How can I delete all data in a text file

yokzu

Hello,
I'm using the code below for writing text in a text file.

StreamWriter dosya = new StreamWriter("mac.txt");
dosya.WriteLine("first line");
dosya.WriteLine("second line");
dosya.Close();

But I couldnt be able to find, how can I delete all data in this text file?

An easy way to delete all the text from a text file without actually deleting the file itself is this:

System.IO.File.WriteAllText("mac.txt", "");

If you check the file length, it will now be zero.

Hi Sleepy..
i think that if you wanna delete all the Data in a text file and not deleting the file
you can do the following:

StreamWriter Sw=new StreamWriter("mac.text");
Sw.AutoFlush=true;
Sw.close();

hope this hepls :)

using(TextWriter txtw = new StreamWriter(finfo .Open(FileMode.Truncate)))
{
    txtw .Write("write my new text here");
}
