从基础实体中查找属性的使用 [英] Find usage of property from base entity

问题描述

我试图在属性属于基类的类中查找属性的用法.这是一个令牌示例:

I'm trying to find the usage of a property in a class where the property belongs to a base class. Here is a token example:

class Program
{
    class Item
    {
        public DateTime DeletedStamp { get; set; }

        public decimal Price { get; set; }
    }

    class Book : Item
    {
        public string Title { get; set; }

        public string Author { get; set; }
    }

    class Bicycle : Item
    {
        public string Type { get; set; }

        public string Producer { get; set; }
    }

    static void Main(string[] args)
    {
        var book = new Book()
        {
            Title = "Atlas Shrugged",
            Author = "Ayn Rand",
            Price = 2.99M
        };

        var bicycle = new Bicycle()
        {
            Type = "Mountain bike",
            Price = 499.99M,
            Producer = "Biker Ben",
            DeletedStamp = DateTime.Now
        };

        Console.WriteLine(book.Title);
        Console.WriteLine(book.Price);

        Console.WriteLine(bicycle.Price);
        Console.WriteLine(bicycle.DeletedStamp);
    }
}

如果我只想在自行车项目中找到 Price 的用法，我发现我不走运.我在 Visual Studio 2013 中使用 re-sharper，Find Usage 找到 Price 的所有用法，包括 Book 中的用法.这是一个小示例，但由于基类在许多其他类中使用，因此无法跟踪使用情况.

If I want to find the usage of Price in only bicycle items I find that I'm out of luck. I'm using re-sharper in Visual Studio 2013 and Find Usage finds all usage of Price including the usage in Book. This is a small example but with a base class used in a lot of other classes it becomes impossible to track down usages.

我正在寻找任何提示、技巧、扩展或魔法来解决这个困境.

I'm looking for any tip, trick, extension or magic spell to solve this dilemma.

推荐答案

对于这种情况，ReSharper 的 SRP (Search and Replace with Pattern) 非常有用.

For this case is very usefull the ReSharper's SRP (Search and Replace with Pattern).

Menu Resharper->Find->Search with Pattern...

Menu Resharper->Find->Search with Pattern...

在这里定义以下模式:

$Item$.Price

仅用于写入用途:

$Item$.Price = $exp$;

或仅用于读取用途:

$exp$ = $Item$.Price

其中 $Item$ 应该是表达式占位符，选择类型自行车"并且不要忘记选中正是这种类型".

where $Item$ should be an expression placeholder, select the type "Bicycle" and don't forget to check "Exactly this type".

$exp$ 可以保持未定义

The $exp$ can stay undefined
