C# 读取文件夹名添加项目

 //读取文件夹名
        string path = @"C:\measure";
        private void path_name()
        {
            DirectoryInfo root = new DirectoryInfo(path);
            DirectoryInfo[] dics=root.GetDirectories();
            foreach (var name in dics)
            cmb_selection.Items.Add(name);    //添加到Combobox
        }

将C盘measure文件下的文件名添加到cmb_selection列表里面。

 private void cmb_select(object sender, EventArgs e)
        {

            selection = cmb_selection.Text;
          //初始化
            cmb_selection.Enabled = false;
            groupBox3.Enabled = true;
            menuStrip1.Enabled = true;
        }


       //选择文件名

string selection =null;
        public string fileInit()
        {
            string filename = @"C:\measure\" + selection;
            return filename;
        }

  circle_str = File.ReadAllLines(fileInit() + @"\circle\circle" + (i + 1).ToString() + ".txt");

保存到不同的文件夹中。
