PostSharp 不能使用具有 > 127 个属性的匿名类型

Question

问题已在 PostSharp 4.3.27 中修复

给定以下 C# 代码

 var obj = new
 {
     p0 = 0,
     p1 = 1
     p2 = 2,
     // and so on until 127 ...
     p127 = 127
 }

我在尝试构建启用了 PostSharp 的项目时遇到此错误：

Invalid value 128 for enumeration ^Bw+U+DEY6J8e at location element type in type signature.

似乎有点意义，但我不熟悉 PostSharp 内部结构。

删除 p127 工作正常。还有其他人遇到过这个限制吗？

Answer 1

MulticastTargets 枚举

可以应用多播自定义属性 (MulticastAttribute) 的目标种类。

所以 InstanceConstructor 的最大值是 128

Answer 2

这已在 PostSharp 4.3.27 中修复
