public:
 static System::Drawing::Rectangle GetWorkingArea(System::Drawing::Point pt);
public static System.Drawing.Rectangle GetWorkingArea (System.Drawing.Point pt);
static member GetWorkingArea : System.Drawing.Point -> System.Drawing.Rectangle
Public Shared Function GetWorkingArea (pt As Point) As Rectangle

返回

Rectangle

一个 Rectangle,它指定工作区。 在各显示器都不包含指定点的多显示器环境中,将返回与该点最接近的显示器。

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 按钮的窗体 Button1

   // 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
