Question

I have some code in static void main, although I would like it to call the startremdup method (as it calls the RemoveDuplicate, with the appropriate parameters) from static void main, I have tried startremdup();

private void RemoveDuplicate(string sourceFilePath, string destinationFilePath)
{
    var readLines = File.ReadAllLines(sourceFilePath, Encoding.Default);

    File.WriteAllLines(destinationFilePath, readLines.Distinct().ToArray(), Encoding.Default);
}


private void startremdup(object sender, EventArgs e)
{
    RemoveDuplicate("C:\test.txt", "C:\test2.txt");
}

Answer 1

Make both startremdup() and RemoveDuplicate() static.

private static void RemoveDuplicate(string sourceFilePath, string destinationFilePath)
{
    var readLines = File.ReadAllLines(sourceFilePath, Encoding.Default);

    File.WriteAllLines(destinationFilePath, readLines.Distinct().ToArray(), Encoding.Default);
}


private static void startremdup(object sender, EventArgs e)
{
    RemoveDuplicate("C:\test.txt", "C:\test2.txt");
}
