问题描述
我已经看了很多遍,但无法弄清楚.您如何汇总BigIntegers列表?
I've looked all over but can't figure this out. How do you sum a list of BigIntegers?
Using System.Numerics;
Using System.Linq;
List<BigInteger> bigInts = new List<BigInteger>();
BigInteger sum = bigInts.Sum(); // doesn't work
BigInteger sum = bigInts.Sum<BigInteger>(); // doesn't work
BigInteger sum = bigInts.Sum(x => x); // doesn't work
您必须这样做吗?
BigInteger sum = new BigInteger(0);
foreach(BigInteger bigint in bigInts)
sum += bigint;
推荐答案
Aggregate 函数是Sum的通用版本:
Aggregate function is more general version of Sum:
var bigInts = new List<System.Numerics.BigInteger>();
bigInts.Add(new System.Numerics.BigInteger(1));
var result = bigInts.Aggregate((currentSum, item)=> currentSum + item));
