示例

下面的代码示例演示如何使用 PrimaryScreen 属性和 GetWorkingArea 方法。此方法需要包含名为的按钮的 Button1窗体。

// This method will adjust the size of the form to utilize // the working area of the screen. private: void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ ) { // Retrieve the working rectangle from the Screen class // using the PrimaryScreen and the WorkingArea properties. System::Drawing::Rectangle workingRectangle = Screen::PrimaryScreen->WorkingArea; // Set the size of the form slightly less than size of // working rectangle. this->Size = System::Drawing::Size( workingRectangle.Width - 10, workingRectangle.Height - 10 ); // Set the location so the entire form is visible. this->Location = System::Drawing::Point( 5, 5 ); } // This method will adjust the size of the form to utilize // the working area of the screen. private void Button1_Click(System.Object sender, System.EventArgs e) { // Retrieve the working rectangle from the Screen class // using the PrimaryScreen and the WorkingArea properties. System.Drawing.Rectangle workingRectangle = Screen.PrimaryScreen.WorkingArea; // Set the size of the form slightly less than size of // working rectangle. this.Size = new System.Drawing.Size( workingRectangle.Width-10, workingRectangle.Height-10); // Set the location so the entire form is visible. this.Location = new System.Drawing.Point(5, 5); } ' This method will adjust the size of the form to utilize ' the working area of the screen. Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click ' Retrieve the working rectangle from the Screen class ' using the PrimaryScreen and the WorkingArea properties. Dim workingRectangle As System.Drawing.Rectangle = _ Screen.PrimaryScreen.WorkingArea ' Set the size of the form slightly less than size of ' working rectangle. Me.Size = New System.Drawing.Size(workingRectangle.Width - 10, _ workingRectangle.Height - 10) ' Set the location so the entire form is visible. Me.Location = New System.Drawing.Point(5, 5) End Sub 注解
