Question

我以前使用的是GetFileByServerRelativeUrl，但工作正常，但是GetFileByServerRelativePath应该支持字符＃和％，因此我按如下所示更改了代码，但现在却不起作用带有任何文件？

public bool DownloadFile(string filepath, out string     Base64EncodedFile, out string errormessage)
        {
            Base64EncodedFile = string.Empty;
            errormessage = string.Empty;

            try
            {
                Uri filename = new Uri(filepath);                
                string serverrelative = filename.AbsolutePath;

                //This old method does not support # or % but works fine
                //Microsoft.SharePoint.Client.File file = context.Web.GetFileByServerRelativeUrl(serverrelative);

                // >> Replaced with this
                ResourcePath filePathDecoded = ResourcePath.FromDecodedUrl(serverrelative);
                Microsoft.SharePoint.Client.File file = context.Web.GetFileByServerRelativePath(filePathDecoded);
                // << Replaced with this

                context.Load(file);
                ClientResult<System.IO.Stream> streamResult = file.OpenBinaryStream();
                context.ExecuteQuery();

                Base64EncodedFile = ConvertToBase64(streamResult.Value);            
                return true;
            }
            catch (Exception ex)
            {
                errormessage = ex.Message;
                return false;
            }
        }

SharepointClient.SharepointClient newupload = new SharepointClient.SharepointClient("https://xxxxxxx.sharepoint.com/sites/xxxxxxxxx/", usernametext.Text, textpassword.Text);

            newupload.DownloadFile(Url.Text, out EncodedAbs, out errormessage);

如果我使用旧的GetFileByServerRelativeUrl可以正常工作...我尝试了所有操作，但似乎无法正常工作GetFileByServerRelativePath ...我不明白自己在做什么错？？

请帮助！！！

太好了！谢谢您的示例，我的眼睛睁开了，我发现我的代码唯一的问题是我传递的URL中包含编码的HTML字符！！！我将空格传递为％20，这引起了问题！！！一旦我删除％20并替换为空格，一切都很好！这是有道理的，因为FromDecodedUrl实际上再次对％20进行了编码，导致URL无效！

GetFileByServerRelativePath不起作用，并且始终返回未找到的文件
