ファイルマネージャーをUserControlで作成すると再利用できるのではないかと思い試作してみました。

MessageBox.Show(ee.FullPath,"ファイルが選択されたよ。");
};
var cms = new ContextMenuStrip();
var viewLabel = new ToolStripMenuItem{ Text = "パスを表示" };
var deleteLabel = new ToolStripMenuItem{ Text = "削除" };
cms.Items.AddRange(new ToolStripMenuItem[]{viewLabel, deleteLabel});
fm.ContextMenuStrip = cms;
viewLabel.Click += (s, e) =>
{
string text = "";
foreach(var t in fm.GetSlectedPath())
{
text = text + t + "\n";
}
MessageBox.Show(text, "パスの表示");
};
deleteLabel.Click += (s, e) =>
{
string text = "";
foreach(var t in fm.GetSlectedPath())
{
text = text + t + "\n";
}
var result = MessageBox.Show(text, "削除しますか？", MessageBoxButtons.YesNo, MessageBoxIcon.Hand);
if (result != DialogResult.Yes) return;
foreach(var path in fm.GetSlectedPath())
{

}
fm.Reload();
};
