问题描述
我正在使用Richtextbox来显示不同的* .rtf文件.通常，这很好.但是有些文件很奇怪 问题出现了.当将它们加载到RichTextBox中时，会出现错误5无效的文件格式". (原始消息以德语显示，也许原始英语消息会有所不同.
i am using a richtextbox for displaying different *.rtf files. Normally this is working just fine. But with some files a strange problem is arising. When loading them into the richtextbox there is Error 5 "invalid file format" (the original message is shown in german language, maybe the original english message would be slightly different.
当查看rtf文件时(即通过将其加载到记事本中)，它看起来确实像是一种绝对奇怪的编码.某物 像
When looking into the rtf file (i.e by loading it into the notepad) it really seems like an absolutely strange encoding. Something like

我尝试使用以下代码将一个奇怪的rtf文件打开到文本框中(通常适用于所有类型的文件)
Dim ecode As Encoding = Encoding.UTF7
bTXT = IO.File.ReadAllBytes(sViewFile)
textbox.text = ecode.GetString(bTXT)
bTXT = IO.File.ReadAllBytes(sViewFile)
textbox.text = ecode.GetString(bTXT)
但即使在 尝试所有现有的 代码页(很多)，根本没有一个代码页可以正常工作.最奇怪的事情:当我尝试使用MSWord或旧的写字板打开奇怪的rtf文件时，它们看起来绝对是正常的.
but even after trying all existing Codepages (which are quite a lot) there was not one Codepage which worked at all. the strangest thing: When i try to open the strange rtf-files with MSWord or old WordPad they look absolutely normal.
有人知道这个* rtf文件有什么问题吗? 任何想法我都能够使它们在richtextbox?
Does anybody know what is ‘wrong’ with this *rtf files ? Any idea how I could be able to make them readable inside an richtextbox ?
非常感谢您的任何答复

推荐答案
但是对于某些文件，会出现一个奇怪的问题.将它们加载到RichTextBox中时，会出现错误5无效的文件格式"
文件已压缩. RTF文件应为纯文本，并按照您的示例显示RTF代码序列.您正在查看的文件不是纯文本，也不会作为RTF处理.您应该回到找到文件的位置，然后 查看您需要使用它做什么，例如将其解压缩以访问RTF内容(如果确实如此).
The files are compressed. A RTF file should be plain text, with RTF code sequences as per your example. The file that you're looking at is not plain text, and will not process as RTF. You should go back to wherever you found the file and see what you need to do with it, for instance unzipping it, to get access to the RTF content (if that's what it really is).
