如何在C#中从Excel读取数据

或者直接在这里下载DLL

using IronXL; using System; using System.Linq; // Supported for XLSX, XLS, XLSM, XLTX, CSV and TSV WorkBook workBook = WorkBook.Load("sample.xlsx"); // Select worksheet at index 0 WorkSheet workSheet = workBook.WorkSheets[0]; // Get any existing worksheet WorkSheet firstSheet = workBook.DefaultWorkSheet; // Select a cell and return the converted value int cellValue = workSheet["A2"].IntValue; // Read from ranges of cells elegantly. foreach (var cell in workSheet["A2:A10"]) { Console.WriteLine("Cell {0} has value '{1}'", cell.AddressString, cell.Text); } // Calculate aggregate values such as Min, Max and Sum decimal sum = workSheet["A2:A10"].Sum(); // Linq compatible decimal max = workSheet["A2:A10"].Max(c => c.DecimalValue);
