INI file concept
INI is a file with the extension "INI". In fact, it is a text file that can be opened with Notepad. It mainly stores the choices made by the user or various parameters of the system.
The C# read and write ini file is actually not an ordinary text file. It has its own structure. It consists of several paragraphs (SECTION). Under each bracketed title, there are several keywords (KEYWORD) starting with a single word and An equal sign, the right side of the equal sign is the value of the keyword (VALUE), for example,
[Section1]
KeyWord1 = Value1
KeyWord2 = Value2
...
[Section2]
KeyWord3 = Value3
KeyWord4 = Value4
INI file reading operation
There is no class to directly read and write INI in the C# namespace. Although there is no class in C#, there are Win32 API functions in the file "kernel32.dll" -WritePrivateProfileString() and GetPrivateProfileString()
class file
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
namespace Files
{
class FilesINI
{
// 声明INI文件的写操作函数 WritePrivateProfileString()
[System.Runtime.InteropServices.DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
// 声明INI文件的读操作函数 GetPrivateProfileString()
[System.Runtime.InteropServices.DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, System.Text.StringBuilder retVal, int size, string filePath);
/// 写入INI的方法
public void INIWrite(string section, string key, string value,string path)
{
// section=配置节点名称，key=键名，value=返回键值，path=路径
WritePrivateProfileString(section, key, value, path);
}
//读取INI的方法
public string INIRead(string section, string key,string path)
{
// 每次从ini中读取多少字节
System.Text.StringBuilder temp = new System.Text.StringBuilder(255);
// section=配置节点名称，key=键名，temp=上面，path=路径
GetPrivateProfileString(section, key, "", temp, 255, path);
return temp.ToString();
}
//删除一个INI文件
public void INIDelete(string FilePath)
{
File.Delete(FilePath);
}
}
}

}
INI file modification operation
Modify IP
private void button1_Click(object sender, EventArgs e)
{
FilesINI ConfigINI = new FilesINI();
ConfigINI.INIWrite("Fanuc机器人控制参数", "IP", textBox1.Text, INIPath);
}
INI file writing operation
Add new configuration node [KUKA robot control parameters]
private void button1_Click(object sender, EventArgs e)
{
FilesINI ConfigINI = new FilesINI();
ConfigINI.INIWrite("KUKA机器人控制参数", "IP", textBox1.Text, INIPath);
}
Under a certain configuration node, add the new keyword Angle
private void button1_Click(object sender, EventArgs e)
{
FilesINI ConfigINI = new FilesINI();
ConfigINI.INIWrite("KUKA机器人控制参数", "Angle", textBox1.Text, INIPath);
}
