静态生成要在虚拟目录下创建文件夹 来保存生成的页面 那么就要对文件进行操作 一、创建文件夹
using System.IO; string name = "aa";
string path = Server.MapPath("") + "\\" + name;
if (Directory.Exists(path))
{
Response.Write("<script>alert('文件夹已存在了!');history.go(-1);</script>");
}
else
{
DirectoryInfo folder=Directory.CreateDirectory(path);
string time = Convert.ToString(Directory.GetCreationTime(path));
string foldername = name.Substring(name.LastIndexOf("\\") + 1);
Response.Write("添加成功!");
Response.Write("添加时间："+time);
Response.Write("文件夹名："+foldername);
} 二、删除文件夹 using System.IO;
string name = "aa";
string path = Server.MapPath("") + "\\" + name;
if (Directory.Exists(path))
{
Directory.Delete(path);
Response.Write("删除成功!");
}
else
{
Response.Write("<script>alert('文件夹不存在!');history.go(-1);</script>");
} 三、文件夹的移动 string name1 = "aa";
string name2 = "bb\\aa";
//移动到的文件夹里,把AA移动到BB里
string path1 = Server.MapPath("") + "\\" + name1;
string path2 = Server.MapPath("") + "\\" + name2;
if (!Directory.Exists(path1))
{
Response.Write("<script>alert('文件夹"+name1+"不存在!');history.go(-1);</script>");
return;
}
if (Directory.Exists(path2))
{
Response.Write("<script>alert('文件夹" + name2 + "已存在!');history.go(-1);</script>");
return;
}
try
{
Directory.Move(path1, path2);
Response.Write("文件夹移动成功!");
}
catch
{
Response.Write("<script>alert('必须在同一目录下操作!');history.go(-1);</script>");
} 四、获取文件夹下的文件列表 前台
<asp:ListBox ID="list" runat="server" Width="200px" Height="300px" Visible="false"></asp:ListBox>
后台
string name = "aa";
string path = Server.MapPath("") + "\\" + name;
if (!Directory.Exists(path))
{
list.Visible = false;
Response.Write("<script>alert('文件夹" + name + "不存在!');history.go(-1);</script>");
return;
}
else
{
DirectoryInfo foldinfo = new DirectoryInfo(path);
FileSystemInfo[] dirs = foldinfo.GetFileSystemInfos();
if (dirs.Length < 1)
{
Response.Write("<script>alert('文件夹中没数据!');history.go(-1);</script>");
return;
}
list.Visible = true;
list.DataSource = dirs;
list.DataBind();
} 五、创建文件
string name = "aa.aspx";
string path = Server.MapPath("") + "\\" + name;
if (File.Exists(path))
{
Response.Write("<script>alert('文件" + name + "已存在!');history.go(-1);</script>");
return;
}
else
{
FileStream fs = File.Create(path); fs.Close();
Response.Write("文件" + name + "添加成功!");
}
六、拷贝文件
string name1 = "aa\\1.html";
string name2 = "bb\\1.html";
string path1 = Server.MapPath("") + "\\" + name1;
string path2 = Server.MapPath("") + "\\" + name2;
if (!File.Exists(path1))
{
Response.Write("<script>alert('文件" + name1 + "不存在!');history.go(-1);</script>");
return;
}
if (File.Exists(path2))
{
Response.Write("<script>alert('文件" + name2 + "已存在!');history.go(-1);</script>");
return;
}
try
{
File.Copy(path1, path2);
Response.Write("拷贝成功!");
}
catch
{
Response.Write("拷贝失败!");
} 七、移动文件
string name1 = "aa\\1.html";
string name2 = "bb\\1.html";
string path1 = Server.MapPath("") + "\\" + name1;
string path2 = Server.MapPath("") + "\\" + name2;
if (!File.Exists(path1))
{
Response.Write("<script>alert('文件" + name1 + "不存在!');history.go(-1);</script>");
return;
}
if (File.Exists(path2))
{
Response.Write("<script>alert('文件" + name2 + "已存在!');history.go(-1);</script>");
return;
}
try
{
File.Move(path1, path2);
Response.Write("移动成功!");
}
catch
{
Response.Write("移动失败!");
} 八、文件删除
string name = "bb\\1.html";
string path = Server.MapPath("") + "\\" + name; if (!File.Exists(path))
{
Response.Write("<script>alert('文件" + name + "不存在!');history.go(-1);</script>");
return;
}
try
{
File.Delete(path);
Response.Write("删除成功!");
}
catch
{
Response.Write("删除失败!");
} 九、获取文件的详细信息
string name = "aa\\11.txt";
string path = Server.MapPath("") + "\\" + name;
if (!File.Exists(path))
{
Response.Write("<script>alert('文件" + name + "不存在!');history.go(-1);</script>");
return;
}
else
{
FileInfo file = new FileInfo(path);
string filexinxi1, filexinxi2, filexinxi3, filexinxi4, filexinxi5;
//文件路径
filexinxi1 = file.FullName;
//文件大小,字节
filexinxi2 = file.Length+"字节";
//文件属性
filexinxi3 = file.Attributes.ToString();
//文件创建时间
filexinxi4 = file.CreationTime.ToShortDateString();
//文件上次访问时间
filexinxi5 = file.LastAccessTime.ToShortDateString();
Response.Write("文件路径:"+filexinxi1+"<br>");
Response.Write("文件大小:" + filexinxi2 + "<br>");
Response.Write("文件属性:" + filexinxi3 + "<br>");
Response.Write("文件创建时间:" + filexinxi4 + "<br>");
Response.Write("文件上次访问时间:" + filexinxi5 + "<br>");
}
十、读取文件内容 string name = "aa\\11.html";
string path = Server.MapPath("") + "\\" + name;
FileInfo fi = new FileInfo(path);
//获取文件名
string filename = fi.Name;
//获取文件扩展名
string extension = fi.Extension;
//判断该文件是否为txt格式
if (extension != ".html")
{
Response.Write("<script>alert('请选择html格式文件!');history.go(-1);</script>");
return;
}
StreamReader sr = new StreamReader(path, System.Text.Encoding.Default);
Response.Write("文件中的内容如下:<br>");
Response.Write(sr.ReadToEnd());
sr.Close();
十一、文件的写入
string name = "aa\\11.html";
string content1="<html><title>大家好</title></html>";
string path = Server.MapPath("") + "\\" + name;
FileInfo fi = new FileInfo(path);
//获取文件名
string filename = fi.Name;
//获取文件扩展名
string extension = fi.Extension;
//判断该文件是否为txt格式
if (extension != ".html")
{
Response.Write("<script>alert('请选择html格式文件!');history.go(-1);</script>");
return;
}
StreamWriter sr = new StreamWriter(path, true, System.Text.Encoding.GetEncoding("gb2312"));
sr.WriteLine(content1);
sr.Close();
Response.Write("文件写入成功!");
