C＃传递值从一个方法到另一个 [英] C# passing values from one method to another

问题描述

我得到的结果错误代码。下面的代码。我基本上想从 SingleColumn 方法的数据集，并在 SMA 方法使用它。但我在目前的情况下不存在得到结果DEOS。

 的静态公共无效SMA（）
 {
双击[] = closePrice results.ToArray（）; 
  

下面你可以看到 SingleColumn 和零件的 SMA 代码。

 ＃地区的单立柱
 //静态公共双重效果; 
静态公共无效SingleColumn（IEnumerable的<串>可疑交易报告，INT highNum）
 {
＃地区泻数据列
 Console.WriteLine（单列查询：）; 
 VAR columnQuery =从可疑交易报告
线让元素= line.Split（''）
选择Convert.ToDouble（元素[highNum]）; 
变种结果= columnQuery.ToList（）; 
双[] = closePrice results.ToArray（）; 
 #endregion 
 
＃地区的最大值，最小值，平均值
双平均= results.Average（）; 
双最大值= results.Max（）; 
双分钟= results.Min（）; 
 Console.WriteLine（高：{0}：低：{1}：平均：{2：0.00}，最大值，最小值，平均值）; 
 #endregion 
} 
 
＃地区的战略码SMA 
静态公共无效SMA（）
 {
双[] = closePrice结果。 ToArray的（）; 
 INT TOTAL_PERIODS = closePrice.Length; 
双[] =输出新的双[TOTAL_PERIODS] 
 INT开始; 
 INT长度; 
 
的for（int i = 0; I< closePrice.Length-TOTAL_PERIODS;我++）//不得不从-1改为-TOTAL_PERIODS 
 {
 closePrice [I] =（双）我; 
} 
 
 TicTacTec.TA.Library.Core.RetCode RETCODE = Core.Sma（0，closePrice.Length-1，closePrice，PERIODS_AVERAGE，开始出来，出来的长度，输出）; 
  

解决方案

您有一些选择：

1. 有 SingleColumn 的收益的结果并补充说，作为参数传递给 SMA


2. 请结果类的字段，以便它是共享的。

选项1是更清洁，因为它迫使主叫方呼叫 SingleColumn 第一（或拿出自己的列表）

 静态公网双[] SingleColumn （IEnumerable的<串GT;可疑交易报告，INT highNum）
 {
：
返回closePrice; 
} 
 
＃地区的战略码SMA 
静态公共无效SMA（双[] closePrice）
 {
 INT TOTAL_PERIODS = closePrice.Length; 
双[] =输出新的双[TOTAL_PERIODS] 
：
} 
  

请注意，我是从改变了你的输出/输入结果到 closePrice ，因为它只是将其转换为一个List和背部。这只是清洁离开它作为一个双[] 。您也可以只使用清理代码位的的ToArray 而不是使用了ToList 和然后 的ToArray 。

I am getting an error code in the result. code below. I am basically trying to get a data set from SingleColumn method and use it in SMA method. But I am getting results deos not exist in current context.

static public void SMA()
{
    double[] closePrice = results.ToArray(); 

Below you can see the SingleColumn and part of SMA code.

#region Single Column
//static public double results;
static public void SingleColumn(IEnumerable<string> strs, int highNum)
{
    #region spilt data to columns
    Console.WriteLine("Single Column Query:");
    var columnQuery = from line in strs 
                      let elements = line.Split(',')
                      select Convert.ToDouble(elements[highNum]); 
    var results = columnQuery.ToList();
    double[] closePrice = results.ToArray();
    #endregion

    #region max, min, avg
    double average = results.Average();
    double max = results.Max();
    double min = results.Min();
    Console.WriteLine("High: {0}: Low: {1}: Average: {2:0.00}", max, min, average);
    #endregion
}

    #region Strategy Code SMA
static public void SMA()
{
    double[] closePrice = results.ToArray(); 
    int TOTAL_PERIODS = closePrice.Length;
    double[] output = new double[TOTAL_PERIODS];
    int begin;
    int length;

    for (int i = 0; i < closePrice.Length-TOTAL_PERIODS; i++) //had to change from -1 to -TOTAL_PERIODS
    {
        closePrice[i] = (double)i;
    }

    TicTacTec.TA.Library.Core.RetCode retCode = Core.Sma(0, closePrice.Length-1, closePrice, PERIODS_AVERAGE, out begin, out length, output);

解决方案

You have some options:

1. have SingleColumn return results and add that as a parameter to SMA
2. make results a field of the class so it is shared.

Option 1. is cleaner since it forces callers to call SingleColumn first (or come up with a list on their own)

    static public double[] SingleColumn(IEnumerable<string> strs, int highNum)
    {
        ...
        return closePrice;
    }

        #region Strategy Code SMA
    static public void SMA(double[] closePrice)
    {
        int TOTAL_PERIODS = closePrice.Length;
        double[] output = new double[TOTAL_PERIODS];
        ...
    }   

Note that I changed your output/input from result to closePrice since it was just converting it to a List and back. It's cleaner just to leave it as a double[]. You can also clean up the code a bit by just using ToArray instead of using ToList and then ToArray.
