試圖FTP以特殊字符

Question

文件我的代碼：

FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(url); 
request.Method = WebRequestMethods.Ftp.DownloadFile; 
request.UseBinary = true; // Binary mode when downloading 
request.Credentials = new NetworkCredential(user, password); 
FtpWebResponse response = (FtpWebResponse)request.GetResponse(); 

我總是得到錯誤：「請求的URI是這個FTP命令無效」。

問題是url包含一個「＃」。既然我不能阻止人們創建這種類型的文件，是否有辦法逃避特殊字符並仍然處理文件？

Answer 1

做一個字符串"#" ->"%23"
URL編碼替換不應包含哈希因爲：

Some characters present the possibility of being misunderstood within URLs for various reasons. These characters should also always be encoded.

Answer 2

您可以使用HttpUtility.UrlEncode編碼的特殊字符。
