我想通过方法select从List中找到一个特定的值.

我的代码:

public class Calc
{
    public int IdCalc { get; set; }
    public double Result { get; set; }

        myC1.Result = 20.2;
        myC1.Number = 1;

        Calc myC2 = new Calc();
        myC2.IdCalc = 22;
        myC2.Result = 20.2;
        myC2.Number = 2;
        liCalc.Add(myC1);
        liCalc.Add(myC2);

        double getResult = ((Calc)(liCalc.Select(Calc => Calc.IdCalc = 22 && …
