CodeDom使用笔记（三）

InitializeComponent方法是Visual Studio设计器自动生成的，注释中也有警告除非必要不要修改里面的代码，因为在改变页面设计后，所做的修改会被覆盖。
但是要生成代码就需要写出这里面的代码了，InitializeComponent方法内容分下面几部分：
1.组件容器components初始化
2.控件生成&设置属性（部分控件需要SuspendLayout，防止属性设置过程中造成闪烁）
3.画面本身生成&属性设置
4.部分控件ResumeLayout

例如，CodeDom代码如下：

// this.components = new System.ComponentModel.Container();CodeStatement createComponents = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "components"),new CodeObjectCreateExpression("System.ComponentModel.Container", new CodeExpression[]{}));cmm.Statements.Add(createComponents);//this.groupBox1 = new GroupBox(this.components);CodeStatement create = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), groupBox.Name),new CodeObjectCreateExpression("GroupBox",new CodeExpression[] {new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "components")}));cmm.Statements.Add(create);//((System.ComponentModel.ISupportInitialize)(this.groupBox1)).BeginInit();CodeStatement beginInit new CodeMethodInvokeExpression(new CodeCastExpression("System.ComponentModel.ISupportInitialize",new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName)),"BeginInit",new CodeExpression[] { });  cmm.Statements.Add(beginInit);//this.groupBox1.SuspendLayout();CodeStatement suspendLayout = new CodeMethodInvokeExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName),"SuspendLayout",new CodeExpression[] { });cmm.Statements.Add(suspendLayout);//this.groupBox1.Appearance.BackColor = System.Drawing.SystemColors.Control;CodeStatement backColor = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Appearance.BackColor"),new CodeSnippetExpression("System.Drawing.SystemColors.Control"));cmm.Statements.Add(backColor);//this.groupBox1.Appearance.Options.UseBackColor = true;CodeStatement useBackColor = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Appearance.Options.UseBackColor"),new CodeSnippetExpression("true"));cmm.Statements.Add(useBackColor);//Controls.Addforeach (Control ctrl in groupBox.Controls){CodeStatement addControl = new CodeMethodInvokeExpression(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Controls"), "Add",new CodeExpression[] { new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), childName)});cmm.Statements.Add(addControl);}//this.groupBox1.Dock = System.Windows.Forms.DockStyle.Fill;CodeStatement dock = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Dock"),new CodePropertyReferenceExpression(new CodeTypeReferenceExpression("System.Windows.Forms.DockStyle"), "Fill"));    cmm.Statements.Add(dock);//this.groupBox1.Location = new System.Drawing.Point(242, 54);CodeStatement location = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Location"),new CodeObjectCreateExpression(new CodeTypeReference("System.Drawing.Point"),new CodeExpression[]{new CodePrimitiveExpression(242),new CodePrimitiveExpression(54)}));  cmm.Statements.Add(location);//this.groupBox1.Name = "groupBox1";CodeStatement name = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Name"),new CodePrimitiveExpression("groupBox1"));cmm.Statements.Add(name);//this.groupBox1.Size = new System.Drawing.Size(233, 42);CodeStatement size = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Size"),new CodeObjectCreateExpression(new CodeTypeReference("System.Drawing.Size"),new CodeExpression[]{new CodePrimitiveExpression(233),new CodePrimitiveExpression(42)}));cmm.Statements.Add(size);//this.groupBox1.TabIndex = 7;CodeStatement tabIndex = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "TabIndex"),new CodePrimitiveExpression(7)); cmm.Statements.Add(tabIndex);//this.groupBox1.Text = "groupBox1";CodeStatement text = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName), "Text"),new CodePrimitiveExpression("groupBox1"));cmm.Statements.Add(text);//this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Inherit;CodeStatement autoScaleMode = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "AutoScaleMode"),new CodePropertyReferenceExpression(new CodeTypeReferenceExpression("System.Windows.Forms.AutoScaleMode"), "Inherit"));cmm.Statements.Add(autoScaleMode);//this.ClientSize = new System.Drawing.Size(534, 470);CodeStatement clientSize = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "ClientSize"),new CodeObjectCreateExpression(new CodeTypeReference("System.Drawing.Size"),new CodeExpression[]{new CodePrimitiveExpression(534),new CodePrimitiveExpression(470)}));cmm.Statements.Add(clientSize);//this.groupBox1.Controls.Add(XXX);CodeExpression ctrls = new CodeMethodInvokeExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "Controls"), "Add",new CodeExpression[]{new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrl.Name)});cmm.Statements.Add(ctrls);//this.Name = "Form2";CodeStatement name = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "Name"),new CodePrimitiveExpression(winForm.Text));cmm.Statements.Add(name);//this.Text = "Form2";CodeStatement text = new CodeAssignStatement(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), "Text"),new CodePrimitiveExpression(winForm.Text));cmm.Statements.Add(text);//((System.ComponentModel.ISupportInitialize)(this.group2)).EndInit();CodeStatement new CodeMethodInvokeExpression(new CodeCastExpression("System.ComponentModel.ISupportInitialize",new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName)),"EndInit",new CodeExpression[] { });  //this.group2.ResumeLayout(false);CodeStatement resumeLayout = new CodeMethodInvokeExpression(new CodePropertyReferenceExpression(new CodeThisReferenceExpression(), ctrlName),"ResumeLayout",new CodeExpression[] { new CodeSnippetExpression("false") });cmm.Statements.Add(resumeLayout);//this.ResumeLayout(false);CodeExpression resumeLayout = new CodeMethodInvokeExpression(new CodeThisReferenceExpression(), "ResumeLayout", new CodeExpression[]{new CodeSnippetExpression("false")});cmm.Statements.Add(resumeLayout);

其中ctrlName都是“groupBox1”。
每部分生成的代码就是上面的注释部分。
当然可以考虑将一些通用的属性设置提取为公用方法，如Name, Text, Location, Size, TabIndex等等。
