下面的代码显示了folderBrowser
控件正在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,我想打开正在单击的文件。我使用LISTVIEW_itemactivation
编写了有用的代码问题是我无法打开正在选择的文件,我做错了。
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()); }
}
答案 0 :(得分:0)
好吧,根据你如何填充列表,这个修改过的代码应该可以工作。
private void listView1_ItemActivate(object sender, EventArgs e)
{
try
{
string sPath = listView1.SelectedItem.SubItems[0].Text;
Process.Start(sPath);
}
catch(Exception Exc)
{
MessageBox.Show(Exc.ToString());
}
}
但是你还需要摆脱这条线,因为你 从不 能够在不知道它的扩展名的情况下加载文件。
string fileName = Path.GetFileNameWithoutExtension(file);
请参阅,当您加载ListViewItem
时,它正在加载该数组的所有SubItems
。此外,Directory.GetFiles(folderBrowser.SelectedPath);
返回的数组返回一个文件数组,其中包含完整路径,因此,如果您选择了第一个SubItem
,那将是该文件的完整路径,从而发出{该文件路径上的{1}}将导致shell在其默认程序中打开该文件。
