Return the pathname after saving file using saveFileDialog - C#

Question

I am creating and saving a csv file using saveFileDialog. I need to find a way to remember the pathName that the person saves the file to so that I can use the pathName to the file later on in the code.

The below code is what I have been trying, just to return the pathName but it will actually only be returning the sfd.FileName. Is there a way to get the full path?

 private void saveCSVbutton_Click(object sender, EventArgs e)
    {
        saveShipping();
        saveATT();
        saveVerizon();

        String shippingPath = saveShipping();
        MessageBox.Show(shippingPath);    
}  
private String saveShipping()
    {
        if (dataGridView1.Rows.Count > 0)
        {
            SaveFileDialog sfd = new SaveFileDialog();
            sfd.Filter = "CSV (*.csv)|*.csv";
            sfd.FileName = "shippingOutput.csv";
            bool fileError = false;
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                if (File.Exists(sfd.FileName)) 
                {
                    try
                    {//overwrite file
                        File.Delete(sfd.FileName);
                    }
                    catch (IOException ex)
                    {
                        fileError = true;
                        MessageBox.Show("It wasn't possible to write the data to the disk." + ex.Message);
                    }
                }
                if (!fileError)
                {
                    try
                    {
                        int columnCount = dataGridView1.Columns.Count;
                        string columnNames = "";
                        string[] outputCsv = new string[dataGridView1.Rows.Count + 1];
                        for (int i = 0; i < columnCount; i++)
                        {
                            columnNames += dataGridView1.Columns[i].HeaderText.ToString() + ",";
                        }
                        outputCsv[0] += columnNames;

                        for (int i = 1; i < dataGridView1.Rows.Count; i++)
                        {
                            for (int j = 0; j < columnCount; j++)
                            {
                                outputCsv[i] += dataGridView1.Rows[i - 1].Cells[j].Value.ToString() + ",";
                            }
                        }

                        File.WriteAllLines(sfd.FileName, outputCsv, Encoding.UTF8);
                        MessageBox.Show("Data Exported Successfully", "Info");
                        String attachPathName = sfd.FileName;
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show("Error :" + ex.Message);
                    }
                }
            }
        }
        else
        {
            MessageBox.Show("No Record To Export", "Info");
        }
        return attachPathName;
    }

You can use Path.GetDirectoryName(sfd.FileName) to get full path to the file
