Web 窗体设计器生成的代码
private void loadNodes(TreeNode currentNode, string path)
{
DirectoryInfo mainDir = new DirectoryInfo(path);
try
{
//遍历文件目录
foreach(DirectoryInfo d in mainDir.GetDirectories())
{
TreeNode t = new TreeNode();
t.Text = d.Name;
t.ImageUrl="webctrl_client\\1_0\\images\\folder.gif";
currentNode.Nodes.Add(t);
//遍历文件
foreach(FileInfo f in mainDir.GetFiles())
{
//增加文件
TreeNode file = new TreeNode();
file.Text = f.Name;
file.ImageUrl="file.gif";
t.Nodes.Add(file);
}
//递归调用
loadNodes(t, path + "/" + d.Name);
}
}
catch(Exception Ex)
{
this.lbMessage.Text = Ex.Message;
}
}
}
}
查找不现类型的文件可以调用方法 GetFiles("*.text");
就会查询以text为后缀的文件。
