这样一段代码为什么设计页面要报错？

72             for (int count = 0; count < foodList.Length; count++)

75                 listItem.SubItems.Add(foodPrice[count]);
76                 ListView1.Items.Add(listItem);
77             }
78             this.Controls.Add(ListView1);

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。。
