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;
}
