Question

我只需要向特定类或特定方法添加日志记录。阅读文档 here 和 here 我找不到达到目标的方法。

下面列出的是我的测试用例。

namespace ClassLibrary1.C1
{
    public class Class1
    {
        public int Method1()
        {
            return 42;
        }    
    } 
}

namespace ClassLibrary1.C2
{
    public class Class2
    {
        public int Method1()
        {
            return 42 * 2;
        }     
    }

    public class Class3
    {
        public int Method1()
        {
            return 42 * 2;
        }     

        public int Method2()
        {
            return 42 * 3;
        }     

    }
}

AssemblyInfo 内容

using PostSharp.Patterns.Diagnostics;
using PostSharp.Extensibility;

[assembly: Log(AttributePriority = 1, AttributeExclude = true, AttributeTargetTypes = "ClassLibrary1.*")]
[assembly: Log(AttributePriority = 2, AttributeExclude = false, AttributeTargetTypes = "ClassLibrary1.C2*")]

通过这种方式，我可以从日志中排除整个 Class1，但这只是因为它属于不同的命名空间。

如何仅将 Class3.Method2() 包含到日志中？

Answer 1

我使用 AttributeTargetMembers 发布我的解决方案

using PostSharp.Patterns.Diagnostics;
using PostSharp.Extensibility;

[assembly: Log(AttributePriority = 1, AttributeExclude = true, AttributeTargetMembers="Method1")]    
[assembly: Log(AttributePriority = 2, AttributeExclude = false, AttributeTargetMembers="Method2")]
[assembly: Log(AttributePriority = 3, AttributeExclude = true, AttributeTargetTypes = "ClassLibrary1.C1*")]
[assembly: Log(AttributePriority = 4, AttributeExclude = true, AttributeTargetTypes = "ClassLibrary1.C2.Class2")]

Answer 2

@ilCosmico 的回答是正确的。包含特定成员的另一种方法是向成员声明添加 [Log] 属性。例如：

...

namespace ClassLibrary1.C2
{
    ...

    public class Class3
    {
        ...

        [Log]
        public int Method2()
        {
            return 42 * 3;
        }     

    }
}

PostSharp：仅包含某些类或某些方法
