C# – First steps with C# and .NET – part 064.

This is a simple example of how to add to the Environment Variable variable Path a simple path read on the admin console. This code first retrieves the current system environment variables using the Environment.GetEnvironmentVariables method. Create a simple project with dotnet tool and add this source code:

using System;
using System.Collections;
using System.Collections.Specialized;
using System.Diagnostics;
using System.Runtime.InteropServices;

class Program
{
    static void Main(string[] args)
    {
        Console.Write("Enter the path to add: ");
        string pathToAdd = Console.ReadLine();
        Console.WriteLine($"Path to be added: {pathToAdd}");

        // Get the current system environment variables
        var envVariables = Environment.GetEnvironmentVariables(EnvironmentVariableTarget.Machine);

        // Add the new path to the PATH variable
        if (envVariables.Contains("Path"))
        {
            string currentPath = envVariables["Path"] as string;
            string newPath = $"{currentPath};{pathToAdd}";
            Environment.SetEnvironmentVariable("Path", newPath, EnvironmentVariableTarget.Machine);
            Console.WriteLine("New path added successfully!");
        }
        else
        {
            Console.WriteLine("PATH variable not found!");
        }
    }
}

using System;

using System.Collections;

using System.Collections.Specialized;

using System.Diagnostics;

using System.Runtime.InteropServices;

class Program

{

static void Main(string[] args)

{

Console.Write("Enter the path to add: ");

string pathToAdd = Console.ReadLine();

Console.WriteLine($"Path to be added: {pathToAdd}");

// Get the current system environment variables

var envVariables = Environment.GetEnvironmentVariables(EnvironmentVariableTarget.Machine);

// Add the new path to the PATH variable

if (envVariables.Contains("Path"))

{

string currentPath = envVariables["Path"] as string;

string newPath = $"{currentPath};{pathToAdd}";

Environment.SetEnvironmentVariable("Path", newPath, EnvironmentVariableTarget.Machine);

Console.WriteLine("New path added successfully!");

}

else

{

Console.WriteLine("PATH variable not found!");

}

C# – First steps with C# and .NET – part 063.

This new article presents a guide to running C# Azure functions in an isolated worker process. They comes also with: For complete examples, see the .NET 6 isolated sample project and the .NET Framework 4.8 isolated sample project Isolated worker processes are designed to run untrusted code in a sandboxed environment, which makes them a good choice for… Read More »

C# – First steps with C# and .NET – part 062.

This tutorial is very simple and presents some elements related to BufferedStream and MemoryStream. It is a simple example of using these functions that apply to .NET 7 and other versions. You need to change the disk letter with yours because on this I have mapped a drive to the letter E. Create a console… Read More »

Unity 3D – Testing custom editor – 001.

In this tutorial. I will show you how can be Unity Editor customized withSerializeField features. You need to open a new scene and add a new GameObject and rename it if you want. On this GameObject add a new script with a good name, I used the EditorScript001.cs file name. In this script I add… Read More »

C# – First steps with C# and .NET – part 061.

The difference between Build Solution, Rebuild Solution, and Clean Solution in Visual Studio comes from the development process. The Build solution will perform an incremental build. Compiles code files like DLL and EXE that are changed. Builds any assemblies which have changed files. If an assembly has no changes, it won’t be rebuilt. The Rebuild… Read More »

C# – First steps with C# and .NET – part 060.

A very useful tool for C# development is the dnSpy. dnSpy is a debugger and .NET assembly editor. You can use it to edit and debug assemblies even if you don’t have any source code available. You can find this tool in this GitHub project.

C# – First steps with C# and .NET – part 057.

If you like the NumPy package from python, then in this tutorial, I will show you how to use the NumSharp package. You can read more about this package on the GitHub webpage. Let’s see some definitions and save and load features with this package:

using System;
using NumSharp;

namespace NumSharp001
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World using the NumSharp package!");
            Console.WriteLine("basic definitions ");
            var array001 = np.full(5, 6); //[5, 5, 5 .. 5]
            Console.WriteLine("This array001 variable has these 6 values : " + array001);
            var array_zeros = np.zeros(6);
            Console.WriteLine("This array_zeros variable has these 6 values : " + array_zeros);
            var array_arange = np.arange(6);
            Console.WriteLine("This array_arange variable has these 6 values : " + array_arange);
            var matrix_3x3 = np.zeros((3, 3));
            Console.WriteLine("This matrix_3x3 variable has these values : " + matrix_3x3);
            Console.WriteLine("Save array to disk");
            Console.WriteLine("NumSharp cannot save arrays has more than int byteMaxSize = 2_147_483_591 elements");
            NDArray disk_array = new double[]{1,2,3};
            disk_array.ToString();
            np.Save((Array)disk_array, "my_array.npy");
            Console.WriteLine("Load array from disk.");
            NDArray load_array = np.Load<double[]>("my_array.npy");
            var disk_load_array = load_array.ToString();
            Console.WriteLine(disk_load_array);
        }
    }
}

using System;

using NumSharp;

namespace NumSharp001

{

internal class Program

{

static void Main(string[] args)

{

Console.WriteLine("Hello World using the NumSharp package!");

Console.WriteLine("basic definitions ");

var array001 = np.full(5, 6); //[5, 5, 5 .. 5]

Console.WriteLine("This array001 variable has these 6 values : " + array001);

var array_zeros = np.zeros(6);

Console.WriteLine("This array_zeros variable has these 6 values : " + array_zeros);

var array_arange = np.arange(6);

Console.WriteLine("This array_arange variable has these 6 values : " + array_arange);

var matrix_3x3 = np.zeros((3, 3));

Console.WriteLine("This matrix_3x3 variable has these values : " + matrix_3x3);

Console.WriteLine("Save array to disk");

Console.WriteLine("NumSharp cannot save arrays has more than int byteMaxSize = 2_147_483_591 elements");

NDArray disk_array = new double[]{1,2,3};

disk_array.ToString();

np.Save((Array)disk_array, "my_array.npy");

Console.WriteLine("Load array from disk.");

NDArray load_array = np.Load<double[]>("my_array.npy");

var disk_load_array = load_array.ToString();

Console.WriteLine(disk_load_array);

}

The result of this running source code will create… Read More »
