(一). 功能

         操作配置文件[*.ini]类

(二). 代码

     1. 核心类文件 INIFILE.cs 代码

 1 /// <summary>
 2 /// INIFILE 操作类
 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     //要访问的文件路径
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("没有设置路径");
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("没有设置路径");
44         }
45         StringBuilder sb = new StringBuilder();
46         int i = GetPrivateProfileString(strSection, strKey, "", sb, 255, this.FilePath);
47         return sb.ToString();
48     }
49 }
2. 后台调用文件 INIFile.aspx.cs 代码

 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     }
