asp.net 获取目录下的文件数和文件夹数_实用技巧

分享到:

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:\\","*");
for(int i=0; i <Files.Length; i )
{
Response.Write(Files " <br/>");
}
Response.Write("统计文件:" Files.Length "个 <br/>--------- <br>");
