Encoding Question

[Guest]

I try to write a ASP.Net web application which will post data to other
websites

I'm use NameValueCollection class add(...) method and WebClient class
uploadvalue(...) method to post data to other website. It works fine if
the data is in English, however, when it contain characters in other
languages (such as Chinese big5), it will display some un-readable
characters.

In web.config file I set encoding to "big5"
<globalization fileEncoding="big5" requestEncoding="big5"
responseEncoding="big5" />

In aspx page html I set codePage to "950"
<%@ Page Language="vb" validateRequest="false" AutoEventWireup="false"
Codebehind="message_post.aspx.vb" Inherits="message_post.WebForm1"
codePage="950" %>

If anyone knows how to solve this problem, please let me know .. Thanks ..

<globalization /> has no effect on WebClient. WebClient.UploadValues() in
..NET 1.1 always uses UTF-8 internally. If you want to use a different
encoding like Big5, you'll need to use WebRequest or WebClient.UploadData(),
and perform the encoding manually:

public void UploadValues(string url, NameValueCollection data, string
encoding) {
Encoding enc = Encoding.GetEncoding(encoding);
StringBuilder builder = new StringBuilder();
foreach (string name in data) {
string encodedName = HttpUtility.UrlEncode(name, enc);
string encodedValue = HttpUtility.UrlEncode(data[name], enc);
builder.Append(encodedName);
builder.Append('=');
builder.Append(encodedValue);
builder.Append('&');
}
builder.Remove(builder.Length - 1, 1);
byte[] bytes = Encoding.ASCII.GetBytes(builder.ToString());
WebClient client = new WebClient();
client.Headers["Content-Type"] = String.Format(
"application/x-www-form-urlencoded; charset={0}",
encoding);
byte[] response = client.UploadData(url, bytes);
// Do something with the response...
}
