C#操作ini文件的帮助类-C#/.NET开发

这篇文章介绍了C#操作ini文件的帮助类，文中通过示例代码介绍的非常详细。对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

.ini 文件是Initialization File的缩写，即初始化文件，是windows的系统配置文件所采用的存储格式，统管windows的各项配置，一般用户就用windows提供的各项图形化管理界面就可实现相同的配置了。但在某些情况，还是要直接编辑ini才方便，一般只有很熟悉windows才能去直接编辑。

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"));
