Windows Form: Copy file to another Folder (Directory) with OpenFileDialog and FolderBrowserDialog using C# and VB.Net

Hi nirmal90,

Add two Button controls and one OpenFileDialog and one FolderBrowserDialog in the page.

OpenFileDialog will be used to select file and FolderBrowserDialog will used to select the folder to save the file.

Then write the code in the Button click event.

Namespaces

C#

using System.IO;

VB.Net

Imports System.IO

Code

C#

private void btnBrowse_Click(object sender, EventArgs e)
{
    openFileDialog1.Multiselect = false;
    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        string fileName = Path.GetFileName(openFileDialog1.FileName);
        string filePath = openFileDialog1.FileName;
    }
}
private void btnSave_Click(object sender, EventArgs e)
{
    if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
    {
        string newFileName = Path.GetFileNameWithoutExtension(openFileDialog1.FileName) + ".cnc";
        File.Copy(openFileDialog1.FileName, Path.Combine(folderBrowserDialog1.SelectedPath, newFileName));
        MessageBox.Show("File Saved successfully.", "", MessageBoxButtons.OK);
    }
}

VB.Net

Private Sub btnBrowse_Click(sender As Object, e As EventArgs) Handles btnBrowse.Click
    openFileDialog1.Multiselect = False
    If openFileDialog1.ShowDialog() = DialogResult.OK Then
        Dim fileName As String = Path.GetFileName(openFileDialog1.FileName)
        Dim filePath As String = openFileDialog1.FileName
    End If
End Sub

Private Sub btnSave_Click(sender As Object, e As EventArgs) Handles btnSave.Click
    If folderBrowserDialog1.ShowDialog() = DialogResult.OK Then
        Dim newFileName As String = Path.GetFileNameWithoutExtension(openFileDialog1.FileName) & ".cnc"        
        File.Copy(openFileDialog1.FileName, Path.Combine(folderBrowserDialog1.SelectedPath, newFileName))
        MessageBox.Show("File Saved successfully.", "", MessageBoxButtons.OK)
    End If
End Sub
