Question

我正在尝试从C＃中的打开文件对话框中选择目录，但是当我实际将项目添加到列表视图时，它没有显示。到目前为止，这是我的代码......我错过了什么？

private void btnChoose_Click(object sender, EventArgs e)
    {
        try
        {
            FolderBrowserDialog folderPicker = new FolderBrowserDialog();
            listLeft.View = View.Details;
            if (folderPicker.ShowDialog() == DialogResult.OK)
            {
                DirectoryInfo di = new DirectoryInfo(folderPicker.SelectedPath);
                FileInfo[] files = di.GetFiles();
                DirectoryInfo[] directories = di.GetDirectories();

                foreach (DirectoryInfo directory in directories)
                {
                    listLeft.Items.Add("Directory " + directory.Name);
                }
                foreach (FileInfo file in files)
                {
                    listLeft.Items.Add(file.Name);
                }
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("An error occurred: " + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

我假设listLeft是你的ListView。你需要添加这样的子项：

            foreach (DirectoryInfo directory in directories)
            {
                ListViewItem lvi = new ListViewItem();
                lvi.SubItems.Add("Directory " + directory.Name);
                listLeft.Items.Add(lvi);
            }
            foreach (FileInfo file in files)
            {
                ListViewItem lvi = new ListViewItem();
                lvi.SubItems.Add(file.Name);
                listLeft.Items.Add(lvi);
            }

编辑：试试这个：

private void button1_Click(object sender, EventArgs e)
{
    try
    {
        listLeft.Columns.Add(new ColumnHeader());
        FolderBrowserDialog folderPicker = new FolderBrowserDialog();
        listLeft.View = View.Details;
        if (folderPicker.ShowDialog() == DialogResult.OK)
        {
            DirectoryInfo di = new DirectoryInfo(folderPicker.SelectedPath);
            FileInfo[] files = di.GetFiles();
            DirectoryInfo[] directories = di.GetDirectories();

            foreach (DirectoryInfo directory in directories)
            {
                listLeft.Items.Add("Directory " + directory.Name);
            }
            foreach (FileInfo file in files)
            {
                listLeft.Items.Add(file.Name);
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show("An error occurred: " + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

它应该添加到列表框中 - 如果目录和文件对象中有对象...尝试在每个方法中设置断点并查看发生的情况。如果没有触发断点，则Get（）方法出现问题......

Answer 3

你的问题陈述了'winforms'中的列表视图。

但是System.Windows.Forms.ListBox没有View属性，所以你的代码行

listLeft.View = View.Details;

当我尝试重现时，

无法编译。

您是指代WPF列表框吗？在这种情况下，您能告诉我们更多代码，特别是您的数据绑定吗？
