Delete files through a button.

Guest User

Hello I need some help with deleting files .txt through a button with windows forms. Because when I try to do this, I'm getting this error when trying to delete.

Error is: file is being used in a process..... etc. So I can't delete the file.

Code is very simple: File.Delete(textBox1.Text);

Watched an tutorial and followed it, but it wont let me delete the files.

And I have this code too:

if(dlg.ShowDialog() == DialogResult.OK) {

StreamReader reader = new StreamReader(dlg.FileName, Encoding.Default);

textBox1.Text = dlg.FileName;

}

if this will help.

Could anyone help me?

Hey try this
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    StreamReader reader = new StreamReader(openFileDialog1.FileName, Encoding.Default);
    textBox2.Text = openFileDialog1.FileName;
    reader.Dispose();
    FileInfo fileInfo = new FileInfo(textBox2.Text);
    fileInfo.Delete();
}

You are using that file in StreamReader, just dispose/close that, like streamReader.Close();

"File is open check in task manager, so only your not able to delete file you suppose to close it before delete"

I have already checked task manager, but the file is not in task manager...
