提高.NET Compact Framework 1.0应用程序的窗体加载性能

减少方法调用

this .textBox1.Location = new Point( 10 , 20 );
this .textBox1.Size = new Size( 72 , 23 );

换成

this .textBox1.Bounds = new Rectangle( 10 , 20 , 72 , 23 );


不要把子控件加到父控件的Controls集合,通过Parent来控制

// Beforeoptimization
// Createanewpanelandtextboxcontrol
Panelpanel1 = new Panel();
TextBoxtextBox1
= new TextBox();
// SettheTextpropertyoftheTextBoxcontrol
textBox1.Text = " MyText " ;
// AddtheTextBoxtothePanel'scontrolcollection
panel1.Controls.Add( this .textBox1);
// AddthePaneltotheForm'scontrolcollection
this .Controls.Add(panel1);
...
// Addsubsequentcontrolshere

换成

// Afteroptimization
// Createanewpanelandtextboxcontrol
Panelpanel1 = new Panel();
TextBoxtextBox1
= new TextBox();
// ParentthePaneltothecurrentForm
this .panel1.Parent = this ;
// ParenttheTextBoxtothePanel
this .textBox1.Parent( this .panel1);
// SettheTextpropertyoftheTextBoxcontrol
textBox1.Text = " MyText " ;
...
// Addsubsequentcontrolshere


听说使用这两个方法修改窗体设计器生成的代码后,可以提高55%的窗体加载性能。不过,这样修改后的窗体,是否还能再用窗体设计器编辑?有多少人愿意这样做?
