(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 }
