在Excel.Worksheet的工作表单元格中访问string？

如何访问Excel工作表中单元格中的string值？

string cellInfo = (string)w.Cells[3, 3]; 

我想在第三行，第三列，C3的string值

  Excel.Application excel = new Excel.Application(); Excel.Workbook workBook = excel.Workbooks.Open(string.Format(@"{0}\{1}", Directory.GetCurrentDirectory(), excelFilename), Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); List<Excel.Worksheet> result = excel.Worksheets.Cast<Excel.Worksheet>().Where(w => !exclude.Contains(w.Name)).ToList(); result.ForEach(w => { Excel.Range objRange = w.get_Range("C3", "C3"); string colLengthStr = objRange.Value2; }

有很多关于如何使用c＃从Excel中获取数据的答案。 但是你需要做类似的事情：

 Excel.Range objRange = (Excel.Range)objSheet.Cells[1,1]; strData = objRange.get_Value(Missing.Value).ToString(); 

如何使用C＃读取Excel文件的数据？

学习c＃Excel互操作的资源

要么

C＃Excel Interop

如何从C＃.NET自动化Excel

来自c＃.net的自动化Excel代码，包括读取/写入单元格：

 private void button1_Click(object sender, System.EventArgs e) { Excel.Application oXL; Excel._Workbook oWB; Excel._Worksheet oSheet; Excel.Range oRng; try { //Start Excel and get Application object. oXL = new Excel.Application(); oXL.Visible = true; //Get a new workbook. oWB = (Excel._Workbook)(oXL.Workbooks.Add( Missing.Value )); oSheet = (Excel._Worksheet)oWB.ActiveSheet; //Add table headers going cell by cell. oSheet.Cells[1, 1] = "First Name"; oSheet.Cells[1, 2] = "Last Name"; oSheet.Cells[1, 3] = "Full Name"; oSheet.Cells[1, 4] = "Salary"; //Format A1:D1 as bold, vertical alignment = center. oSheet.get_Range("A1", "D1").Font.Bold = true; oSheet.get_Range("A1", "D1").VerticalAlignment = Excel.XlVAlign.xlVAlignCenter; // Create an array to multiple values at once. string[,] saNames = new string[5,2]; saNames[ 0, 0] = "John"; saNames[ 0, 1] = "Smith"; saNames[ 1, 0] = "Tom"; saNames[ 1, 1] = "Brown"; saNames[ 2, 0] = "Sue"; saNames[ 2, 1] = "Thomas"; saNames[ 3, 0] = "Jane"; saNames[ 3, 1] = "Jones"; saNames[ 4, 0] = "Adam"; saNames[ 4, 1] = "Johnson"; //Fill A2:B6 with an array of values (First and Last Names). oSheet.get_Range("A2", "B6").Value2 = saNames; //Fill C2:C6 with a relative formula (=A2 & " " & B2). oRng = oSheet.get_Range("C2", "C6"); oRng.Formula = "=A2 & \" \" & B2"; //Fill D2:D6 with a formula(=RAND()*100000) and apply format. oRng = oSheet.get_Range("D2", "D6"); oRng.Formula = "=RAND()*100000"; oRng.NumberFormat = "$0.00"; //AutoFit columns A:D. oRng = oSheet.get_Range("A1", "D1"); oRng.EntireColumn.AutoFit(); //Manipulate a variable number of columns for Quarterly Sales Data.

根据您的编辑尝试以下内容：

 result.ForEach(w => { Excel.Range objRange = w.get_Range("C3", Missing.Value); string colLengthStr = objRange.Value2; }
