 第一章：C#文件夹与文件、磁盘的处理技巧

（1）使用DriveInfo类取得计算机磁盘信息

//使用DriveInfo类的首要操作就是调用其GetDrives方法取得目前系统中所有逻辑磁盘驱动器的DriveInfo类型

private void button1_Click(object sender, EventArgs e)
        {
           StringBuilder sb = new StringBuilder();//可变字符串
           DriveInfo[] myAllDrives = DriveInfo.GetDrives();
           try
           {
                foreach (DriveInfo myDrive in myAllDrives)
                {
                    if (myDrive.IsReady)
                    {
                      sb.Append("磁盘驱动器符：");
                      sb.AppendLine(myDrive.Name);
                      sb.Append("磁盘卷符：");
                      sb.AppendLine(myDrive.VolumeLabel);
                      sb.Append("磁盘类型：");
                      sb.AppendLine(myDrive.DriveType.ToString());
                        sb.Append("磁盘的大小：");
                        sb.AppendLine(myDrive.TotalSize.ToString());
                        sb.Append("磁盘剩余空间：");
                        sb.AppendLine(myDrive.TotalFreeSpace.ToString());
                        sb.Append("总剩余空间（含磁盘配额）：");
                   sb.AppendLin(myDrive.AvailableFreeSpace.ToString());
                        sb.AppendLine("------------------");
                    }
                }
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            frmStatusMessage.Close();
            this.richTextBox1.Text = sb.ToString();
           //显示于DataGridView控件中
            DriveInfo.GetDrives();
        }
