如何使用Reflection.Emit创建静态字段

using System;
using System.Reflection;
using System.Reflection.Emit;

public class Program
{
    public static void Main()
    {
        // 创建动态程序集
        AssemblyName assemblyName = new AssemblyName("DynamicAssembly");
        AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(assemblyName, AssemblyBuilderAccess.RunAndSave);

        // 创建动态模块
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("DynamicModule", "DynamicModule.dll");

        // 创建动态类型
        TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicType", TypeAttributes.Public);

        // 创建静态字段
        FieldBuilder fieldBuilder = typeBuilder.DefineField("myField", typeof(string), FieldAttributes.Public | FieldAttributes.Static);

        // 生成类型
        Type dynamicType = typeBuilder.CreateType();

        // 使用动态类型
        dynamicType.GetField("myField").SetValue(null, "Hello, World!");
        Console.WriteLine(dynamicType.GetField("myField").GetValue(null));
    }
}
