方法一：设置窗体属性
//程序启动路径，与生成程序的exe文件在同一目录下public String exePath = Application.StartupPath;//定义窗体宽高int screenWidth = 0;int screenHeight = 0; screenWidth = (int)System.Windows.SystemParameters.PrimaryScreenWidth; screenHeight = (int)System.Windows.SystemParameters.PrimaryScreenHeight;// 设置全屏 this.FormBorderStyle = FormBorderStyle.None; //设置窗体为无边框样式this.WindowState = FormWindowState.Maximized; //最大化窗体this.Left = 0;this.Top = 0;this.Width = screenWidth;this.Height = screenHeight;//窗体背景图this.BackgroundImage = Image.FromFile(exePath + "文件名");
方案二：设置窗体尺寸
//程序启动路径，与生成程序的exe文件在同一目录下 public String exePath = Application.StartupPath;//窗口左上角位置public Point m_formAutographShowPos;//设置窗体尺寸this.Width = (int)System.Windows.SystemParameters.PrimaryScreenWidth;this.Height = (int)System.Windows.SystemParameters.PrimaryScreenHeight;this.ClientSize = new System.Drawing.Size(Width, Height);//计算初始位置m_formAutographShowPos.X = 0; m_formAutographShowPos.Y = 0; Location = m_formAutographShowPos;//窗体背景图this.BackgroundImage = Image.FromFile(exePath + "文件名");
