求Double[]平均值

Question

这是在数据库鼠标放上去显示的值。复制出来就是这样的里面有好几十个值，都是0.XXX，如果求他们的平均值啊？我要做的是，就是要在这里判断这个值是否大于我在前台页面设置的值，如果超标了，我就得入历史库

Answer 1

void Main()
{

double[] d={0.3540,0.1801,0.1862,0.1770};
double d1=d.Average();
Console.Write(d1);
}/*
0.224325*/

Answer 2

double[] HarAplCount = Convert.ToDouble(sHarApl);
                double AvgHarApl = HarAplCount.Average();
                double DHarApl = 0.4; //定义值
                if (AvgHarApl > DHarApl) //判断是否超标参考值
                {
                    NJCHECDataAccess.GetDataset(sqlHis); //执行sql语句将此时波形存入数据库
                }

Answer 3

 double dNum=0.00;
        string strDouble="0.11, 0.22, 0.33,";
        string[] strDoubles = strDouble.Split(',');
        string strLength = strDoubles.Length.ToString();
        int intLength = strDoubles.Length;
        for (int i = 0; i < intLength; i++)
        {
            if (strDoubles[i].ToString() != "")
            {
                string strName = strDoubles[i].ToString();
                dNum += double.Parse(strDoubles[i].ToString().Trim());
            }
            
        }
        double dAvg = dNum / (intLength - 1);//减掉最后一个
        lbl1.InnerText = dAvg.ToString();

Answer 4

                double [] HarAplCount = sHarApl;
                double AvgHarApl = HarAplCount.Average();
                double DHarApl = 0.4; //定义值
                if (AvgHarApl > DHarApl) //判断是否超标参考值
                {
                    NJCHECDataAccess.GetDataset(sqlHis); //执行sql语句将此时波形存入数据库
                }后面  sHarApl 是个string 怎么转成double[] 啊！

Answer 5

void Main()
{
string sHarApl="0.3540,0.1801,0.1862,0.1770"; 
List<double>list=new List<double>(); 
sHarApl.Split(',').ToList().ForEach(s=>list.Add(Convert.ToDouble(s)));
Console.WriteLine(list.Average());
}/*
0.224325
*/
