推荐答案
以下是几个样本。示例A是一个简单的类，它将存储西里尔文输出并在中返回使用字符串ToString（）覆盖。如果你想使用StringReader类你总是从StringReader c>如例B所示。
例A：
Here are a couple samples. Example A is a simpleclassthat will store the cyrillic output and return thestringin theToString()usingoverride. If you want to useStringReader classyou could alwaysinheritfromStringReaderas shown in Example B.
Example A:
public class MyStringReader
{
private String str;
private Encoding encoding = Encoding.UTF8;
public Encoding Encoding
{
get
{
return this.encoding;
}
set
{
if (value != null)
{
this.encoding = value;
}
}
}
public MyStringReader(string str)
{
this.str = this.encoding.GetString(this.encoding.GetBytes(str));
}
public override string ToString()
{
return this.str;
}
}
例B：
Example B:
public sealed class CyrillicTextReader : StringReader
{
public CyrillicTextReader(string text)
: base(LoadCyrillicText(text))
{
}
private static string LoadCyrillicText(string text)
{
return Encoding.UTF8.GetString(Encoding.UTF8.GetBytes(text));
}
}
我修复它:)））））最后下面的代码完美无缺。主要问题是它需要一个字体
I fix it :))))) finally the code below works perfectly. The main problem was that it needed a font
string html = @"<html><body><img src='C:/Users/Kosta/Desktop/Vmedia Own Projects/Prodavnicata/eMall/Dodatoci za Master/images/logo.png' alt='Smiley face' height='42' width='42'><table><tr><td><p style='font-size: 10pt; font-family: Times'>" +
"Cher Monsieur,</p><br><p>" +
"КОСТА<br></p><p align='justify' style='text-indent: 2em; font-size: 10pt; font-family: Times'>" +
"En vous remerciant à nouveau de la confiance que vous nous témoignez,</p>" +
"<br><p style='font-size: 10pt; font-family: Times'>Bien Cordialement,<br>" +
"<br>ADMINISTRATEUR ADMINISTRATEUR<br>Ligne directe : 04 42 91 52 10<br>Acadomia® – " +
"37 BD Aristide Briand – 13100 Aix en Provence </p></td></tr></table></body></html>";
FontFactory.Register("c:/windows/fonts/ARIALUNI.TTF");
StyleSheet style = new StyleSheet();
style.LoadTagStyle("body", "face", "Arial Unicode MS");
style.LoadTagStyle("body", "encoding", BaseFont.IDENTITY_H);
using (Document document = new Document())
{
PdfWriter pdfWriter = PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\Invoice_Statement.pdf", FileMode.Create));
document.Open();
foreach (IElement element in HTMLWorker.ParseToList(
new StringReader(html.ToString()), style))
{
document.Add(element);
}
}
