C＃传递值从一个方法到另一个

本文介绍了C＃传递值从一个方法到另一个的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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：

有 SingleColumn 的收益的结果并补充说，作为参数传递给 SMA

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:

have SingleColumn return results and add that as a parameter to SMA

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.
