Imports
Public Class Form1
    Private Function GetUrlFileText(ByVal FileUrl As String) As String
          'FileUrl 是你要读取的远程文件的完整路径,如: https://bbs.bccn.net/Temp/Text.txt
        Dim MyUrl As New Uri(FileUrl)
        Dim MyQuest As WebRequest = WebRequest.Create(MyUrl)
        Dim resp As WebResponse = MyQuest.GetResponse()
        Dim MyStr As Stream = resp.GetResponseStream()
        Dim read As StreamReader = New StreamReader(MyStr, System.Text.Encoding.Default)
        Dim tmpStr As String = read.ReadToEnd
        read.Close()
        Return tmpStr
    End Function
End Class
