我创建了一个用于线程同步的类,我想将其应用于方法,类,属性等,而无需遍历并将代码插入每个函数,类等中。这是当前必须执行的示例:

public class NotWhatIWantExample
{
    LockingClass locker;
    public int function()
    {
        locker.EnterWriteBlock();
        if (condition)
        {
            locker.LeaveWriteBlock();
            return 0;
        }
        locker.LeaveWriteBlock();
        return 1;
    }
}


接下来是如果可能的话我想做的两个例子

范例2:

// [LockingClassAttribute(LockingClassAttribute.WriteBlock)]
// Not Declared But Added Since Attribute Is Applied On A Method
public class WhatIWantExample
{
    //LockingClass locker; Included In The Attribute

    [LockingClassAttribute(LockingClassAttribute.WriteBlock)]public int function()
    {
        if (condition)
            return 0;
    }
}


范例3:

[LockingClassAttribute(LockingClassAttribute.ReadWriteBlock)]
public class WhatIWantExample
{
    //LockingClass locker; Included In The Attribute

    //Function Would Override LockingClassAttribute.ReadWriteBlock
    [LockingClassAttribute(LockingClassAttribute.WriteBlock)]public int function()
    {
        if (condition)
            return 0;
        return 1;
    }
    //Would Inherit [LockingClassAttribute(LockingClassAttribute.ReadWriteBlock)]
    public int function2()
    {
        if (condition)
            return 0;
        return 1;
    }
}


这可能吗?

最佳答案

这是aspect orientated programming的示例。它在C#中不是直接可用的,但是您可以使用PostSharp来进行此类操作。

看一下OnMethodBoundaryAspect类,该类使您可以在方法运行之前和完成之后运行代码。
