Unity 5.5.2f1至5.6.1f1-插值字符串错误? [英] Unity 5.5.2f1 to 5.6.1f1 - interpolated strings error?

问题描述

我刚刚将我的Unity版本从5.5.2f1更新为5.6.1f1.突然出现错误:

I've just updated my Unity version from 5.5.2f1 to 5.6.1f1. Suddenly I get the error:

功能'内插字符串'不能使用，因为它不是一部分 C#4.0语言规范

Feature `interpolated strings' cannot be used because it is not part of the C# 4.0 language specification

下面的代码在更新之前效果很好.

The code below worked well before updating.

public class SensorData
{
    public int Timestamp { get; set; }
    public float Humidity { get; set; }
    public float Temp { get; set; }
    public int Light { get; set; }
    public int Button { get; set; }

    public override string ToString()
    {
        return $"{Timestamp}, {Humidity}, {Temp}, {Light}, {Button}";
    }
}

我不知道它是否仍然可以工作.

I don't have a clue if its supposed to still work.

推荐答案

似乎插值字符串在更新后仍然无法正常工作.为了仍然使用我上面提到的代码，我采用了旧方法.

It seems that interpolated strings are still not working after updating. To still use my above mentioned code, I did it the old way.

代替:

return $"{Timestamp}, {Humidity}, {Temp}, {Light}, {Button}";

我做到了:

return string.Format ("{Timestamp}, {Humidity}, {Temp}, {Light}, {Button}", Timestamp, Humidity, Temp, Light, Button);
