拆分long String In C# 到Array，返回第一个元素为空？

Question

I have a log file with some lines:

test123 (random text..)
test123 (random text..)
test123 (random text..)

I want to convert it into an array, so I did the following:

string[] myArray = logFileText.Replace("test123", "#test123").Split("#");

This work fine except for the fact that the first element in myArray is empty.. any idea how to solve this?

Note: cannot use Environment.NewLine, it does not work on this file for some reason..

Answer 1

As @pm100 said, this is the answer:

Split('#', StringSplitOptions.RemoveEmptyEntries)

Answer 2

You could add a .Skip(1) to the end of your code:

string[] myArray = logFileText.Replace("test123", "#test123").Split("#").Skip(1).ToArray();

Answer 3

You need to read the file line-by-line. This should work

  var filePath = "D:\\MyLogfile.txt";

        var fileContents = File.ReadAllLines(filePath); //Reads line by line
        if (fileContents.Length > 0) //If file has any lines/content
        {
            var myFileContents = fileContents.Skip(1); //Skips the first row

            foreach (var fileLine in myFileContents) //Process line by line
            {
                
            }
        }
