This article mainly introduces how to read and write ini files in C#. It has certain reference value. Interested friends can refer to it. I hope you can learn a lot after reading this article. Let's take a look at it.

1. Create a C# project 2. Create an ini file

Create an ini file in the Debug directory, write the following, and note that the encoding format is ANSI.

[Information]

Name= Zhou Xing

Gender= male

Age=55

Region= Hong Kong

3. Create a winform interface

The figure below is as follows

4. Add an ini management class 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 {/ get the value / segment name / key name / / read the default value of the exception is / the value corresponding to the key name Did not find the full path to return null / the size allowed for the ini file / [DllImport ("kernel32.dll")] private static extern int GetPrivateProfileString (string section, string key, string defval, StringBuilder retval, int size, string filepath) / / write / / write / / paragraph name to be written / / key name to be written / / write value / full path to the ini file / [DllImport ("kernel32.dll")] private static extern int WritePrivateProfileString (string section String key, string val, string filepath) / get data / key name / / default value returned if not found / full path of ini file / 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 () } / write data / Segment name / / key name / / write value / ini file full path public static void writeString (string section, string key, string val, string filename) {WritePrivateProfileString (section, key, val, filename) } 5. Add winform code

Double-click the winform interface and add the following code

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" } / read / 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 } / write / 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) } / clear / 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;} Thank you for reading this article carefully.
