工具使用
- Spire.XLS for .NET 8.0
下載安裝該類庫後,註意在程序中添加引用Spire.Xls.dll(dll文件可在安裝路徑下的Bin文件夾中獲取)
代碼示例(供參考)【示例1】創建Excel公式
C#
using Spire.Xls; namespace CreateFormula { class Program { static void Main(string[] args) { //新建一個工作簿,獲取第一個工作表 Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0]; //初始化currentRow、currentFormula int currentColumn = 1; int currentRow = 1; string currentFormula = string.Empty; //設置1、2列列寬 sheet.SetColumnWidth(1, 20); sheet.SetColumnWidth(2, 12); //寫入測試數據 sheet.Range[currentColumn, 1].Value = "測試數據:"; sheet.Range[currentColumn, 2].NumberValue = 10; sheet.Range[currentColumn, 3].NumberValue = 20; sheet.Range[currentColumn, 4].NumberValue = 30; sheet.Range[currentColumn, 5].NumberValue = 40; sheet.Range[currentColumn, 6].NumberValue = 50; //寫入文本並設置區域格式 currentRow += 2; sheet.Range[currentRow, 1].Value = "公式"; sheet.Range[currentRow, 2].Value = "結果"; CellRange range = sheet.Range[currentRow, 1, currentRow, 2]; range.Style.Font.IsBold = true; range.Style.KnownColor = ExcelColors.LightGreen1; range.Style.FillPattern = ExcelPatternType.Solid; range.Style.Borders[BordersLineType.EdgeBottom].LineStyle = LineStyleType.Medium; //算術運算 currentFormula = "=1/2+3*4"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //日期函數 currentFormula = "=Today()"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; sheet.Range[currentRow, 2].Style.NumberFormat = "YYYY/MM/DD"; //時間函數 currentFormula = "=NOW()"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; sheet.Range[currentRow, 2].Style.NumberFormat = "H:MM AM/PM"; //IF邏輯函數 currentFormula = "=IF(B1=5,\"Yes\",\"No\")"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //PI函數 currentFormula = "=PI()"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //三角函數 currentFormula = "=SIN(PI()/6)"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //計數函數 currentFormula = "=Count(B1:F1)"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //求最大值函數 currentFormula = "=MAX(B1:F1)"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //平均值函數 currentFormula = "=AVERAGE(B1:F1)"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //求和函數 currentFormula = "=SUM(B1:F1)"; sheet.Range[++currentRow, 1].Text = currentFormula; sheet.Range[currentRow, 2].Formula = currentFormula; //保存文檔並打開 workbook.SaveToFile("Excel公式.xlsx", FileFormat.Version2013); System.Diagnostics.Process.Start("Excel公式.xlsx"); } } }
公式創建結果(如下圖):
【示例2】讀取Excel公式
C#
using Spire.Xls; using System; namespace ReadFormula { class Program { static void Main(string[] args) { //實例化一個Workbook Workbook workbook = new Workbook(); //加載測試文檔 workbook.LoadFromFile("test.xlsx"); //獲取第一個工作表 Worksheet sheet = workbook.Worksheets[0]; //遍歷[B1:B13]的單元格 foreach (var cell in sheet.Range["B1:B13"]) { //判斷是否含有公式 if (cell.HasFormula) { //輸出含有公式的單元格及公式 string certainCell = String.Format("Cell[{0},{1}]", cell.Row, cell.Column); Console.WriteLine(certainCell + " 含有公式: " + cell.Formula); } } Console.ReadLine(); } } }
公式讀取結果(如下圖)
