如何提取 ReSharper 模式中字符串的内容？

我遇到以下问题：

LINQ 成员表达式替换包含属性名称的硬编码字符串

// like this:
NotifyOfPropertyChange("MyProperty");
// becomes
NotifyOfPropertyChange(() => MyProperty);

我想用带有 ReSharper 模式的

。以下尝试不起作用：

NotifyOfPropertyChange("$prop$"); // ($prop$ is of type Identifier, results in parse error)
NotifyOfPropertyChange($prop$); // ($prop$ is of type Expression [System.String],  
                                // almost works, but without removing the quotes

替换模式始终相同：

NotifyOfPropertyChange(() => $prop$);

有什么想法吗？

I've got the following problem:

I want to replace a hardcoded string which contains a property name with a LINQ member expression

// like this:
NotifyOfPropertyChange("MyProperty");
// becomes
NotifyOfPropertyChange(() => MyProperty);

with a ReSharper pattern.

The following attempts didn't work:

NotifyOfPropertyChange("$prop$"); // ($prop$ is of type Identifier, results in parse error)
NotifyOfPropertyChange($prop$); // ($prop$ is of type Expression [System.String],  
                                // almost works, but without removing the quotes

The replace pattern was always the same:

NotifyOfPropertyChange(() => $prop$);

Any ideas?

我认为您不需要 R# 的结构搜索和替换（这很幸运，因为我认为在当前版本中它不能做到这一点）。 Visual Studio 的查找和替换正则表达式应该足够好：

Find What: 
NotifyPropertyChange\("{.*}"\)

( ) 被转义，这样它们就不会成为分组结构； { } 标记与其中的模式匹配，以使它们可用于替换表达式。

Replace with:
NotifyPropertyChange(() => \1)

这里的所有内容都是文字，除了 \1 之外，这意味着“第一个标记表达式”。

I don't think you need R#'s Structural Search and Replace here (which is fortunate, because I don't think in the present version it can do this). Visual Studio's Find and Replace regexes should be good enough:

Find What: 
NotifyPropertyChange\("{.*}"\)

The ( ) are escaped so that they dontg become a grouping construct; the { } tag whatever matches the pattern within to make them available to the replace expression

Replace with:
NotifyPropertyChange(() => \1)

Everything here is literal except \1, which means 'the first tagged expression'.

如果我正确理解你的意图，那么这可能会有所帮助。
前段时间我发现了这段代码（不记得最初是谁发布的）

public static string GetPropertyName<T>(Expression<Func<T>> propertyExpression)
    {
        return (propertyExpression.Body as MemberExpression).Member.Name;
    }

所以以下：

NotifyPropertyChange( () => MyProperty)

应该给出结果：

NotifyPropertyChange("MyProperty")

If I understand your intention correctly then this maybe will help.
Some time ago I found this piece of code ( can't remember who posted it originally)

public static string GetPropertyName<T>(Expression<Func<T>> propertyExpression)
    {
        return (propertyExpression.Body as MemberExpression).Member.Name;
    }

So the following:
