是否可以从URL读取到System.IO.Stream对象？

Question

我试图从一个url读取到System.IO.Stream对象.我试着用

Dim stream as Stream = New FileStream(msgURL, FileMode.Open)

但我得到一个错误,FileStream对象不支持URI格式.是否有一些我可以使用的方法继承自System.IO.Stream能够从URL读取？

Answer 1

用途WebClient.OpenRead:

Using wc As New WebClient()
    Using stream As Stream = wc.OpenRead(msgURL)
        ...
    End Using
End Using

Answer 2

VB.Net:

Dim req As WebRequest = HttpWebRequest.Create("url here")
Using stream As Stream = req.GetResponse().GetResponseStream()

End Using

C#:

var req = System.Net.WebRequest.Create("url here");
using (Stream stream = req.GetResponse().GetResponseStream())
{

}
