Question

我正在制作个人使用的应用程序，它将组织.png文件，并允许我通过应用程序（通过ListView）从目录远程删除它们。

我有一个片段会从ListView中删除该文件，但不会从实际的文件目录中删除。我希望能够在单击删除时同时执行这两项操作。

private void deleteToolStripMenuItem1_Click(object sender, EventArgs e)
    {
        if (MessageBox.Show("This will delete the file from the folder. Are you sure?", "Warning", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning) == DialogResult.Yes)
            for (int i = fileDisplayListView.SelectedItems.Count - 1; i >= 0; i--)
            {
                ListViewItem item = fileDisplayListView.SelectedItems[i];
                fileDisplayListView.Items[item.Index].Remove();
                File.Delete(fbd.SelectedPath + fileDisplayListView.Items.ToString());
            }
    }

其他代码段以获取更多信息..

private void openToolStripButton_Click(object sender, EventArgs e)
    {           
        fbd.ShowDialog();
        DirectoryInfo di = new DirectoryInfo(fbd.SelectedPath);
        directoryPath.Text = "Directory: " + fbd.SelectedPath;
        FileInfo[] Files =
            di.GetFiles("*.PNG*", SearchOption.AllDirectories);
        if (Files.Length == 0)
            MessageBox.Show("No .png files found in directory...", "Notification", MessageBoxButtons.OK, MessageBoxIcon.Question);
        fileDisplayListView.Items.Clear();
        foreach (FileInfo f in Files)
        {
            ListViewItem item = new ListViewItem(f.Name);             
           this.fileDisplayListView.Items.Add(f.Name);            
        }
        this.fileDisplayListView.View = View.Details;
        this.fileDisplayListView.Refresh();
    }

最后一部分File.Delete(fbd.SelectedPath + fileDisplayListView.Items.ToString());不起作用。请帮忙！

此代码获取目录中所有.jpg文件的列表，并将它们添加到ListView。按下按钮，它将删除所选的ListView元素和文件：

private FileInfo[] files;
public Form1()
{
    InitializeComponent();

    files = new DirectoryInfo(@"C:\Users\User\Pictures").GetFiles("*.jpg", SearchOption.AllDirectories);
    foreach (var file in files)
    {
        listView1.Items.Add(file.Name);
    }
}

private void button1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < listView1.SelectedItems.Count; i++)
    {
        var curentItem = listView1.SelectedItems[i];
        foreach (FileInfo file in files)
        {
            if (curentItem.Text == file.Name)
            {
                listView1.Items.Remove(curentItem);
                file.Delete();
                i--;
            }
        }
    }
}

This is the snippet I used to fix the application. It is a lot more directly related to how I am approaching the problem.

if (MessageBox.Show("This will delete the file from the folder. Are you sure?", "Warning", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning) == DialogResult.Yes)
            for (int i = fileDisplayListView.SelectedItems.Count - 1; i >= 0; i--)
            {
                ListViewItem item = fileDisplayListView.SelectedItems[i];
                string fpath = string.Empty;
                fileDisplayListView.Items[item.Index].Remove();
                fpath = fbd.SelectedPath.ToString() + "\\" + item.Text;
                File.Delete(fpath);
            }
