基于ReSharper将属性更改为表达式身体会导致错误？

Question

one of my properties looks like this:

public string Name
{
 get{ return _name; }
 set { _name = value; }
}

but ReSharper is advising me to change it to:

public string Name
{
 get => _name;
 set => _name = value;
}

if I refactor like that then compilation throws error Is it not possible to have expression body in a Property ?

Answer 1

Before c# 6 you couldn't use expression bodies in properties and had to write something like this.

public string FullName
{
    get { return string.Format("{0} {1}", FirstName, LastName); }
}

In c# 6 you can create readonly experession bodies.

public string FullName => $"{FirstName} {LastName}";

In c# 7 you got expression bodies for members like you showed.

public string Name
{
    get => _name;
    set => _name = value;
}

Answer 2

If you want ReSharper not to adapt this behavior you can change it:

Resharper > Options > Code Editing > C# > Code Style

and change the following property:

Code body > Properties, indexers and events from Expression body to Accessors with block body

If you just want to disable the suggestion change the notification state of the property mentioned above.
