Я написал преобразование HEX в RGB на C#, и ввод/вывод консоли терминала библиотеки Crayon не может понять значение мето ⇐ C#

[Гость]

I have seen the question How to convert Hex to RGB?, but their answers were not what I looked for. I also have seen the following questions:

• Convert ARGB hex string to RGB
• How do I get the color from a hexadecimal color code using .NET?

But I was not looking for these answers.

I use C#/Nuget library Crayon that allows me to define a colour for the console output using ANSI escape codes.

I wrote a small code in C# to convert the hexadecimal code colour to the RGB colour and I assigned the method value to Crayon's libray input/output.

Код: Выделить всё

static string HexToRGBColour(string hex)  {   int r = Convert.ToInt32(hex.Substring(1, 2), 16);   int g = Convert.ToInt32(hex.Substring(3, 2), 16);    int b = Convert.ToInt32(hex.Substring(5, 2), 16);      return r + ", " + g + ", " + b; } 

I assigned the method and its value to the new variable:

Код: Выделить всё

var goldenYellow = HexToRGBColour("#B38D1E"); Console.WriteLine($"The RGB of #B38D1E is {goldenYellow}"); 

It resulted as

Код: Выделить всё

179, 141, 30

and it was correct.

It worked fully.

But I assigned them to Crayon's library

Код: Выделить всё

Rgb()

input/output and it failed.

The original code:

Код: Выделить всё

Console.WriteLine($"{Rgb(179, 141, 30).Text("Preview of the colour")}"); 

It worked fully.

I wanted to get rid of the RGB, and use to the hexadecimal code instead. Here is the modified code with two alternatives:

Код: Выделить всё

Console.WriteLine($"{Rgb(goldenYellow).Text("Preview of the colour")}"); Console.WriteLine($"{Rgb(HexToRGBColour("#B38D1E")).Text("Preview of the colour")}"); 

The first code failed with a following error:

Код: Выделить всё

The error CS7036: There is no argument given that corresponds to the required parameter 'g' of 'Output.Rgb(byte, byte, byte)' 

The second code failed with the same error.

I expected that both these codes would become

Код: Выделить всё

Console.WriteLine($"{Rgb(179, 141, 30).Text("Preview of the colour")}")

.

Remember I use .NET Core 8 and Linux and that I want to use an OS-agnostic code.
