How best to read a File into List

Question

I am using a list to limit the file size since the target is limited in disk and ram. This is what I am doing now but is there a more efficient way?

readonly         


        

Answer 1

//this is only good in .NET 4
//read your file:
List ReadFile = File.ReadAllLines(@"C:\TEMP\FILE.TXT").ToList();

//manipulate data here
foreach(string line in ReadFile)
{
    //do something here
}

//write back to your file:
File.WriteAllLines(@"C:\TEMP\FILE2.TXT", ReadFile);
