この便利な関数を使用して xml ドキュメントを「美しく」し、インデントと改行でフォーマットしました。しかし、より大きなドキュメント (~1MB) では、何らかの理由で doc.Save(writer) で OutOfMemoryException が発生します。この問題を解決するにはどうすればよいですか?
public static string BeautifyXmlDocument(XmlDocument doc)
{
MemoryStream sb = new MemoryStream();
XmlWriterSettings s = new XmlWriterSettings();
s.Indent = true;
s.IndentChars = " ";
s.NewLineChars = "\r\n";
s.NewLineHandling = NewLineHandling.Replace;
s.Encoding = new UTF8Encoding(false);
XmlWriter writer = XmlWriter.Create(sb, s);
doc.Save(writer);
writer.Close();
return Encoding.UTF8.GetString(sb.ToArray());
}
