Reading a string line per line in C# [duplicate]

Answer 1

If you are reading it in from a file, it is easier to do just do:

foreach(var myString in File.ReadAllLines(pathToFile))
    interpret(myString);

If you are getting the string from somewhere else (a web service class or the like) it is simpler to just split the string:

foreach(var myString in entireString.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries))
    interpret(myString);

Answer 2

Check for null when you do a readLine - see the docs.

Answer 3

Like this:

string line;
while (null != (line = reader.ReadLine()) {
    Process(line);
}

Answer 4

I am not sure where you are reading from. If it is from the Console, you can check for the end of inputs string like "quit" to denote end of input

String input;
while((input = reader.readLine()) != "quit"){
   // do something
}

Answer 5

Dismissile is correct:

http://msdn.microsoft.com/en-us/library/system.io.streamreader.endofstream.aspx

while (!reader.EndOfStream) 
{ 
    string line = reader.ReadLine(); 
} 

Answer 6

The StreamReader class has an EndOfStream property. Have you looked into using that?
