ReadAllText and reading a textfile into a string

I want to read a textfile into a string. The problem is that I need a CrLf character at the end of each line.

It is supposed to be already there if it is in your source file.

I read a large file, >150 Mega, with ReadAllText. This file is a .txt file, with linebreaks. Then  I am using Regex to find the lines that start with STOP. There are multiple lines that start with STOP. But it will only find the first one. It is not an error of Regex, but just, the result is only one line.

I know I can use a StreamReader, but that is rather slow. I want ReadAllText, but that it keeps the linebreakw. StreamReader is just too slow;

Any reason to load such a big file all at once?

Have you tried your regex on a much smaller file? Might be a buffer overrun with the regex.

I am searching those files.

It has to do with the end of line characters. Or I presume that that is the problem. Because if I look for a string inside the file, on any position, it works. Only if I am looking for leading strings, I have that problem

I found it myself. It is required to use the option 'multiline', and then it works. Thanks for your time.
