ASP.NET静态页面的绝对路径转相对路径
经常有新手在做页面的时候不注意路径的安排，通常图方便都写成绝对路径。结果在编辑的时候（非dreamware下）发现不能直接点开，非要经过服务器才可以看到效果。
于是写了一段代码，直接将这些有规律的绝对链接转为相对链接，代码如下：
程序代码
using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
namespace FilePathTool
{
class FilePath
{
//文件的根目录
static readonly string RootLocal = @"F:workfolderproject";
List<FileItem> files = new List<FileItem>();
public FilePath()
{
DirectoryInfo root = new DirectoryInfo(RootLocal);
GetFolders(root, 0,"");
DealFile();
Console.WriteLine(files.Count);
Console.Read();
}
/// <summary>
/// 得到文件夹
/// </summary>
void GetFolders(DirectoryInfo root, int Level, string path)
{
foreach (DirectoryInfo item in root.GetDirectories())
{
GetFolders(item, Level + 1, path + item.Name + "/");
}
//得到文件
foreach (FileInfo item in root.GetFiles())
{
files.Add(new FileItem {
Level = Level,
Name = item.Name,
Extension = item.Extension,
Path = item.FullName,
AbsolutePath = path
});
}
}
/// <summary>
/// 处理已得到的文件
/// </summary>
void DealFile()
{
foreach (FileItem item in files)
{
if (item.Extension == ".htm")
{
Console.WriteLine(item.AbsolutePath);
DealRepalce(item);
}
}
}
/// <summary>
/// 替换方法
/// </summary>
void DealRepalce(FileItem item)
{
FileInfo file = new FileInfo(item.Path);
string txt = File.ReadAllText(item.Path, Encoding.Default);
txt = RepalceProcess(txt, item);
Console.WriteLine(txt);
//Console.Read();
File.WriteAllText(item.Path, txt, Encoding.Default);
}
/// <summary>
/// 遍历替换
/// </summary>
string RepalceProcess(string txt, FileItem model)
{
foreach (FileItem item in files)
{
string relativePath = item.AbsolutePath + item.Name;
if (txt.Contains(relativePath))
{
txt = RepalceSingle(txt, relativePath, item, model);
}
}
return txt;
}
/// <summary>
/// 替换
/// </summary>
string RepalceSingle(string txt, string relativePath, FileItem item, FileItem model)
{
//当文件在同一目录下只不需要显示路径
if (item.AbsolutePath == model.AbsolutePath)
{
return txt.Replace("/" + relativePath, item.Name);
}
else
{
return txt.Replace("/" + relativePath, GetDeep(model.Level) + relativePath);
}
}
static string tempDeep = @"../";
/// <summary>
/// 按文件深度得到父路径
/// </summary>
/// <param name="Level"></param>
/// <returns></returns>
string GetDeep(int Level)
{
string deep = "";
for (int i = 0; i < Level; i++)
{
deep += tempDeep;
}
return deep;
}
}
/// <summary>
/// 文件信息实体
/// </summary>
public class FileItem
{
public int Level
{
get;
set;
}
public string Name
{
get;
set;
}
public string Extension
{
get;
set;
}
public string Path
{
get;
set;
}
public string AbsolutePath
{
get;
set;
}
}
}
