Cannot write to file after reading

Question

In the following code I get the error \"stream was not writable\":

class Class1
{
    private static void Main()
    {
        FileStream fs = new F         


        

Answer 1

Dont close the first StreamWriter, it will close the underlying stream. And use using statements as Oscar suggests.

using (FileStream fs = new FileStream("C:\\temp\\fFile.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite))
{
    StreamReader r = new StreamReader(fs);
    string t = r.ReadLine();

    Console.WriteLine(t);

    StreamWriter w = new StreamWriter(fs);
    w.WriteLine("string");
    w.Close();
    r.Close();
    fs.Close();
}
