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
