ASP. Text encoding to UTF-8 text in Chinese characters

<summary>

Solve the text garbled all kinds of text encoding to UTF-8 text

<returns> New file path </returns>

public static string GetUtf8 (String fullpath,string savepath,string strnew)

{

Encoding e =getfileencodetype (FullPath);

System.IO.File.Create (Savepath). Close ();

using (StreamReader sr = new StreamReader (FullPath, E, false))

{

String utf8info = String. Empty;

Encoding UTF8 = Encoding.UTF8;

Convert the string into a byte[].

byte[] Unicodebytes = E.getbytes (sr. ReadToEnd ());

Perform. The conversion from one encoding to the other.

byte[] Asciibytes = Encoding.convert (E, UTF8, unicodebytes);

Convert the new byte[] into a char[] and then into a string.

This was a slightly different approach to converting tillustrate

The use of Getcharcount/getchars.

char[] Asciichars = new Char[utf8. GetCharCount (asciibytes, 0, Asciibytes.length)];

UTF8. GetChars (asciibytes, 0, Asciibytes.length, asciichars, 0);

Utf8info = new String (asciichars);

using (StreamWriter SW = new StreamWriter (Savepath, False, Encoding.UTF8))

{

Sw. Write (Utf8info);

}

}

System.IO.File.Delete (FullPath);

System.IO.File.Copy (savepath,strnew,true);

System.IO.File.Delete (Savepath);

return strnew;

}

Method 2

using (FileStream fs = new FileStream (FullPath, FileMode.Open))

{

using (StreamReader sr = new StreamReader (Fs,encoding.default))

{

while (!SR. Endofstream)

{

String sline = Sr. ReadLine ();

StringBuilder B = new StringBuilder ();

B.appendline (sline);

Save to another TXT file

Using (Streamwritersw=system.io.file.appendtext (Savepath))

{

string n = b.tostring ();

Sw. WriteLine (Sline.tostring ());

}

}

}

}

System.IO.File.Delete (FullPath);

string strnewfile = FullPath;

System.IO.File.Copy (Savepath, strNewFile, true);

System.IO.File.Delete (Savepath);

using (StreamReader sr = new StreamReader (Strnewfile,encoding.default, False))

//{

using (StreamWriter SW = new StreamWriter (FullPath, Falsencoding.utf8))

//    {

Sw. Write (Server.HTMLEncode (Sr. ReadToEnd ()));

//    }

//}

System.IO.File.Delete (strNewFile);

FileInfo filenew = new FileInfo (strnewfile);

Sourcesfile.file_size = Filenew.length;

This.sourcesFileService.Save (Sourcesfile);
