Convert Text Encoding

Web Program When obtaining the access source, some URLs are garbled. For example, Baidu adopts the gb2312 encoding method when searching for Chinese characters, while Google and other search engines use utf8 encoding, the encoding method used by your website is utf8. garbled characters are displayed when Baidu's access source contains Chinese characters. Therefore, you can change the URL encoding of Baidu's access source to utf8.
When you browse the. NET class library reference, you will find that there is an encoding. Convert () static method. You do not need to know the encoding method of the internal machine code for encoding conversion.

The procedure is as follows:UsingSystem;
UsingSystem. IO;
UsingSystem. text;

Namespace Encodingtest
{
Class Program
{
Static Void Main ( String [] ARGs)
{
Try
{
Encoding utf8 = Encoding. utf8;
Encoding GB = Encoding. getencoding ( " Gb2312 " );

String Gb_string = File. readalltext ( " C: \ gb2312_file.txt " , Encoding. Default );
Byte [] Gb_bytes = GB. getbytes (gb_string );
Byte [] Utf8_bytes = Encoding. Convert (GB, utf8, gb_bytes ); // Conversion Encoding
Int Length = Utf8.getcharcount (utf8_bytes, 0 , Utf8_bytes.length );
Char [] Utf8_chars = New Char [Length];

Utf8.getchars (utf8_bytes,0, Utf8_bytes.length, utf8_chars,0);

StringUtf8_string= New String(Utf8_chars );

// File. Create ("C: \ utf8_file.txt ");
File. writealltext ( " C: \ utf8_file.txt " , Utf8_string, utf8 );
}
Catch (Exception ex)
{
Console. Write (ex. Message );
Console. readkey ();
}
}
}
