Suppose you have a custom section as

Then you can change the value as

using System.Configuration;

namespace YourNamespace
{
    public class CustomSettingsSection : ConfigurationSection
    {
        [ConfigurationProperty("Setting1", DefaultValue = "Value1", IsRequired = false)]
        public string Setting1
        {
            get { return (string)this["Setting1"]; }
            set { this["Setting1"] = value; }
        }

        [ConfigurationProperty("Setting2", DefaultValue = "Value2", IsRequired = false)]
        public string Setting2
        {
            get { return (string)this["Setting2"]; }
            set { this["Setting2"] = value; }
        }
    }
}
using System;
using System.Configuration;

class Program
{
    static void Main()
    {
        // Load the configuration file
        Configuration configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        // Access the custom section
        CustomSettingsSection customSettings = (CustomSettingsSection)configuration.GetSection("customSettings");

        // Modify the values
        customSettings.Setting1 = "NewValue1";
        customSettings.Setting2 = "NewValue2";

        // Save the changes
        configuration.Save(ConfigurationSaveMode.Modified);

        Console.WriteLine("Custom settings updated successfully.");
    }
}

static void AddUpdateCustomSection(string key, string value)
{
    try
    {
        var configFile = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        var settings = ((AppSettingsSection)configFile.GetSection("MyCustomSection")).Settings;
        if (settings[key] == null)
        {
            settings.Add(key, value);
        }
        else
        {
            settings[key].Value = value;
        }
        configFile.Save(ConfigurationSaveMode.Modified);
        ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
    }
    catch (ConfigurationErrorsException)
    {
        Console.WriteLine("Error");
    }
}

AddUpdateCustomSection("Key1", "Value123");
AddUpdateCustomSection("Key3", "Value3");

Hi Naveen,

Your image is missing !!!.

To change the values in a custom section in the app.config file, you need to follow these steps:
1. Locate the app.config file in your project. It is usually located in the root directory of your project.
2. Open the app.config file in a text editor or in Visual Studio.
3. Find the custom section you want to modify. Custom sections are defined in the element and have a specific name and structure.
4. Locate the section you want to modify and find the corresponding
  element. This element defines the structure and properties of the custom section.
5. Inside the
  element, you will find the properties or elements that you want to change. Modify the values of these properties according to your requirements.
6. Save the changes to the app.config file.
Here is an example of a custom section in the app.config file:
```
  
    
  
  
  
    Value1
    Value2
  
```
In this example, you can change the values of Setting1 and Setting2 inside the element.

Remember to save the changes and rebuild your project for the modifications to take effect.
