将现有属性转换为 CustomAttributeBuilder 以插入到动态生成的类中

Question

我试图找出采用以下类的最佳方法：

public class ModelX {
    [TheAttribute(1, "two")]
    [SomeOtherAttribute(Three.Four)]
    public string Foo {get;set;}

并将这些复制到

public class DynamicallyCreatedModelX {
    [TheAttribute(1, "two")]
    [SomeOtherAttribute(Three.Four)]
    public string Foo {get;set;}

我不是将数据从已知类传递到动态类的最佳方法。

Answer 1

设置属性（或任何成员）的属性可以如下所示：

PropertyBuilder property = typeBuilder.DefineProperty(...);
property.SetCustomAttribute(new CustomAttributeBuilder(typeof(TheAttribute).GetConstructor(new Type[] { typeof(int), typeof(string) }), new object[] { 1, "two" }));
property.SetCustomAttribute(new CustomAttributeBuilder(typeof(SomeOtherAttribute).GetConstructor(new Type[] { typeof(Three.Four) }), new object[] { Three.Four }));
