如何使用 IronXL 在 C# 中使用数学函数进行Excel数据提取和分析

using IronXL;
using System.Linq;

WorkBook workBook = WorkBook.Load("sample.xls");
WorkSheet workSheet = workBook.WorkSheets.First();

// Get range from worksheet
var range = workSheet["A1:A8"];

// Calculate the sum of numeric cells within the range
decimal sum = range.Sum();

// Calculate the average value of numeric cells within the range
decimal avg = range.Avg();

// Identify the maximum value among numeric cells within the range
decimal max = range.Max();

// Identify the minimum value among numeric cells within the range
decimal min = range.Min();
