Write to File in C#
Used to write to a file.
Syntax
///declare an array of strings first, each array element being a file line
string[] fileLines = { }; ///lines in here
File.WriteAllLines("filename", fileLines);
Notes
The File class is within the System.IO namespace.
A StreamWriter can be used to write one line at a time and call the WriteLine() method.
Example
string[] grades = {"Student 1: 85", "Student 2: 60", "Student 3: 75"};
File.WriteAllLines("grades.txt", grades);
