实训要求:
代码:
Test类:

对于ASP.NET控件(我使用了Calendar控件),您可以处理SelectionChanged事件…
[Markup] <asp:Calendar ID="Calendar1" runat="server" onselectionchanged="Calendar1_SelectionChanged"></asp:Calendar> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> [CodeBehind] protected void Calendar1_SelectionChanged(object sender,EventArgs e) { TextBox1.Text = Calendar1.SelectedDate.ToShortDateString(); }

C#实现计算器窗体程序
本文实例为大家分享了C#实现计算器窗体程序的具体代码,供大家参考,具体内容如下
功能设计
1、计算器中,添加 0-9 共十个数字键。
2、计算器中,增添 加、减、乘、除、等于五个功能键。
3、计算器中,增加四个功能键:x2,sqrt,log, ln 四个键,分别计算求平方,开方。
实现代码

C#用记事本编写简单WinForm窗体程序
平时我们编写WinForm程序经常使用VS进行拖控件的方式,这样做虽然简单,但是无法深入了解WinForm程序的本质。其实,用记事本也可以编写出VS编写的WinForm程序。还是直接看代码吧:
1、打开记事本,写入以下代码,另存为hello.cs文件
using System; using System.Windows.Forms; namespace Hello { public class Form1:Form { private System.Windows.Forms.Button btnClose; public Form1() { this.Text = "Form1窗体"; btnClose = new System.Windows.Forms.Button(); //将窗体挂起 this.SuspendLayout(); //设置按钮属性 this.btnClose.Location = new System.Drawing.Point(20,20); this.btnClose.Size = new System.Drawing.Size(100,25); this.btnClose.Name = "btnClose"; this.btnClose.Text = "按钮"; this.btnClose.UseVisualStyleBackColor = true; //设置按钮控件点击事件 this.btnClose.Click += new System.EventHandler(this.btnClose_Click); //将构造的控件添加到窗体Controls控件集合 this.Controls.Add(btnClose); } //按钮点击事件 private void btnClose_Click(object sender,EventArgs e) { this.Close(); } } public class Program { //程序入口 public static void Main() { Application.Run(new Form1()); } } }
2、在Windows搜索框输入 cmd,打开控制台,输入以下代码切换目录
cd C:\Windows\Microsoft.NET\Framework\v4.0.30319
3、目录切换完毕后,输入以下代码运行
csc.exe /out:e:\hello.exe e:\hello.cs
/out:e:\hello.exe用于指定可执行文件存放的目录和名称
e:\hello.cs用于指定源文件的文件路径

C#窗体程序实现全屏及取消全屏步骤
由于项目需要,需要用vs窗体程序实现播放视频的窗口的全屏和取消全屏。
具体实现界面如图:
这是初始状态,视频框的右上角就是控制全屏的按钮
这是全屏后的状态,此时全屏按钮变成了取消全屏的样式
注:为了界面的美观我的全屏并没有把左边的那些控件也盖住,但是是可以设置的,下边代码部分我会进行讲解。
1、首先说明一下我所用的控件及我的项目中控件的名称,以便大家理解。
显示视频的黑框是一个picturebox即代码中的VideoPlayWnd,全屏/取消全屏是一个button即代码中的button4
2、具体代码如下:
全屏和取消全屏是一个按钮即button4
private Int16 zoom = -1;//用来控制点击此button4的时候,是需要全屏还是取消全屏 //视频窗口的缩放代码 private void button4_Click(object sender, EventArgs e) { if(zoom<0) { float w = this.Width - 210; //为了保证左边的控件不被挡上减了一个210 float h = this.Height - 50;//为了底下的按钮不被挡上,因为还要用到,因此减了50 this.VideoPlayWnd.Size = Size.Ceiling(new SizeF(w, h));//重新部署视频框即这个picturebox空间的长宽 VideoPlayWnd.Location = new System.Drawing.Point(210, 0);//视频框的左上角坐标,会发现与我上边减去的210一致(大家肯定都理解为什么我就不说了) button4.Location = new System.Drawing.Point(795, 0);//不能只有picturebox变了,这个button的位置也要保证和视频框同步,所以需要重设坐标 // button4.BackgroundImage = Image.FromFile(@"E:\lwj\addpersoninfo\addpersoninfo\Resources\退出全屏.png");//绝对路径(这是我测试的时候用的) button4.BackgroundImage = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + @"退出全屏.png");//AppDomain.CurrentDomain.BaseDirectory语句可以获取到你当前项目的bin目录,所以需要把图片放到对应目录下 zoom = 1;//全屏之后,再点击需要取消全屏,因此要改变zoom的值 } else { //以下为取消全屏,即还原自己的视频框和按钮,具体操作类似全屏,就不细致注释了 VideoPlayWnd.Location = new System.Drawing.Point(495, 360); this.VideoPlayWnd.Size = Size.Ceiling(new SizeF(323, 271)); button4.Location = new System.Drawing.Point(795, 360); button4.BackgroundImage = Image.FromFile(AppDomain.CurrentDomain.BaseDirectory + @"全屏.png"); zoom = -1;//取消全屏后再点击就要进行全屏,因此继续设为-1(保证小于0,以满足全屏操作的if条件) } }
以上代码中的按钮是给它加了一个全屏样式的背景图片,并在点击时切换背景图片。
补充知识:C# 窗体视频控件进入全屏模式和退出全屏模式
窗体控件进入全屏模式和退出全屏模式,视频播放的时候用到此功能。
工具类代码

调用方式
/// <summary> /// 全屏事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void UCVideo_DoubleClick(object sender, EventArgs e) { //全屏设置 //sdlVideo.SDL_MaximizeWindow(); fullScreenHelper = new CvNetVideo.Play.FullScreenHelper(this); fullScreenHelper.FullScreen(true); Console.WriteLine("Entrance FullScreen Mode"); } /// <summary> /// 按键弹起事件 /// </summary> private void UCVideo_KeyUp(object sender, KeyEventArgs e) { // ESC 退出全屏 if (e.KeyCode == Keys.Escape&& fullScreenHelper!=null) { fullScreenHelper.FullScreen(false); fullScreenHelper = null; Console.WriteLine("Exit FullScreen Mode"); } }
测试效果图
注意:在使用SDL的全屏操作过程中设置是无效的,播放视频过程中不能实现修改。代码如下:
public void SDL_MaximizeWindow() { Console.WriteLine("设置全屏"); SDL.SDL_MaximizeWindow(screen); SDL.SDL_SetWindowFullscreen(screen, SDL.SDL_GetWindowFlags(screen)); SDL.SDL_ShowWindow(screen); //int width, height; 获取最大窗口值 //SDL2.SDL.SDL_GetWindowMaximumSize(screen, out width, out height); 设置最大窗口值 //if (width>0&&height>0) //{ // SDL2.SDL.SDL_SetWindowMaximumSize(screen, width, height); // Console.WriteLine("设置全屏......成功!width=" + width + ",height=" + height); //} //else //{ // Console.WriteLine("设置全屏......失败!width=" + width + ",height=" + height); // SDL2.SDL.SDL_SetWindowMaximumSize(screen, w, h); //} }
工具代码功能改进
