我怎么称呼我的价值？ [英] How do I call my value?

问题描述

我需要访问underw值，例如open，low等。

在主程序program.cs中我想引用这个值。

它是什么错了？



我尝试过：

I need acess to the beloww value for example open, low so on.
In main program program.cs I want to reference to this value.
What it's wrong?

What I have tried:

<pre lang="c#">

/* Data.cs*/

 public class TimeSeries
        {
            public TimeSeries()
            { }
            [JsonProperty(PropertyName = "1. open")]
            public string Open { get; set; }
            [JsonProperty(PropertyName = "2. high")]
            public string High { get; set; }
            [JsonProperty(PropertyName = "3. low")]
            public string Low { get; set; }
            [JsonProperty(PropertyName = "4. close")]
            public string Close { get; set; }
            [JsonProperty(PropertyName = "5. volume")]
            public string Volume { get; set; }
        }

        public string Acess()   // here it is red underline
        {
            this.High = H;
            return this.High;
        }
/*Program.cs in main program I'd like to something like this high-low*/

推荐答案

简单：它不在课堂内：

Simple: it's not inside a class:

 public class TimeSeries
        {
...
        }

        public string Acess()   // here it is red underline
        {
            this.High = H;
            return this.High;
        }

C＃中的所有东西都必须属于一个类！



尝试移动紧密的大括号：

Everything in C# has to be part of a class!

Try just moving the close curly bracket:

public class TimeSeries
       {
           public TimeSeries()
           { }
           [JsonProperty(PropertyName = "1. open")]
           public string Open { get; set; }
           [JsonProperty(PropertyName = "2. high")]
           public string High { get; set; }
           [JsonProperty(PropertyName = "3. low")]
           public string Low { get; set; }
           [JsonProperty(PropertyName = "4. close")]
           public string Close { get; set; }
           [JsonProperty(PropertyName = "5. volume")]
           public string Volume { get; set; }

           public string Acess()
           {
               this.High = H;
               return this.High;
           }
       }

读取错误窗格上的错误消息，或者将鼠标悬停在红线上会告诉你这个...

Reading the error message on the Errors pane, or by hovering over the red line would have told you this...
