响应式布局实现步骤题外话这两天公司要做一个静态页面展示的优化，主要是要能够被集成在别的项目页面内，本来以为只是一个简单的html页面展示，没想到最后越做越复杂，就顺势把所有代码做了一次整理，领导要求支持尺寸最小为800px，我想了想，要不直接给干到300px好了因为领导总说要大胆创新，要敢想敢做，之前工作中的自己太束手束脚，这回也潇洒一把，三天时间，从对响应式一点不知，到现在自己设计页面，自己布局，做出来可以支持阅读详情

TreeNode tn;
foreach(string di in Directory.GetDirectories(@"c:\"))
{
tn=new TreeNode();
tn.Text=di;
treeView1.Nodes.Add(tn);
}
foreach(string di in Directory.GetFiles(@"c:\"))
{
tn=new TreeNode();
tn.Text=di;
treeView1.Nodes.Add(tn);
}

谢谢，我的意思是将C：盘下所有的文件夹和文件，包括文件夹的子文件夹、文件，子文件夹下的子文件夹、文件.....就是一次加入所有的文件夹和文件。

Directory.GetFiles("c:\\");
Directory.GetDirectories("c:\\");
一个是得到C盘根目录下的所有文件
一个是得到所有根目录下的所有文件夹
你把这些添加到treeview中去。
