C# 控制台程序（命令行程序）设置字体颜色，窗口宽高，光标行数

控制台程序（命令行程序）设置窗口宽度高度，如下代码：

            Console.WriteLine(Console.WindowHeight);
            Console.WriteLine(Console.BufferHeight);
            Console.ReadKey();
            Console.Title = "Test";//设置窗口标题
            Console.WindowWidth = 120;
            Console.BufferHeight = 1000;
            Console.WriteLine(Console.WindowWidth);
            Console.WriteLine(Console.WindowHeight);
            Console.WriteLine("---------------------");
            Console.WriteLine(Console.BufferWidth);
            Console.WriteLine(Console.BufferHeight);

设置窗口字体颜色和背景颜色：

            Console.BackgroundColor = ConsoleColor.Blue; //设置背景色
            Console.ForegroundColor = ConsoleColor.White; //设置前景色，即字体颜色
            Console.WriteLine("第一行白蓝.");
            Console.ResetColor(); //将控制台的前景色和背景色设为默认值
            Console.BackgroundColor = ConsoleColor.Green;
            Console.ForegroundColor = ConsoleColor.DarkGreen;
            string str = "第三行 绿暗绿";
            Console.WriteLine(str.PadRight(Console.BufferWidth - (str.Length % Console.BufferWidth))); //设置一整行的背景色
            Console.ResetColor();

//显示出console中支持的背景色及前景色

        static void ShowColor()
        {
            Type type = typeof(ConsoleColor);
            Console.ForegroundColor = ConsoleColor.White;
            foreach (string name in Enum.GetNames(type))
            {
                Console.BackgroundColor = (ConsoleColor)Enum.Parse(type, name);
                Console.WriteLine(name);
            }

            Console.BackgroundColor = ConsoleColor.Black;
            foreach (string name in Enum.GetNames(type))
            {
                Console.ForegroundColor = (ConsoleColor)Enum.Parse(type, name);
                Console.WriteLine(name);
            }

            foreach (string bc in Enum.GetNames(type))
            {
                Console.BackgroundColor = (ConsoleColor)Enum.Parse(type, bc);
                foreach (string fc in Enum.GetNames(type))
                {
                    Console.ForegroundColor = (ConsoleColor)Enum.Parse(type, fc);
                    Console.WriteLine("bc="+bc+",fc="+fc);
                }
                Console.WriteLine();
            }
        }

计算当前光标所在的行数，针对于Console.BufferHeight的值，代码如下：

            ShowColor();
            int m = Console.CursorTop;//查看当前行号Console.BufferHeight 
            ShowColor();
            int n = Console.CursorTop;
            ShowColor();
            int o = Console.CursorTop;
            Console.ReadKey();
