朋友們,我可以通過單字節獲取XML文件,也許這是一個問題。你可以建議我採用替代方法來做同樣的事情來保存XML文件嗎?如何使用vb.NET從URL讀取XML數據並保存
Try
Dim strUrl As String = "http://example.com"
Dim wr As HttpWebRequest = CType(WebRequest.Create(strUrl), HttpWebRequest)
Dim ws As HttpWebResponse = CType(wr.GetResponse(), HttpWebResponse)
ws.ContentType = "UTF-16"
Dim str As Stream = ws.GetResponseStream()
Dim inBuf(100000) As Byte
Dim bytesToRead As Integer = CInt(inBuf.Length)
Dim bytesRead As Integer = 0
While bytesToRead > 0
Dim n As Integer = str.Read(inBuf, bytesRead, bytesToRead)
If n = 0 Then
Exit While
End If
bytesRead += n
bytesToRead -= n
End While
Dim fstr As New FileStream("c:/GetXml.xml", FileMode.OpenOrCreate, FileAccess.Write)
fstr.Write(inBuf, 0, bytesRead)
str.Close()
fstr.Close()
Catch ex As WebException
Response.Write(ex.Message)
End Try
