利用asp.net怎么将子文件夹绑定到gridview中

Helper app_Helper = new Helper(); 

DataSet ds = new DataSet(); 

DataTable dt = new DataTable(); 

protected void Page_Load(object sender, EventArgs e) 
{ 
gvwBind(); 
} 

#region 绑定GridView 

/// <summary> 
/// 绑定GridView 
/// </summary> 
protected void gvwBind() 
{ 
INI.INIPath iniINIPath = new INI.INIPath(); 
INI.INIFile iniINIFile = new INI.INIFile(iniINIPath.getINIPath()); 

string FolderNames = app_Helper.GetAllFolder(Server.MapPath("../../APPDIR"));//获得APPDIR文件夹下所有子文件夹名 

string[] FolderName = new string[FolderNames.Split(',').Length - 1];//声明个数组为了保存文件夹绝对路径 

FolderName = FolderNames.Split(',');//给文件夹绝对路径数组赋值 

dt.Columns.Add("LKNAME", typeof(string)); 
dt.Columns.Add("qdjsjm", typeof(string)); 
dt.Columns.Add("qdipdz", typeof(string)); 

for (int i = 0; i < FolderName.Length - 1; i++) 
{ 
DataRow row = dt.NewRow(); 

FolderName[i] = FolderName[i].Substring(FolderName[i].LastIndexOf('\\') + 1);//截取文件夹名 

row["LKNAME"] = FolderName[i];//给 LKNAME 字符赋值 

if (!iniINIFile.IniReadValue("dzjclkzp", FolderName[i]).Equals(""))//配置文件中是否存在相同文件夹名的key 
{ 
row["qdjsjm"] = iniINIFile.IniReadValue("dzjclkzp", FolderName[i]).Split(',')[0];//给qdjsjm字段赋值 
row["qdipdz"] = iniINIFile.IniReadValue("dzjclkzp", FolderName[i]).Split(',')[1];//给qdipdz字段赋值 
} 

dt.Rows.Add(row); 
} 

gvwGKWH.DataSource = dt;//绑定到数组 
gvwGKWH.DataBind(); 
} 

#endregion 绑定GridView
