C# Console window, Escape Sequences Not Working-CodePudding

When I write code to write an escape sequence: Console.WriteLine("\x1b[94m Blue Text \x1b[0m");

The code prints as: ←[94m Blue Text ←[0m

Does anyone know how this is caused? I am on .NET 6.0

I tried writing the escape sequence in a variable but this doesn't change anything. When I use Console.Clear(); and rewrite the code with the same window it sometimes works.

Escape sequences are special characters that are used to represent certain actions, such as changing the text color or moving the cursor. These sequences are typically written using the backslash character () followed by a letter or symbol.

In your code, you are using the escape sequence "\x1b" to change the text color to blue. This escape sequence is not recognized by the .NET Console class, which is why you are seeing the text "←[94m" instead of the expected result.

To change the text color in the .NET Console, you can use the "\u001b" escape sequence followed by the desired color code. For example, here is how you can print blue text:

Console.WriteLine("\u001b[94mBlue Text\u001b[0m");

Output:

Keep in mind that this will only work if the console window supports ANSI escape codes. If the console window does not support ANSI escape codes, the text color will not change.

You can also use the .NET Console class's ForegroundColor and BackgroundColor properties to change the text color.

You may need to use the Console.OutputEncoding property to set the encoding for the console output. Depending on your system, you may need to set it to Encoding.UTF8. This will ensure the escape sequences will be interpreted correctly.

For example:

// Set encoding to UTF-8
Console.OutputEncoding = Encoding.UTF8;

// Write escape sequence
Console.WriteLine("\x1b[94m Blue Text \x1b[0m");
