问题描述

我需要使用VB.NET将UTF8字符串转换为ISO-8859-1字符串。

I need to convert UTF8 string to ISO-8859-1 string using VB.NET.

任何示例?

强调的文字我尝试了拉丁语功能,但没有运行。我收到不正确的字符串。

emphasized textI have tried Latin function and not runs. I receive incorrect string.

我的例子是我需要使用API​​发送短信。

My case is that I need to send SMS using API.

此代码:

        baseurl = "http://www.myweb.com/api/sendsms.php"
        client = New WebClient
        client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)")
        client.Encoding = System.Text.Encoding.GetEncoding("ISO-8859-1")
        client.QueryString.Add("user", user)
        client.QueryString.Add("password", pass)
        client.QueryString.Add("alias", myAlias)
        client.QueryString.Add("dest",  mobile)
        textoSms = Me.mmTexto.Text
        textoSms = System.Web.HttpUtility.UrlEncode(textoSms)
        client.QueryString.Add("message", textoSms)
        data = client.OpenRead(baseurl)
        reader = New StreamReader(data)
        s = reader.ReadToEnd()
        data.Close()
        reader.Close()

但不运行...我收到不正确的消息。例如

But not runs...I receive incorrect messages. For example

如果我写:mañana返回 maa ana

如果我写aigüa返回 aiga

推荐答案

about:

Dim converted as Byte() = Encoding.Convert(utf8, Encoding.UTF8, _
                                           Encoding.GetEncoding(28591))

假设当你说UTF8 string是一些文本的UTF-8表示。如果您还有其他意见,请指明:)

That assumes that when you say "UTF8 string" you mean "binary data which is the UTF-8 representation of some text". If you mean something else, please specify :)

请注意,ISO-8859-1仅代表完整Unicode的一小部分。 IIRC,你会得到?对于ISO-8859-1中不可用的源数据中的任何字符。

Note that ISO-8859-1 only represents a tiny proportion of full Unicode. IIRC, you'll end up with "?" for any character from the source data which isn't available in ISO-8859-1.
