FileInfo.OpenText（）无法读取特殊字符EG UO° [英] FileInfo.OpenText() Fails To Read Special Characters E.G. üò°

问题描述

有中显示的字符在文本框和TextBlock的一些文本文件。

Have some text files that display many characters as � in TextBox and TextBlock.

我怎样才能正确地在.NET WPF读取并显示这些文件？

How can I properly read and display these files in .NET WPF?

文件读取其中Fi是一个FileInfo。

File read where fi is a FileInfo.

fileText = fi.OpenText().ReadToEnd();

在WPF我得到的字符üO°和其它特殊字符。

In WPF I get the � character for ü ò ° and other special characters.

尝试过多种字体。

文化是EN-EN。

如果我读文件作为流我得到的特殊字符

If I read the file as a Stream I get the special characters

System.IO.Stream fsIn = fi.OpenRead();
if (fsIn.Length == 0) return;
int curInt = -1;
StringBuilder sb = new StringBuilder();
while ((curInt = fsIn.ReadByte()) >= 0)
{
    sb.Append((char)curInt);
} 

OpenText公司（）似乎在阅读完所有的特殊字符为字节253

OpenText() appears to be reading all the special characters as byte 253

我觉得我学到的是文本不是UTF8 EN codeD。 UTF8采用128-255控制。 OpenText的（）用于UTF8编码。 WikiUFT8

What I think I have learned is the text is not UTF8 encoded. UTF8 uses 128-255 for control. OpenText() is used for UTF8 encoding. WikiUFT8

推荐答案

fi.OpenText 打开的StreamReader 与UTF8编码。如果你需要不同的编码，用这个来代替：

fi.OpenText opens a StreamReader with UTF8 encoding. If you need different encoding, use this instead:

using (var reader = new StreamReader(fi.FullName, Encoding.Unicode))
    fileText = reader.ReadToEnd();

当然，你实际上并不需要的的FileInfo 目标可言，因为只有路径正在由上面的调用。

Of course, you don't actually need the FileInfo object at all, as only the path is being used by the above call.
