Stream Reader Readline检测换行符 [英] Stream Reader Readline detect newline characters

问题描述

我正在尝试从日志文件中的每一行文本中删除所有换行"字符.

I'm trying to remove any "new line" characters from each line of text in my log file.

以下是我正在使用Stream Reader读取的示例条目:-

Below is an example entry that I am reading in with a Stream Reader :-

<![LOG[Raising event:
[SMS_CodePage(850), SMS_LocaleID(2057)]
instance of SoftDistProgramStartedEvent
{
    AdvertisementId = "000216F6";
    ClientID = "GUID:B55C2757-CBAE-468E-B54F-46CAF2ECF68F";
    CommandLine = "\"C:\\WINNT\\system32\\cscript.exe\" /nologo Shutdown_Desktops_Overnight.vbs";
    DateTime = "20130211080211.784000+000";
    MachineName = "DWD*****";
    PackageName = "0000073C";
    ProcessID = 2516;
    ProgramName = "Shutdown Desktops Overnight";
    SiteCode = "S00";
    ThreadID = 3640;
    UserContext = "NT AUTHORITY\\SYSTEM";
    WorkingDirectory = "C:\\WINNT\\system32\\CCM\\Cache\\0000073C.1.System\\";
};
]LOG]!><time="08:02:11.800+000" date="02-11-2013" component="execmgr" context="" type="1" thread="3640" file="event.cpp:522">

在实际的日志文件中，该文件在文件中显示为一行，而新行字符"(New Line Characters)替换为一个正方形.

In the actual Logfile this is displayed as one line in the file, with the "New Line Characters" replaced with a square.

我正在使用以下代码读取日志条目:-

I'm using the following code to read in the log entries :-

using (StreamReader sr = new StreamReader(@"C:\Documents and Settings\riversd\Desktop\Logfile2.log"))
        {
            string Line;

            while ((Line = sr.ReadLine()) != null)
            {

            }
        }

问题在于，当StreamReader从txt文件读取此条目时，它会在以下位置中断:-

The issue is that when the StreamReader reads this entry from the txt file it breaks at :-

"<![LOG[Raising event:"

我需要即时删除此条目中的所有换行符.我不想将整个文件读到内存中然后再删除它们，我宁愿在读取每个日志时对其进行处理.

I need to remove all new line characters in this entry, on the fly. I don't want to read the entire file into memory and then remove them, I'd rather deal with each log as I read it.

有可能吗?

推荐答案

sr.ReadLine().Replace(Environment.NewLine, String.Empty);

如果行尾不是 \ r \ n 而是 \ n ，则可以使用正则表达式:

In case the end of line is not \r\n but \n you can use regex:

Line = Regex.Replace(sr.ReadLine(), @"(\r\n|\n)", String.Empty);
