Get directory in C#

Hi everyone

Is my first time trying to get the specific path of a directory please, Why  I can not get the path of this program into my listview?

       
        void MainFormLoad(object sender, EventArgs e)
        {
                listView1.View = View.Details;
                listView1.GridLines = true;
                listView1.FullRowSelect = true;
                listView1.Columns.Add("Directory list:");
                
                
        }
        
        void Button1Click(object sender, EventArgs e)
        {
            
                string[] Path = Directory.GetFiles(@"C:\Windows\Microsoft.NET\",".dll",SearchOption.AllDirectories);
                
                
                foreach (var list in Path){
                var items = listView1.Items;
                items.Add(list);
                
                
               
                
                
            }
                
                            
            
        }
    }
}
