For File browser you need two thing
1. Directory path (Directory which user selects)
2. List of all file.
for 1. Requirement you can use FileBrowser,
and for 2.
you have to add list box and load all file list in the below code will help
string[] filePaths = Directory.GetFiles(@"c:\user\public\picture");
foreach (string m in filePaths)
{
ListViewItem liv = new ListViewItem(m);
listView1.Items.Add(liv);
}
All the Best
