复制代码 代码如下:
int j = 0;
protected void button1_click(object sender, eventargs e)
{
directoryinfo dir = new directoryinfo(textbox1.text.tostring());
label1.text = getallfiles(dir).tostring();
}getallfiles方法为自定义方法，实现遍历整个文件夹文件的方法。代码如下：
public int getallfiles(directoryinfo dir)
{
filesysteminfo[] fileinfo = dir.getfilesysteminfos();
foreach (filesysteminfo i in fileinfo)
{
if (i is directoryinfo)
{
getallfiles((directoryinfo)i);
}
else
{
j++;
}
}
return j;
}

string[] directorys = system.io.directory.getdirectories("d:\\","*");
for(int i=0; i <directorys.length; i )
{
response.write(directorys " <br/>");
}
response.write("统计目录：" directorys.length "个 <br/>--------- <br>");

string[] files = system.io.directory.getfiles("d:\\","*");
