INI file Read Write C#

 class INIFile
{
    private string filePath;
        
    [DllImport("kernel32")]
    private static extern long WritePrivateProfileString(string section,
    string key,
    string val,
    string filePath);
  
    [DllImport("kernel32")]
    private static extern int GetPrivateProfileString(string section,
    string key,
    string def,
    StringBuilder retVal,
    int size,
    string filePath);
        
    public INIFile(string filePath)
    {
        this.filePath = filePath;
    }
  
    public void Write(string section, string key, string value)
    {
        WritePrivateProfileString(section, key, value.ToLower(), this.filePath);
    }
  
    public string Read(string section, string key)
    {
        StringBuilder SB = new StringBuilder(255);
        int i = GetPrivateProfileString(section, key, "", SB, 255, this.filePath);
        return SB.ToString();
    }
          
    public string FilePath
    {
        get { return this.filePath; }
        set { this.filePath = value; }
    }
}

INIFile inif = new INIFile("D:\\config.ini");
inif.Write("Database", "Devs", "sa");
INIFile inif = new INIFile("D:\\config.ini");
Console.WriteLine("The Value is:" +inif.Read("Database", "Devs"));

//https://midnightprogrammer.net/post/readwrite-settings-to-ini-file-using-c/

Change INI File:
Easy way is to use WritePrivateProfileString and GetPrivateProfileString functions
 of Kernel32.dll for reading and writing into INI file.

Example:

For Writing to INI:

[DllImport("kernel32.dll", EntryPoint = "WritePrivateProfileString")]
public static extern long WriteValueA(string strSection, 
                                       string strKeyName, 
                                       string strValue, 
                                       string strFilePath);
Usage:

 WriteValueA("SectionToWrite", "KeyToWrite", "Value", @"D:\INIFile.ini");
For Reading from INI:

[DllImport("kernel32.dll", EntryPoint = "GetPrivateProfileString")]
public static extern int GetKeyValueA(string strSection, 
                                      string strKeyName, 
                                      string strEmpty, 
                                      StringBuilder RetVal, 
                                      int nSize, 
                                      string strFilePath);
Usage:

StringBuilder temp = new StringBuilder(255);
int i = GetKeyValueA("TargetSection", "KeyToRead", string.Empty, temp, 255, @"D:\INIFile.ini");
string sValue = temp.ToString(); //desired value of the key

it's Tuesday, and like every Tuesday I have an update for you, with of all the new free tutorials I wrote:

What is a reverse proxy? Find out what is a reverse proxy and what is it useful for!

A simple nginx reverse proxy for serving multiple Node.js apps from subfolders. An example of using a reverse proxy.

How to solve the `util.pump is not a function` error in Node.js. I got this error while trying to run some old Node snippet I found on the Web, and here's how I solved it.

Serve an HTML page using Node.js. Find out how to serve an `index.html` HTML page using Node.js with no dependencies.

Gatsby, fix the "cannot find module gatsby-cli/lib/reporter" error. How I fixed a weird Error: Cannot find module gatsby-cli/lib/reporter error I got while creating a Gatsby site and finding the solution was not fast, so I wrote a post about it.

How to find the command that is using a port. You might want to start a server on a port, but the port is already taken by another server. Which one? Here's how to find out.

How to configure Nginx for HTTPS: How to set up HTTPS on your Web Server using Let's Encrypt.

I also published 2 videos on YouTube: How to create a loop in a React Component's JSX and Running React Tests Automatically in the Cloud with GitHub Actions! This last one is the one I'd recommend watching. I am not as consistent as I'd like to be with videos. It's something I want to improve: being better at making videos, since it's something I struggle with, and also being better at making more videos. The two things are linked, making more videos is the only way to improve the quality, as practice is essential. Anyway, if you subscribe to the channel I'm happy to have your encouragement!

Dijeta sa pasuljem je veoma popularna dijeta jer se za 7 dana može skinuti i do 5 kilograma! Sam pasulj je bogat lako svarljivim proteinima, vitaminima: B, C, E i PP zatim mineralima: kalcijumom, fosforom, bakrom, cinkom, gvožđem kao i aminokiselinama, a najzastupljenije su: triptofan, lizin, arginin, tirozin i metionin.

Dijeta sa pasuljem je odlična za hladniji deo godine jer sprečava blagu avitaminozu koja je karakteristična upravo za hladne dane i dijetni način ishrane. Pasulj ima i odlična dejstva na jetru i žučnu kesu – pomaže im da bolje rade, a kada je u pitanju digestivni trakt – možemo ga mirne duše nazvati pravim „čistačem“. U red pohvala ovoj namirnici ide i to što osnažuje kardiovaskularni sistem i poboljšava stanje i izgled kože. Preporučuje se da se posle dijete još nekoliko dana jede pasulj kao glavno jelo, a da se smanji unos hleba i slatkiša.

Važno: Za vreme dijete trebalo bi piti dosta tečnosti (najbolje čiste vode) i potpuno isključiti šećer i so. Svake večeri pre nego što odete u krevet popijte 1 šolju malomasnog jogurta ili još bolji izbor je kefir!

Obratite pažnju na jelovnik – iako pojedini dani izgledaju slično – postoje razlike koje su značajne. Što se kuvanja pasulja tiče, kuva se gust, sa što manje masnoće i poželjno je bez zaprške (naravno, začini se mogu dodati po ukusu).
