这篇文章主要介绍了C#怎么实现读写ini文件，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
1.创建一个C#项目
2.创建一个ini文件
在Debug目录下创建一个ini文件，写入下面内容，注意编码格式用ANSI。
[Information]
Name=周星星
Gender=男
Age=55
Region=香港
3.创建一个winform界面
如下图
4.添加一个ini管理类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
namespace Test1
{
public static class IniFunc
{
/// <summary>
/// 获取值
/// </summary>
/// <param name="section">段落名</param>
/// <param name="key">键名</param>
/// <param name="defval">读取异常是的缺省值</param>
/// <param name="retval">键名所对应的的值，没有找到返回空值</param>
/// <param name="size">返回值允许的大小</param>
/// <param name="filepath">ini文件的完整路径</param>
/// <returns></returns>
[DllImport("kernel32.dll")]
private static extern int GetPrivateProfileString(
string section,
string key,
string defval,
StringBuilder retval,
int size,
string filepath);
/// <summary>
/// 写入
/// </summary>
/// <param name="section">需要写入的段落名</param>
/// <param name="key">需要写入的键名</param>
/// <param name="val">写入值</param>
/// <param name="filepath">ini文件的完整路径</param>
/// <returns></returns>
[DllImport("kernel32.dll")]
private static extern int WritePrivateProfileString(
string section,
string key,
string val,
string filepath);
/// <summary>
/// 获取数据
/// </summary>
/// <param name="section">段落名</param>
/// <param name="key">键名</param>
/// <param name="def">没有找到时返回的默认值</param>
/// <param name="filename">ini文件完整路径</param>
/// <returns></returns>
public static string getString(string section, string key, string def, string filename)
{
StringBuilder sb = new StringBuilder(1024);
GetPrivateProfileString(section, key, def, sb, 1024, filename);
return sb.ToString();
}
/// <summary>
/// 写入数据
/// </summary>
/// <param name="section">段落名</param>
/// <param name="key">键名</param>
/// <param name="val">写入值</param>
/// <param name="filename">ini文件完整路径</param>
public static void writeString(string section, string key, string val, string filename)
{
WritePrivateProfileString(section, key, val, filename);
}
}
}
5.添加winform代码
双击winform界面，加入下面代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Test1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private string filename = null;
private void Form1_Load(object sender, EventArgs e)
{
filename = Application.StartupPath + "\\Config.ini";
}
/// <summary>
/// 读取
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Button_Read_Click(object sender, EventArgs e)
{
string names = IniFunc.getString("Information", "Name", null, filename);
string gender = IniFunc.getString("Information", "Gender", null, filename);
string age = IniFunc.getString("Information", "Age", null, filename);
string region = IniFunc.getString("Information", "Region", null, filename);
TextBox_Name.Text = names;
TextBox_Gender.Text = gender;
TextBox_Age.Text = age;
TextBox_Region.Text = region;
}
/// <summary>
/// 写入
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Button_Write_Click(object sender, EventArgs e)
{
string names = TextBox_Name.Text;
string gender = TextBox_Gender.Text;
string age = TextBox_Age.Text;
string region = TextBox_Region.Text;
IniFunc.writeString("Information", "Name", names, filename);
IniFunc.writeString("Information", "Gender", gender, filename);
IniFunc.writeString("Information", "Age", age, filename);
IniFunc.writeString("Information", "Region", region, filename);
}
/// <summary>
/// 清空
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void Button_Clear_Click(object sender, EventArgs e)
{
TextBox_Name.Text = string.Empty;
TextBox_Gender.Text = string.Empty;
TextBox_Age.Text = string.Empty;
TextBox_Region.Text = string.Empty;
}
}
}
