如何使用.NET 4.0讀取.RTF文件

Question

我見過使用Word 9.0對象庫的示例。但是我在VS2010中安裝了Office 2010 Beta和.NET 4.0。有關如何使用新的Word Dll的任何提示？

所以我只是想在.NET3.5或更高版本中將RTF的功能轉換爲TEXT。

Answer 1

我使用TextRange獲得了WPF的更好解決方案。

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); 
} 

現在你可以看到所提取的文本內documentTextRange.Text

你真的很新來加載.RTF到Word嗎？ .net具有可處理.RTF文件的RichTextBox控件。請參閱：http://msdn.microsoft.com/en-us/library/1z7hy77a.aspx（如何：將文件加載到Windows窗體RichTextBox控件中）
