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());    }    
}

好吧,根据您填充列表的方式,这个修改后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());
    }
}

但是您还需要摆脱这一行,因为您永远无法在不知道它的扩展名的情况下加载文件。

string fileName = Path.GetFileNameWithoutExtension(file);

看,当您ListViewItem像您一样加载时,它正在加载SubItems该数组的所有内容。此外,Directory.GetFiles(folderBrowser.SelectedPath);返回的数组返回一个包含完整路径的文件数组,因此,如果您选择第一个SubItem将成为该文件的完整路径的文件,因此Process.Start在该文件路径上发出将导致 shell 打开文件在其默认程序中。
