VS C# 2005編程 ,從Directory members開始

        本文假設讀者已有一定的編程基礎。
        要對目錄進行操作，須在程序中using System.IO,否則編譯無法通過。
        程序界面如下：

                             

        要創建一個新目錄，在Dir Path文字框內輸入目錄路徑和名稱（如上圖紅字處），然後按New Dir按鈕，代碼如下：

private void NewButton_Click(object sender, EventArgs e)
       {
            try
            {
                if (Directory.Exists(dirtext.Text))
                {
                    MessageBox.Show("The Directory is exists.");
                }
                else
                {
                    Directory.CreateDirectory(dirtext.Text);
                    MessageBox.Show("Create New Directory successfully");
                }
            }
            catch
            {
                MessageBox.Show("Create Directory failed");
            }
        }

        同樣，刪除目錄代碼如下：

private void DelButton_Click(object sender, EventArgs e)
        {
            if (!Directory.Exists(dirtext.Text))
            {
                MessageBox.Show("The Directory not exists");
                return;
            }
            else
            {
                try
                {
                    Directory.Delete(dirtext.Text);
                    MessageBox.Show("Successfully");
                }
                catch
                {
                    MessageBox.Show("Failed");
                }
            }
        }
