Ｃ#Console.Write在控制檯上輸出不類型（顏色）的信息

我們在開發過程中，有時候需要將不同的信息用不同的顏色輸出，方便我們關注不同類型的信息。下面擴展了Console.Write一系列方法。

    /// <summary>
    /// 控制檯幫助類
    /// </summary>
    public static class ConsoleHelper
    {

        static void WriteColorLine(string str, ConsoleColor color)
        {
            ConsoleColor currentForeColor = Console.ForegroundColor;
            Console.ForegroundColor = color;
            Console.WriteLine(str);
            Console.ForegroundColor = currentForeColor;
        }

        /// <summary>
        /// 打印錯誤信息
        /// </summary>
        /// <param name="str">待打印的字符串</param>
        /// <param name="color">想要打印的顏色</param>
        public static void WriteErrorLine(this string str, ConsoleColor color = ConsoleColor.Red)
        {
            WriteColorLine(str, color);
        }

        public static void WriteWarningLine(this string str, ConsoleColor color = ConsoleColor.Yellow)
        {
            WriteColorLine(str, color);
        }
        /// <summary>

        public static void WriteInfoLine(this string str, ConsoleColor color = ConsoleColor.White)
        {
            WriteColorLine(str, color);
        }

        {
            WriteColorLine(str, color);
        }
    }
