字符串的平均，最大，最小，总和? [英] Avg,max,min,sum from string?

问题描述

你好，我得到了一个字符串数组，它们是我自己使用的格式为 H:M:S:MS

Hello i got array of string, and they are durations made by myself in format H:M:S:MS

示例字符串:

0:0:4:410
0:0:1:425
0:0:1:802
0:0:1:509
0:0:1:674
0:0:1:628
0:0:2:76

我怎么在阵列列表中这些项目的总和/平均值/最小值/最大值?

Arraylist名称为 arrayLL .

Arraylist name is arrayLL.

我是C#的新手，所以希望有人向我展示如何使用字符串.

I'm new in c# so hope someone will show me how to work with strings.

添加到数组的函数是:

if (Session["DT"].ToString() != "")
{
    TimeSpan ts = ((DateTime)Session["DT2"]).Subtract((DateTime)Session["DT"]);

    Session["TimeL"] = ts.Hours.ToString() + ":" 
                            + ts.Minutes.ToString() + ":"
                            + ts.Seconds.ToString() + ":" 
                            + ts.Milliseconds.ToString();
}

推荐答案

假设数字表示小时，分钟，秒和毫秒，则可以尝试以下操作:

Assuming the numbers represent hours, minutes, seconds, and milliseconds you can try the following:

// Empty list you will populate:
List<int> durationsInMilliseconds = new List<int>();

// Loop through your existing data, and calculate all
// durations into milliseconds:
foreach (string word in yourDurationArray)
{
    string[] values = s.Split(':');
    int hoursAsMilliseconds = Integer.parse(values[0]) * 60 * 60 * 1000;
    int minutesAsMilliseconds = Integer.parse(values[1]) * 60 * 1000;
    int secondsAsMilliseconds = Integer.parse(values[2]) * 1000;

    int sumDurationAsMilliseconds = hoursAsMilliseconds + 
                                    minutesAsMilliseconds + 
                                    secondsAsMilliseconds + 
                                    Integer.parse(values[3]);

    durationsInMilliseconds.add(sumDurationAsMilliseconds);
}

现在，您应该具有整数类型( durationsInMilliseconds )的列表，其中包含可比较的单一格式的数字.这样，您应该能够进行所需的任何计算.

Now you should have a list of type Integer (durationsInMilliseconds) which contains the numbers in a single comparable format. With this, you should be able to do whichever calculations you need.

(PS:如果您需要与原始输入数据相同格式的结果，则必须添加一个操作，以从MS向后计算小时，分钟和秒.)
