How can Winform place the code into memory?

In WinForm, one common way to put code into memory is by using delegates and Lambda expressions.

First, define a delegate type, such as Action or Func, choosing the appropriate one based on the needs. Next, use a Lambda expression to define the logic of the code within the delegate. Finally, execute the code by calling the delegate.

Here is a simple example:

using System;
using System.Windows.Forms;

namespace WinFormMemory
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnRunCode_Click(object sender, EventArgs e)
        {
            // 定义委托类型，这里使用无返回值的Action委托
            Action myCode;

            // 将代码逻辑定义在Lambda表达式中
            myCode = () =>
            {
                // 在内存中执行的代码
                MessageBox.Show("这是运行在内存中的代码");
            };

            // 调用委托执行代码
            myCode.Invoke();
        }
    }
}

In the example above, when the button btnRunCode is clicked, the code logic is defined in memory as a delegate myCode and executed by invoking the delegate. In this example, the code logic is to display a message box.

Please note that this is just a simple example, in actual applications more complex situations may need to be considered, such as passing parameters and handling exceptions.
