我下面的代码显示了由folderBrowser
控件选择的文件夹的列表视图。在列表视图中显示文件夹和文件后,我想打开单击的文件。我已经使用LISTVIEW_itemactivation
. 问题是我无法打开选定的文件。我究竟做错了什么?
private void PopulateListView()
{
listView1.Clear();
//headers listview
listView1.Columns.Add("File Name", 150);
listView1.Columns.Add("Last Accessed", 110);
listView1.Columns.Add("Size", 100);
//listView1.ItemActivate += new System.EventHandler(listView1_ItemActivate);
if (folderBrowser.ShowDialog() == DialogResult.OK)
{
string[] files = Directory.GetFiles(folderBrowser.SelectedPath);
string[] folders = Directory.GetDirectories(folderBrowser.SelectedPath);
foreach (string file in files)
{
long folderSize = 0;
string fileName = Path.GetFileNameWithoutExtension(file);
FileInfo finfo = new FileInfo(file);
folderSize += finfo.Length;
ListViewItem item = new ListViewItem(new[] { fileName, File.GetLastAccessTime(file).ToString(), finfo.Length.ToString() });
images();
item.ImageIndex = 1;
listView1.Items.Add(item);
}
foreach (string file in folders)
{
string fileName = Path.GetFileNameWithoutExtension(file);
ListViewItem item = new ListViewItem(new[] { fileName, File.GetLastAccessTime(file).ToString(), file.Length.ToString() });
images();
item.ImageIndex = 0;
listView1.Items.Add(item);
}
}
}
private void button1_Click(object sender, EventArgs e)
{
PopulateListView();
textBox1.Text = folderBrowser.SelectedPath;
}
private void images(){
try
{
imageList1.Images.Add(Bitmap.FromFile("./images/file.gif"));
imageList1.Images.Add(Bitmap.FromFile("./images/Folder.gif"));
}
catch (FileNotFoundException) { }
}
private void listView1_DoubleClick(object sender, EventArgs e)
{
ListViewItem item_clicked = listView1.SelectedItems[0];
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
listView1.View = View.LargeIcon;
}
private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
listView1.View = View.SmallIcon;
}
private void radioButton3_CheckedChanged(object sender, EventArgs e)
{
listView1.View = View.Details;
}
private void radioButton4_CheckedChanged(object sender, EventArgs e)
{
listView1.View = View.List;
}
private void radioButton5_CheckedChanged(object sender, EventArgs e)
{
listView1.View = View.Tile;
}
private void listView1_ItemActivate(object sender, EventArgs e)
{
try
{
string sPath = listView1.SelectedItems.ToString();
string sFileName = listView1.FocusedItem.Text;
Process.Start(sPath + "\\" + sFileName);
}
catch(Exception Exc) { MessageBox.Show(Exc.ToString()); }
