在C#编程环境中：winform窗体应用程序是一种客户端程序，可以用来获取和显示数据。
首先新建一个窗体应用程序项目，在建完一个项目后可以看到有两个.cs类库文件：Form1.cs 和Program.cs，打开form1可以发现有Designer.cs和Form1文件，这里面前者存放的是放在窗体中控件的属性代码，而后面存放的是一些事件程序。当我们在窗体中添加一些控件的时候，designer中就会自动生成属性代码，而当我们想要设置该控件所要实现的事件时就可以Form1中编写。
下面是designer中所自动生成的自己在窗体中添加的控件属性代码，这些属性可以在下面的程序中修改也可以右击属性，直接在属性窗口中修改，并且在属性窗口中修改之后，这里的代码也会跟着自动产生；

namespace SHOWPIC
{
    partial class Form1
    {
        /// <summary>
        /// 必需的设计器变量。
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// 清理所有正在使用的资源。
        /// </summary>
        /// <param name=\"disposing\">如果应释放托管资源，为 true；否则为 false。</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

下面是在form1下编写的事件程序：

        public Form1()
        {
            InitializeComponent();
           
        }
        //当窗体在使用时进行的事件

            btnsave.Visible = false;
            textBox1.Visible = false;
            
        }
        //这里是登陆界面的按钮所实现的事件；
        private void btnload_Click(object sender, EventArgs e)
        {
          
            string xm = txtxm.Text;
            string xx = txtxx.Text;
            if (xm == \"猴哥\" && xx == \"方寸山\")

            FileStream fswrite = new FileStream(@\"C:\\Users\\WJ\\Desktop\\new.txt\", FileMode.Create,FileAccess.Write);
            byte[] array = System.Text.Encoding.Default.GetBytes(textBox1.Text);
            fswrite.Write(array, 0, array.Length);
            MessageBox.Show(\"写入成功\");
           
        }
    }
}

上面就是一个窗体文件的基本的属性设置以及事件的程序。这里我们观看整个项目工程，看到有两个.cs类库文件：Form1.cs 和Program.cs，这里Program.cs，就是我们的主程序入口，打开的代码初始的程序如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace SHOWPIC
{
    static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
          
        }
    }
}
