如何使用.NET 4.0读取.rtf文件

.net-4.0 interop .net-3.5 wpf c#

Jobi Joy · 技术社区 · 14 年前

我看到过使用Word 9.0对象库的示例。但是我在VS2010中有Office2010测试版和.NET 4.0。关于如何使用新单词dlls有什么建议吗?

所以我只想用.net3.5或更高版本获得RTF到文本的功能。

我得到了一个更好的WPF解决方案,使用文本范围。

FlowDocument document = new FlowDocument();

//Read the file stream to a Byte array 'data'
TextRange txtRange = null;

using (MemoryStream stream = new MemoryStream(data))
{
    // create a TextRange around the entire document
    txtRange = new TextRange(document.ContentStart, document.ContentEnd);
    txtRange.Load(stream, DataFormats.Rtf);
}

现在,您可以在documenttextfrange.text中看到提取的文本。

你真的是新来加载.rtf到Word吗?.NET具有可以处理.rtf文件的RichTextBox控件。请参见这里: http://msdn.microsoft.com/en-us/library/1z7hy77a.aspx (如何:将文件加载到Windows窗体RichTextBox控件中)
