c# - 例外：“不支持 URI 格式”

Question

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

但是，当我尝试将其放入DirectoryInfoctor 时，我得到“不支持 URI 格式”异常。

我用谷歌搜索并查看了 SO，但我只看到远程路径的解决方案，而不是本地路径。我期望某种转换方法...

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()) 解决了同样的错误，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 { }
