是的。请看这篇文章。这里有一个例子:

Console.BackgroundColor = ConsoleColor.Blue;
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine("White on blue.");

下面是一个优雅的实现，它使用了dotnet新的字符串插值特性。

[InterpolatedStringHandler]
public ref struct ConsoleInterpolatedStringHandler
{
    private static readonly Dictionary<string, ConsoleColor> colors;
    private readonly IList<Action> actions;

    static ConsoleInterpolatedStringHandler() =>
        colors = Enum.GetValues<ConsoleColor>().ToDictionary(x => x.ToString().ToLowerInvariant(), x => x);

    public ConsoleInterpolatedStringHandler(int literalLength, int formattedCount)
    {
        actions = new List<Action>();
    }

    public void AppendLiteral(string s)
    {
        actions.Add(() => Console.Write(s));
    }

    public void AppendFormatted<T>(T t)
    {
        actions.Add(() => Console.Write(t));
    }

    public void AppendFormatted<T>(T t, string format)
    {
        if (!colors.TryGetValue(format, out var color))
            throw new InvalidOperationException($"Color '{format}' not supported");

        actions.Add(() =>
        {
            Console.ForegroundColor = color;
            Console.Write(t);
            Console.ResetColor();
        });
    }

    internal void WriteLine() => Write(true);
    internal void Write() => Write(false);

    private void Write(bool newLine)
    {
        foreach (var action in actions)
            action();

        if (newLine)
            Console.WriteLine();
    }
}

要使用它，创建一个类，例如ExtendedConsole:

internal static class ExtendedConsole
{
    public static void WriteLine(ConsoleInterpolatedStringHandler builder)
    {
        builder.WriteLine();
    }

    public static void Write(ConsoleInterpolatedStringHandler builder)
    {
        builder.Write();
    }
}

然后，像这样使用它:

        var @default = "default";
        var blue = "blue";
        var green = "green";
        ExtendedConsole.WriteLine($"This should be {@default}, but this should be {blue:blue} and this should be {green:green}");

上面的注释都是可靠的响应，但是注意它们不是线程安全的。如果您正在用多个线程写入控制台，更改颜色将添加一个竞争条件，可能会产生一些奇怪的输出。不过修复起来很简单:

public class ConsoleWriter
{
    private static object _MessageLock= new object();

    public void WriteMessage(string message)
    {
        lock (_MessageLock)
        {
            Console.BackgroundColor = ConsoleColor.Red;
            Console.WriteLine(message);
            Console.ResetColor();
        }
    }
}

下面是我编写的一个简单方法，用于编写带有内联颜色变化的控制台消息。它只支持一种颜色，但它符合我的需要。

// usage: WriteColor("This is my [message] with inline [color] changes.", ConsoleColor.Yellow);
static void WriteColor(string message, ConsoleColor color)
{
    var pieces = Regex.Split(message, @"(\[[^\]]*\])");

    for(int i=0;i<pieces.Length;i++)
    {
        string piece = pieces[i];
        
        if (piece.StartsWith("[") && piece.EndsWith("]"))
        {
            Console.ForegroundColor = color;
            piece = piece.Substring(1,piece.Length-2);          
        }
        
        Console.Write(piece);
        Console.ResetColor();
    }
    
    Console.WriteLine();
}

我只是想在使用console。writeline()时调整文本颜色; 所以我不得不写

Console.ForegroundColor = ConsoleColor.DarkGreen;
Console.WriteLine("my message");
Console.ResetColor();

每次我想写点什么

所以我发明了我的WriteLine()方法，并一直在Program类中使用它而不是console。

public static void WriteLine(string buffer, ConsoleColor foreground = ConsoleColor.DarkGreen, ConsoleColor backgroundColor = ConsoleColor.Black)
{
   Console.ForegroundColor = foreground;
   Console.BackgroundColor = backgroundColor;
   Console.WriteLine(buffer);
   Console.ResetColor();
}

为了让它更简单，我还写了一个Readline()方法，像这样:

public static string ReadLine()
{
   var line = Console.ReadLine();
   return line ?? string.Empty;
}

现在我们要做的就是在控制台中写入或读取一些东西:

static void Main(string[] args) {
   WriteLine("hello this is a colored text");
   var answer = Readline();
}

是的。请看这篇文章。这里有一个例子:

Console.BackgroundColor = ConsoleColor.Blue;
Console.ForegroundColor = ConsoleColor.White;
Console.WriteLine("White on blue.");
