Question

I’m trying to figure out how to find a certain string and display how many lines down it is in a text file.

For example let’s saying I’m trying to find the string “I’m a string” in a text file then also have the location of the string(As in lines down) recorded in a variable.

Anyone got any tips too accomplish this?

Thanks

First, I would read in the file, then loop through each line searching for the text. Something like…

string[] lines = System.IO.File.ReadAllLines(@"C:\file.txt");

int count = 0;
foreach (string line in lines)
{
    count++;
    if (line.indexOf("I'm a string") > -1) {
       // found it
    }    

}
