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


// Before optimization


// Create a new panel and textbox control


Panel panel1 = new Panel();


TextBox textBox1 = new TextBox();


// Set the Text property of the TextBox control


textBox1.Text = "My Text";


// Add the TextBox to the Panel's control collection


panel1.Controls.Add(this.textBox1);


// Add the Panel to the Form's control collection


this.Controls.Add(panel1);


... // Add subsequent controls here
换成


// After optimization


// Create a new panel and textbox control


Panel panel1 = new Panel();


TextBox textBox1 = new TextBox();


// Parent the Panel to the current Form


this.panel1.Parent = this;


// Parent the TextBox to the Panel


this.textBox1.Parent(this.panel1);


// Set the Text property of the TextBox control


textBox1.Text = "My Text";


... // Add subsequent controls here

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？
