C#實現窗體全屏

方法一：設定窗體屬性

//程式啟動路徑，與生成程式的exe檔案在同一目錄下
public String exePath = Application.StartupPath;
//定義窗體寬高
int screenWidth = 0;
int screenHeight = 0;
screenWidth = (int)System.Windows.SystemParameters.PrimaryScreenWidth;
screenHeight = (int)System.Windows.SystemParameters.PrimaryScreenHeight;
// 設定全屏   
this.FormBorderStyle = FormBorderStyle.None;     //設定窗體為無邊框樣式
this.WindowState = FormWindowState.Maximized;    //最大化窗體
this.Left = 0;
this.Top = 0;
this.Width = screenWidth;
this.Height = screenHeight;
//窗體背景圖
this.BackgroundImage = Image.FromFile(exePath + "檔名");

 

方案二：設定窗體尺寸

//程式啟動路徑，與生成程式的exe檔案在同一目錄下
public String exePath = Application.StartupPath;
//視窗左上角位置
public Point m_formAutographShowPos;
//設定窗體尺寸
this.Width = (int)System.Windows.SystemParameters.PrimaryScreenWidth;
this.Height = (int)System.Windows.SystemParameters.PrimaryScreenHeight;
this.ClientSize = new System.Drawing.Size(Width, Height);

//計算初始位置
m_formAutographShowPos.X = 0;
m_formAutographShowPos.Y = 0;
Location = m_formAutographShowPos;
//窗體背景圖
this.BackgroundImage = Image.FromFile(exePath + "檔名");
