Question

我一直在用Java编写大量代码，发现创建控制台或表单应用程序非常容易。事实上，所有人要做的就是添加一个表单并显示该表单。简单就像一个cookie，可以这么说。但是现在我有一个很大的项目出现在Visual C＃中，我还没有那么多使用它。我想，我不确定我是否正确，但控制台应用程序是C＃就是这样一个控制台应用程序，它不能接受任何鼠标动作事件。我希望能够从表单内部向C＃添加控件，就像在Java中一样。添加按钮或添加菜单。但是在C＃中有几个打开的文件，属性，assemblyinfo.cs，form1.cs等。下面的代码是表单designer.cs。

那么从编程的角度来看，从设计的视觉角度来看，添加组件的最佳方式是什么？

namespace WindowsFormsTestMenuApplication
{
    partial class Form1
    {
        /// <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);
        }

        #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()

Answer 1

听起来像是一般的设计/方法问题。为什么不在WinForms上使用WPF？为您提供Visual Studio中非常方便的设计师。您可以以WYSIWYG风格轻松构建GUI。支持数据绑定，一旦熟悉，非常方便。但是，稍后您仍然可以在运行时添加控件等，请参阅Breems的答案。注意：如果您使用WPF，如果要从除Windows之外的其他线程添加控件，则需要使用Windows的调度程序。

Answer 2

WinForms控件是常规对象，就像AWT或Swing一样。

您可以创建new ToolStripItem()，设置其属性，然后将其添加到DropDownItems集合。

Answer 3

您是否尝试在运行时添加控件？如果是这样，正如SLaks所说，您只需创建一个新的控件实例并将其添加到表单中。

 // Add a menustrip to the form.
 MenuStrip menuStrip = new MenuStrip();
 menuStrip.Dock = DockStyle.Top;
 this.Controls.Add(menuStrip);

否则，为什么不利用可视化设计器向表单添加控件？
