问题描述
我有一个文本文件，每天都有，并且该文件具有非Ascii字符。我需要使用文本键盘检查文件，找到非ascii字符，然后使用字母表删除这些字符。有没有办法用C sharp自动进行检查？
提前谢谢
I have a text file and which comes everyday and that file is having non- Ascii characters . I need to check the file using text pad and find the non ascii characters and I removed those characters using Alphabets. Is there any possible way using C sharp to do this checking automatically ?
Thanks in advance
推荐答案
byte[] bytes = File.ReadAllBytes(@"D:\Temp\inputfile.bin");
byte[] outp = bytes.Where(c => c <= 127).ToArray();
File.WriteAllBytes(@"D:\Temp\outputfile.txt", outp);
哪个字符会丢弃整个ASCII范围之外的字符，但你可能想要限制更多：
Which throws away characters outside the full ASCII range, but you probably want to restrict is somewhat more:
byte[] bytes = File.ReadAllBytes(@"D:\Temp\inputfile.bin");
byte[] outp = bytes.Where(c => c >= 32 && c < 127).ToArray();
File.WriteAllBytes(@"D:\Temp\outputfile.txt", outp);
这也会丢弃所有ASCII控制代码，只留下可打印的字符。但这可能不是你所需要的，因为（我猜）你需要保留一些控制代码 - 我不知道哪些：这是你的应用程序！
Which discards all ASCII control codes as well, and just leaves printable characters. But that probably isn't exactly what you need, since (I'm guessing) you need to keep some of the control codes - which ones I don't know: it's your application!
