During winform development, the open file dialog box (openfiledialog) and folder browse dialog box (folderbrowserdialog) are often used ).

1. Folder browsing dialog box (folderbrowserdialog)

Step 1: Introduce a folderbrowserdialog component from the toolbox. When this component is added to the form, it will appear in a blank area below the form,

Private void btnselectpath_click (Object sender, eventargs e) {folderbrowserdialog1.description = "select folder"; folderbrowserdialog1.shownewfolderbutton = true; folderbrowserdialog1.rootfolder = environment. specialfolder. desktop; dialogresult result = folderbrowserdialog1.showdialog (); If (result = dialogresult. OK) {txtmaindir. TEXT = folderbrowserdialog1.selectedpath ;}}

 

2. open the file dialog box (openfiledialog)

private void btnSelectFile_Click(object sender, EventArgs e){    openFileDialog1.Filter = "Special Files(*.xls)|*.xls|All files (*.*)|*.*";    DialogResult result = openFileDialog1.ShowDialog();    if (result == DialogResult.OK)    {        txtFile.Text = openFileDialog1.FileName;    }}
