C#操作ini文件的帮助类
一、定义Class
using System; using System.Runtime.InteropServices; using System.Text; namespace IniDemo { public class IniFile { private string m_FileName; public string FileName { get { return this.m_FileName; } set { this.m_FileName = value; } } [DllImport("kernel32.dll")] private static extern int GetPrivateProfileInt(string lpAppName, string lpKeyName, int nDefault, string lpFileName); [DllImport("kernel32.dll")] private static extern int GetPrivateProfileString(string lpAppName, string lpKeyName, string lpDefault, StringBuilder lpReturnedString, int nSize, string lpFileName); [DllImport("kernel32.dll")] private static extern int WritePrivateProfileString(string lpAppName, string lpKeyName, string lpString, string lpFileName); public IniFile(string aFileName) { this.m_FileName = aFileName; } public IniFile() { } public int ReadInt(string section, string name, int def) { return IniFile.GetPrivateProfileInt(section, name, def, this.m_FileName); } public string ReadString(string section, string name, string def) { StringBuilder stringBuilder = new StringBuilder(2048); IniFile.GetPrivateProfileString(section, name, def, stringBuilder, 2048, this.m_FileName); return stringBuilder.ToString(); } public void WriteInt(string section, string name, int Ival) { IniFile.WritePrivateProfileString(section, name, Ival.ToString(), this.m_FileName); } public void WriteString(string section, string name, string strVal) { IniFile.WritePrivateProfileString(section, name, strVal, this.m_FileName); } public void DeleteSection(string section) { IniFile.WritePrivateProfileString(section, null, null, this.m_FileName); } public void DeleteAllSection() { IniFile.WritePrivateProfileString(null, null, null, this.m_FileName); } public string IniReadValue(string section, string name) { StringBuilder stringBuilder = new StringBuilder(256); IniFile.GetPrivateProfileString(section, name, "", stringBuilder, 256, this.m_FileName); return stringBuilder.ToString(); } public void IniWriteValue(string section, string name, string value) { IniFile.WritePrivateProfileString(section, name, value, this.m_FileName); } } }
二、调用方法
IniFile iniFile = new IniFile(Environment.CurrentDirectory + "\\LocalInf.ini"); //读取Local节点下M的值,默认为空值 string m = iniFile.ReadString("Local", "M", ""); //Local节点下写F=f iniFile.WriteString("Local", "F", "f"); //读取Local节点下IsSleep的字符串值,并转为bool类型值,给出默认值为False bool f = bool.Parse(iniFile.ReadString("Local", "IsSleep", "False")); //读取Local节点下的C的字符串值,并转为double类型值,给出默认值0 bool f = double.Parse(iniFile.ReadString("Local", "C", "0"));
到此这篇关于C#操作ini文件帮助类的文章就介绍到这了。希望对大家的学习有所帮助,也希望大家多多支持我们。
