At least try to do it yourself. and publish your code when you are stuck.
Advice: Do basic research about your problem before asking.

See this:

http://lmgtfy.com/?q=how+to+read+text+from+a+text+file+line+by+line+in+c%23

There are a couple of ways: The StreamReader class has a ReadLine method for example.
But the simplest way is to read the lot at once:
C#
string[] lines = File.ReadAllLines(@"D:\Temp\MyFile.txt");
foreach (string line in lines)
   {
   Console.WriteLine(line);
   string result = DoSomething(line);
   Console.WriteLine(result);
   }

You're welcome!
Use File.Open[^] to get a stream

Create an instance of StreamReader[^] for that stream.

Use ReadLine[^] method to read the file line by line, using EndOfStream Property[^] to see if you've read the whole file.

it is bit simple using streamreader, see below snippet

C#
int counter = 0;
string line;

// Read the file and display it line by line.
System.IO.StreamReader file = 
   new System.IO.StreamReader("c:\\test.txt");
while((line = file.ReadLine()) != null)
{
   Console.WriteLine (line);
   //call your function here
   counter++;
}

file.Close();

// Suspend the screen.
Console.ReadLine();
