How can I load a folders files into a ListView?
提问by Sergio Tapia
I'd like to have a user select a folder with the FolderBrowserDialog and have the files loaded into the ListView.
我想让用户使用 FolderBrowserDialog 选择一个文件夹，并将文件加载到 ListView 中。
My intention is to make a little playlist of sorts so I have to modify a couple of properties of the ListView control I'm assuming. What properties should I set on the control?
我的目的是制作一个小播放列表，所以我必须修改我假设的 ListView 控件的几个属性。我应该在控件上设置哪些属性？

Surely you just need to do the following:
当然，您只需要执行以下操作：
FolderBrowserDialog folderPicker = new FolderBrowserDialog();
if (folderPicker.ShowDialog() == DialogResult.OK)
{
ListView1.Items.Clear();
string[] files = Directory.GetFiles(folderPicker.SelectedPath);
foreach (string file in files)
{
string fileName = Path.GetFileNameWithoutExtension(file);
ListViewItem item = new ListViewItem(fileName);
item.Tag = file;
ListView1.Items.Add(item);
}
}
Then to get the file out again, do the following on a button press or another event:
然后要再次取出文件，请在按下按钮或其他事件时执行以下操作：
if (ListView1.SelectedItems.Count > 0)
{
ListViewItem selected = ListView1.SelectedItems[0];
string selectedFilePath = selected.Tag.ToString();
PlayYourFile(selectedFilePath);
}
else
{
// Show a message
}
For best viewing, set your ListView to Details Mode:
为了获得最佳查看效果，请将您的 ListView 设置为详细信息模式：
ListView1.View = View.Details;

A basic function could look like this:
一个基本函数可能如下所示：
public void DisplayFolder ( string folderPath )
{
string[ ] files = System.IO.Directory.GetFiles( folderPath );
for ( int x = 0 ; x < files.Length ; x++ )
{
lvFiles.Items.Add( files[x]);
}
}

List item
项目清单
private void buttonOK_Click_1(object sender, EventArgs e)
私有无效按钮OK_Click_1（对象发送者，EventArgs e）
{
DirectoryInfo FileNm = new DirectoryInfo(Application.StartupPath);
var filename = FileNm.GetFiles("CONFIG_*.csv");
//Filename CONFIG_123.csv,CONFIG_abc.csv,etc
//文件名CONFIG_123.csv、CONFIG_abc.csv等
foreach(FileInfo f in filename)
listViewFileNames.Items.Add(f.ToString());
}
