生成自定义编译时间警告C# [英] Generating a custom compile time warning C#
问题描述
我使用的是VS2008,并希望根据属性上的自定义属性创建一个编译时间警告/错误(如果可能)。
目前感兴趣的两种情况:
[MyAttribute(typeof(MyClass)]
其中MyClass必须实现一个接口。目前我在属性的构造函数中断言这一点,但是这并不容易跟踪,到堆栈跟踪的性质:
public MyAttribute(Type MyClassType)
{
System.Diagnostics .Debug.Assert(typeof(MyInterface).IsAssignableFrom(MyClassType),
编辑器必须实现interface:+ typeof(MyInterface).Name);
}
<我感兴趣的第二种情况是我在属性中定义了一个类型,如果该类型实现了一个接口,然后是一个警告(例如:code>
)如果另一个属性不存在,则应显示。
IE if(MyClass.Implements(SomeInterface)&&&Exists(SomeAttibute)){Generate Warning}
[MyAttribute (MyClass)]
//注释下一行以生成警告
[Foo(Bar)]
谢谢!
解决方案您可以使用 PostSharp 。
我已经做了,并解释如何做此处
I'm using VS2008 and would like to create a compile time warning / error based on custom attributes on a property (if it is possible).
There are two cases which interest me currently:
[MyAttribute (typeof(MyClass)]
Where MyClass has to implement an interface. Currently I assert this in the constructor of the attribute, however this doesn't make it easy to track down, due to the nature of the stack trace:
public MyAttribute (Type MyClassType)
{
System.Diagnostics.Debug.Assert(typeof(MyInterface).IsAssignableFrom(MyClassType),
"Editor must implement interface: " + typeof(MyInterface).Name);
}
The second case which interests me is where I have a type defined in an attribute, if that type implements an interface, then a warning should be displayed if another attribute isn't present.
I.E. if (MyClass.Implements(SomeInterface) && !Exists(SomeAttibute)) { Generate Warning }
[MyAttribute(typeof(MyClass)]
// Comment next line to generate warning
[Foo ("Bar")]
Thanks!
解决方案 You can do that with PostSharp.
I've once done it, and explained how to do it here
