(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 }(三). 示例代码下载
