解析日志文件时如何获取或设置值 [英] How to get or set value while parsing a log file

问题描述

我正在尝试从我的应用程序中的RoboCopy方法产生的日志文件中获取文件复制数量的值.日志文件始终采用以下格式:

Hi I am trying to get the number of files copied value from a logfile produce by a RoboCopy method within my application. The logfile is always in this format:

到目前为止，我已经能够将文件读入流读取器中，但是有什么我可以做的以确保我总是选择Files的最后一个实例:然后选择Total列下的值，即1

So far I am able to read the file into a streamreader but is there anything I can do to ensure I am always selecting the last instance of Files : and then the value under the Total column i.e. 1

try
{
// Open file for reading.
using (StreamReader r = new StreamReader(@"C:\LogFile.log"))
{
    // 2.
    // Read each line until EOF.
    string line;
    while ((line = r.ReadLine()) != null)
    {
        // 3.
        // Do stuff with line.
        if (line.Contains("Files"))
        {
            String content = line.ToString();
            char sep = '\t';
            string[] splitContent = content.Split(sep);
            Console.WriteLine(splitContent);
        }                        
    }
}
}
catch (Exception)
{

throw;
}

最小输出= System.String []

Output at the min = System.String[]

推荐答案

您只需要在数组中选择 second 项，即

You just need to select the second item in the array i.e.

Console.WriteLine(splitContent[1]);

考虑一下，您的行数据看起来像

Think about it, your line data looks like

Files :\t1\t1\t0\t0\t0\t0

调用content.Split(sep)时，您的数组将如下所示:

When you call content.Split(sep) your array will look like

0: "Files :"
1: "1"
2: "1"
3: "0"
4: "0"
5: "0"
6: "0"

因此，如果您根据列进行映射，则始终希望提取位于索引1(0为标签列)的Total列.

So if you map this in terms of columns you always want to pull the Total column which is at index 1 (0 being the label column).

您甚至可以在此处使用Emem来提高可读性，例如

You could even use an emum here for readability e.g.

enum Columns
{
    Label,
    Total,
    Copied,
    Skipped,
    Mismatch,
    Failed,
    Extra
}

...
string[] rowData = content.Split('\t');
Console.WriteLine(rowData[(int)Columns.Total]);

或使用const避免强制转换

const int TotalCol = 1;

...
string[] rowData = content.Split('\t');
Console.WriteLine(rowData[TotalCol]);
