources/Forms/AllItems.aspx", "/TeamDocuments", @"c:\");

与

Program.DownloadFilesFromSharePoint("http://sp.frk.com/teams/ResearchSystemsSupport", "GT%20Resources/TeamDocuments", @"c:\");

网站网址和文件夹路径不正确。

我终于找到了下面粘贴的有效代码。正如LZ_MSFT的评论所指出的那样，我重新检查了我正在传递的共享点链接，但他们错了，因此对其进行了更改并使其起作用。还在网络凭据中，添加了域。

    static void DownloadFilesFromSharePoint(string siteUrl, string siteFolderPath, string localTempLocation)
    {
        ClientContext ctx = new ClientContext(siteUrl);
        ctx.Credentials = new NetworkCredential("username", "password", "Domain");

        FileCollection files = ctx.Web.GetFolderByServerRelativeUrl(siteFolderPath).Files;

        ctx.Load(files);
        if (ctx.HasPendingRequest)
        {
            ctx.ExecuteQuery();
        }

        foreach (File file in files)
        {                
                FileInformation fileInfo = File.OpenBinaryDirect(ctx, file.ServerRelativeUrl);
                ctx.ExecuteQuery();

                var filePath = localTempLocation + "\\" + file.Name;
                System.IO.FileStream fileStream = new System.IO.FileStream(filePath, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.ReadWrite, System.IO.FileShare.ReadWrite);

                fileInfo.Stream.CopyTo(fileStream);

        }
    }

调用功能：

    static void Main(string[] args)
    {
        Program.DownloadFilesFromSharePoint(@"http://sp.frk.com/teams/ResearchSystemsSupport", @"http://sp.frk.com/teams/ResearchSystemsSupport/Global%20Equity%20Group/Daily_Checks", @"C:\Temp");       
    }

使用C＃将Excel文件从SharePoint网站下载到本地系统
