C#实现将Doc文档转换成rtf格式的方法示例

using System;namespace DocConvert{ class DoctoRtf { static void Main() {  //创建一个word的实例  Word.application newApp = new Word.Application();  // 指定源文件和目标文件  object Source="c://abc//Source.doc";  object Target="c://abc//Target.rtf";  object Unknown =Type.Missing;  // 打开要转换的Word文件  newApp.Documents.Open(ref Source,ref Unknown,  ref Unknown,ref Unknown,ref Unknown,  ref Unknown,ref Unknown,ref Unknown,  ref Unknown,ref Unknown,ref Unknown,  ref Unknown );  // 指定文档的类型  object format = Word.WdSaveFormat.wdFormatRTF;  //改变文档类型  newApp.ActiveDocument.SaveAs(ref Target,ref format,  ref Unknown,ref Unknown,ref Unknown,  ref Unknown,ref Unknown,ref Unknown,  ref Unknown,ref Unknown,ref Unknown);  //关闭word实例  newApp.Quit(ref Unknown,ref Unknown,ref Unknown); } }}
