C#学习1

首先来写个个helloworld吧，代码很短

namespace helloworld
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");  //将指定的字符串值（后跟当前行终止符）写入标准输出流
            Console.ReadLine();   //从标准输入流读取下一行字符
        }
    }
}

再来弄个简单的图形界面的，实现用户登录的提示

namespace Wpfhello
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("Welcome," + textname.InputHitTest);
        }
    }
}
