自定义程序集属性 [英] Custom Assembly Attributes

问题描述

我想知道是否可以定义自定义程序集属性.现有属性的定义方式如下:

I would like to know if I can define custom assembly attributes. Existing attributes are defined in the following way:

[assembly: AssemblyTitle("MyApplication")]  
[assembly: AssemblyDescription("This application is a sample application.")]  
[assembly: AssemblyCopyright("Copyright © MyCompany 2009")]  

有没有办法做到以下几点:

Is there a way I can do the following:

[assembly: MyCustomAssemblyAttribute("Hello World! This is a custom attribute.")]

推荐答案

是的，你可以.我们做这种事情.

Yes you can. We do this kind of thing.

[AttributeUsage(AttributeTargets.Assembly)]
public class MyCustomAttribute : Attribute {
    string someText;
    public MyCustomAttribute() : this(string.Empty) {}
    public MyCustomAttribute(string txt) { someText = txt; }
    ...
}

阅读使用这种linq stmt.

To read use this kind of linq stmt.

var attributes = assembly
    .GetCustomAttributes(typeof(MyCustomAttribute), false)
    .Cast<MyCustomAttribute>();
