实际上这是个非常蛋疼的命题。它需要你有两个方面的能力:
1. 你实际RTF格式。
2. 你知道在OpenXml格式的文档中各种Style存在于哪个部份。
由于完整的RTF style非常多。我这里只写了一个最简单的例子,希望它能起排线的作用:
假设我有一个docx文档如下:
Hello!
This is a test text.
用Open Xml转换成RTF代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using SD = System.Drawing; using DocumentFormat.OpenXml.Packaging; using DocumentFormat.OpenXml.Wordprocessing; using com.mksword.Net.OpenXmlTools; using System.Text.RegularExpressions; namespace ConsoleApplication10 { class Class1 : WordprocessingDocumentUtil { private static Dictionary<char, int> map = new Dictionary<char, int>{ {'A',10},{'B',11},{'C',12},{'D',13},{'E',14},{'F',15},{'9',9}, {'8',8},{'7',7},{'6',6},{'5',5},{'4',4},{'3',3},{'2',2},{'1',1}, {'0',0}}; public void Action() { OpenedDocumentHandler(ConvertDoc2Rtf); } private bool ConvertDoc2Rtf(WordprocessingDocument WPD) { bool result = false; string source1 = "{\\rtf1\\ansi"; string colortable = null; int colorIndex = 0; string strsource = ""; MainDocumentPart MDP = WPD.MainDocumentPart; Document Doc = MDP.Document; foreach (Paragraph P in Doc.Descendants<Paragraph>().ToList()) { foreach (Run R in P.Descendants<Run>().ToList()) { if (R.RunProperties == null) { Text T = R.Descendants<Text>().FirstOrDefault(); strsource += T.Text; } else { RunProperties RPs = R.RunProperties; Color C = RPs.Descendants<Color>().FirstOrDefault(); Text T = R.Descendants<Text>().FirstOrDefault(); bool flag = false; if (C != null) { if (colortable != null) { colortable += RTFColorTable(C); } else { colortable = "\n{\\colortbl ;"; colortable += RTFColorTable(C); } colorIndex++; strsource += "\\cf" + colorIndex.ToString()+" "; flag = true; } Underline UL = RPs.Descendants<Underline>() .FirstOrDefault(); if (UL != null) { strsource += "\\ul " + T.Text + "\\ulnone"; } else { strsource += T.Text+ " "; } if (colortable != null && flag) { strsource += "\\cf0 "; } } } strsource += "\\par\n"; } if (colortable != null) { colortable += "}\n"; source1 += colortable + strsource + "\n}"; } else { source1 += strsource + "\n}"; } SetLog(source1, OXULogType.INFO); Clipboard.SetText(source1); return result; } private string RTFColorTable(Color Color) { string result = null; Regex regex = new Regex("([0-9 a-f A-F]{2})([0-9 a-f A-F]{2})" + "([0-9 a-f A-F]{2})"); Match match = regex.Match(Color.Val); result += "\\red" + Hex2Dec(match.Groups[1].Value); result += "\\green" + Hex2Dec(match.Groups[2].Value); result += "\\blue" + Hex2Dec(match.Groups[3].Value) + ";"; return result; } private string Hex2Dec(string Hex) { string result = null; char[] buffer = Hex.ToUpper().ToCharArray(); int r = 0; for (int i = 0; i < 2; i++) { r += i == 0 ? 16 * map[buffer[i]] : map[buffer[i]]; } result = r.ToString(); return result; } } }
