In the following example I m getting a response from the server; however do I need to set ASCII or UTF8 encoding type ?
Dim objURI As Uri = New Uri(URL)
Dim wReq As WebRequest = WebRequest.Create(objURI)
Dim wResp As WebResponse = wReq.GetResponse()
Dim respStream As Stream = wResp.GetResponseStream()
Dim reader As StreamReader = New StreamReader(respStream, Encoding.ASCII)
Dim respHTML As String = reader.ReadToEnd()
wResp.Close()
这确实取决于网络服务器在发送答复时的编码。
The character encoding is set by the encoding parameter, and the buffer size is set to 1024 bytes. The StreamReader object attempts to detect the encoding by looking at the first three bytes of the stream. It automatically recognizes UTF-8, little-endian Unicode, and big-endian Unicode text if the file starts with the appropriate byte order marks.
象你一样,对我来说,那应该是安全的,让跑时间承认ding。
这取决于您对服务器的期望。 就超文本而言(看来是您的期望),ASCII运行了99%的英文页时间,并允许你将所有超文本内容编码,而不管怎样。 然而,你应做的第一批事情之一是在文件标题中读到任何“金属”标签;这些内容将具体指明案文在体内的编码。 通常,如果这是ASCII,那么UTF-8就会落后于ASCII(但会显示出2-byte和4-byte的特性)。
