利用asp.net怎么將子文件夾綁定到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 綁定GridView 

/// <summary> 
/// 綁定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"));//獲得APPDIR文件夾下所有子文件夾名 

string[] FolderName = new string[FolderNames.Split(',').Length - 1];//聲明個數(shù)組為了保存文件夾絕對路徑 

FolderName = FolderNames.Split(',');//給文件夾絕對路徑數(shù)組賦值 

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);//截取文件夾名 

row["LKNAME"] = FolderName[i];//給 LKNAME 字符賦值 

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

dt.Rows.Add(row); 
} 

gvwGKWH.DataSource = dt;//綁定到數(shù)組 
gvwGKWH.DataBind(); 
}
