如何添加记录列表 [英] How do I add a list of records

问题描述

大家好，



我需要创建一个方法来在列表中添加条目列表（例如，我需要添加列表的所有收入）得到一个总额）



列表创建和打印如下，我需要在底部添加所有收入的总额：

Hi Guys,

I need to create a method to add a list of entries in a list (eg. I need to add all the incomes of a list to get a total)

List creation and print below, I need to add the total of all income at the bottom:

List<TaxRecord> taxrecords = new List<TaxRecord>()
        {
            new TaxRecord(53664,"John Smith","34 Johns St Sydney",true,6364664.99),
            new TaxRecord(53667,"Steve Henry","38 Victoria Rd Bulli",false,900.88),
            new TaxRecord(53656,"James Tee","65 True St Woonona",true,15678.00)
        };
        foreach (TaxRecord t in taxrecords)
        {
            t.Print();

        }

推荐答案

double total = taxrecords.Sum(item => item.Amount);

假设你的TaxRecord类有一个名为income的属性，类型为double，然后尝试下面的代码，它将总结列表中的所有收入。

Suppose that your TaxRecord class has a property named income which is of type double then try the below code which will sum up all the incomes within the list.

double total = 0;
foreach (TaxRecord t in taxrecords)
{
    total += t.income;
}
