C＃设置下拉列表默认值

Question

我正在Form.Designer.cs中设置下拉列表的默认值，但是当我在设计窗口中更改此对象或什至另一个对象的位置时，此行消失，并且下拉列表不显示任何值。

        this.comboBox2.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;
        this.comboBox2.Enabled = true;
        this.comboBox2.FormattingEnabled = true;
        this.comboBox2.Items.AddRange(new object[] {
        "beam center",
        "force application"});
        this.comboBox2.Location = new System.Drawing.Point(402, 258);
        this.comboBox2.Name = "comboBox2";
        this.comboBox2.Size = new System.Drawing.Size(121, 21);
        this.comboBox2.TabIndex = 45;
        this.comboBox2.SelectedIndex = 0;

您知道我该如何解决吗？预先感谢。

将其从设计器生成的代码中移出并移至Form_Load之类的位置
