如何在C#中为类动态添加字段？

TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicClass", TypeAttributes.Public);

FieldBuilder fieldBuilder = typeBuilder.DefineField("DynamicField", typeof(string), FieldAttributes.Public);

Type dynamicType = typeBuilder.CreateType();
object dynamicObject = Activator.CreateInstance(dynamicType);

// 设置字段值
dynamicType.GetField("DynamicField").SetValue(dynamicObject, "Hello, World!");

// 获取字段值
string fieldValue = (string)dynamicType.GetField("DynamicField").GetValue(dynamicObject);
