c# - 无法将方法添加到要在 InitializeComponent 期间调用的 Windows 窗体

Question

我正在使用 C# 中的 Visual Studio 2013 创建一个 GUI。我正在使用内置设计器，在创建我的 GUI 时，我添加了一个我想要包含 2 列的 listView 对象。我有以下代码:

partial class EmailSenderGUI
    {
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

    //My method that I made
    private void initRecipListView()
    {
        System.Console.WriteLine("Test");
        this.recipList.Columns.Add("Recipient", -2, System.Windows.Forms.HorizontalAlignment.Left);
        this.recipList.Columns.Add("Number of Reports", -2, System.Windows.Forms.HorizontalAlignment.Left);
    }

    #region Windows Form Designer generated code

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {

        this.recipList = new System.Windows.Forms.ListView();
        this.SuspendLayout();

        // 
        // recipList
        // 
        this.recipList.Location = new System.Drawing.Point(16, 32);
        this.recipList.Name = "recipList";
        this.recipList.Size = new System.Drawing.Size(376, 296);
        this.recipList.TabIndex = 1;
        this.recipList.UseCompatibleStateImageBehavior = false;
        this.recipList.View = System.Windows.Forms.View.Details;
        initRecipListView();
        // 
        // EmailSenderGUI
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(405, 400);
        this.Controls.Add(this.recipList);
        this.Name = "EmailSenderGUI";
        this.Text = "EmailSenderGUI";
        this.Load += new System.EventHandler(this.EmailSenderGUI_Load);
        this.ResumeLayout(false);
        this.PerformLayout();

    }

    #endregion

如您所见，我创建了方法 initRecipeListView 但是当我尝试运行代码时，我在设计窗口中收到以下错误:

Method 'System.Windows.Forms.Form.initRecipListView' not found.

为了清洁和可读性，我想将该方法保留在该部分类中，但它似乎不会让我这样做。有办法做到这一点吗？

据我所知，您将代码放在 EmailSenderGUI.Designer.cs 中 - 它应该在 EmailSenderGUI.cs 中，例如:

partial class EmailSenderGUI
{
    //My method that I made
    private void initRecipListView()
    {
        System.Console.WriteLine("Test");
        this.recipList.Columns.Add("Recipient", -2, System.Windows.Forms.HorizontalAlignment.Left);
        this.recipList.Columns.Add("Number of Reports", -2, System.Windows.Forms.HorizontalAlignment.Left);
    }
}

然后要在初始化时调用该方法，您需要处理表单 OnLoad 事件并从该处理程序调用该方法。
