(一). 功能

         操作配置文件[*.ini]類

(二). 代碼

     1. 核心類文件 inifile.cs 代碼

 1 /// <summary>
 2 /// inifile 操作類
 3 /// </summary>
 4 public class inifile
 5 {
 6     [dllimport("kernel32")]
 7     private static extern long writeprivateprofilestring(string section,string key,string val,string filepath);
 8 
 9     [dllimport("kernel32")]
10     private static extern int getprivateprofilestring(string section,string key,string def, stringbuilder retval,int size,string filepath);
11
12     //要訪問的文件路徑
13     private string strfilepath;
14
15     public string filepath
16     {
17       get { return strfilepath; }
18       set { strfilepath = value; }
19     }
20
21     public inifile()
22     {    
23     }
24     
25     public inifile( string strfilepath )
26     {   
27         this.strfilepath = strfilepath;
28     }    
29
30     public void writevalue(string strsection,string strkey,string strvalue)
31     {
32         if (filepath.length == 0)
33         {
34             throw new exception("沒有設置路徑");
35         }
36         writeprivateprofilestring(strsection, strkey, strvalue, this.filepath);       
37     }
38      
39     public string readvalue(string strsection,string strkey)
40     {
41         if (filepath.length == 0)
42         {
43             throw new exception("沒有設置路徑");
44         }
45         stringbuilder sb = new stringbuilder();
46         int i = getprivateprofilestring(strsection, strkey, "", sb, 255, this.filepath);
47         return sb.tostring();
48     }
49 }
2. 后臺調用文件 inifile.aspx.cs 代碼

 1 protected void page_load(object sender, eventargs e)
 2     {
 3         //read
 4         inifile ini = new inifile();
 5         ini.filepath = request.physicalapplicationpath + "ini.ini";
 6         string strreturnvalue = ini.readvalue("annabelle", "time");
 7         response.write(strreturnvalue);
 8
 9         //write
10         inifile ini = new inifile();
11         ini.filepath = request.physicalapplicationpath + "ini.ini";       
12         string strreturnvalue = ini.readvalue("annabelle", "time");
13         response.write(strreturnvalue);
14         ini.writevalue("annabelle", "time", "0");
15         strreturnvalue = ini.readvalue("annabelle", "time");
16         response.write(strreturnvalue);       
17     }
