这样一段代码为什么设计页面要报错？
1 using System.Windows.Forms;
2 using System.Collections.Generic;
3 namespace WFAListViewer
4 {
5 partial class Form1
6 {

16 protected override void Dispose(bool disposing)
17 {
18 if (disposing && (components != null))

22 base.Dispose(disposing);

64 columnHeader2.Width = 142;
65
66 this.ListView1.Columns.Add(columnHeader1);
67 this.ListView1.Columns.Add(columnHeader2);
68
69 string[] foodList = new string[] { "Juice", "Coffee", "Cereal & Milk", "Fruit Plate", "Toast & Jelly", "Bagel & Cream Cheese" };
70 string[] foodPrice = new string[] { "1.09", "1.09", "2.19", "2.49", "1.49", "1.49" };
71
72 for (int count = 0; count < foodList.Length; count++)
73 {
74 ListViewItem listItem = new ListViewItem(foodList[count]);
75 listItem.SubItems.Add(foodPrice[count]);
76 ListView1.Items.Add(listItem);
77 }
78 this.Controls.Add(ListView1);
79
80
81 }
82
83 #endregion
84
85 private System.Windows.Forms.ListView ListView1;
86 private System.Windows.Forms.TextBox TextBox1;
87 }
88 }
主要就是插入foodList和foodprice那块，我理解是Form1是静态类？所以不允许实例化?
报的错是
The designer cannot process the code at line 72: for (int count = 0; count < foodList.Length; count++) { ListViewItem listItem = new ListViewItem(foodList[count]); listItem.SubItems.Add(foodPrice[count]); ListView1.Items.Add(listItem); } The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.
我印象中学C#的时候和vb差不多，设计页面里改什么代码页也会变什么，怎么现在会这样？还出来个
InitializeComponent啥啥的。。

Form1不是静态类，Winform分为设计时和运行时，默认地，designer.cs中的代码是由DesignerSerializer按字母的顺序生成的，当你拖控件时会执行序列化，当你打开Designer的时候，它会去反序列化，你自己写的无关代码并不能被反序列化，所以打开Designer出错，但是，编译可能会通过，运行也OK。尽量不要改动Designer.cs中的代码。

应该是循环的问题，现实的问题是拖动控件并不能满足所有的需求，所以才动手去修改Designer.cs对于我们这些新手来说，最好全都可以图形化处理，减少手动代码。
