I have the following code in C# below:

short* gArray = stackalloc short[3 * 256];

would like the equivalent in VB.net

I tried to do the conversion, with some different online tools, but it only returns me as a type of Invalid Syntax and / or does not exist for the VB.net syntax structure.

If it is possible to chat between syntaxes, as I do in a simplified way (any other types of code, such as Integers, Booleans, among others)

This is the complete code used in C#

public static unsafe bool SetBrightness(int brightnessValue)
{
    if (brightnessValue > 255)
        brightnessValue = 255;
    if (brightnessValue < 0)
        brightnessValue = 0;
    short* gArray = stackalloc short[3 * 256];
    short* idx = gArray;
    for (int j = 0; j < 3; j++)
    {
        for (int i = 0; i < 256; i++)
        {
            int arrayVal = i * (brightnessValue + 128);
            if (arrayVal > 65535)
                arrayVal = 65535;
            *idx = (short)arrayVal;
            idx++;
        }
    }
}

    That's unsafe code. There is no such thing in VB.NET. Commented Mar 9, 2021 at 18:40

    Does this answer your question? How can I use unsafe code in VB.Net? Commented Mar 9, 2021 at 18:43
  • There is some alternative, at least reading this social.msdn.microsoft.com/Forums/en-US/… but if it works for you probably depends on your exact context Commented Mar 9, 2021 at 18:44
  • In general, you shouldn't care about where memory is allocated, either in C# or VB.NET. Unsafe code in C# only exists for very specific use cases. Commented Mar 9, 2021 at 18:47
  • I updated my question by inserting the context code using it in my application, so that you can better understand what I want ... only if conversion is possible or not, use the same function as C# in VB.net Commented Mar 9, 2021 at 19:04
