例外：“不支持URI格式”

Question

我有一个指向dir的绝对本地路径："file:\\C:\\Users\\john\\documents\\visual studio 2010\\Projects\\proj"

但是当我尝试将它扔进DirectoryInfo的ctor时，我得到了“不支持URI格式”的例外。

我用Google搜索并查看了SO，但我只看到了远程路径的解决方案，而不是本地解决方案。我期待某种转换方法......

Answer 1

string uriPath =
    "file:\\C:\\Users\\john\\documents\\visual studio 2010\\Projects\\proj";
string localPath = new Uri(uriPath).LocalPath;

Answer 2

试试这个

ImagePath = "http://localhost/profilepics/abc.png";
   HttpWebRequest request = (HttpWebRequest)WebRequest.Create(ImagePath);
          HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream receiveStream = response.GetResponseStream();

Answer 3

我用Path.Combine（MapPath（））解决了相同的错误，以获取物理文件路径而不是http:/// www。

Answer 4

     string ImagePath = "";

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(ImagePath);
        string a = "";
        try
        {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
            Stream receiveStream = response.GetResponseStream();
            if (receiveStream.CanRead)
            { a = "OK"; }
        }

        catch { }
