在C#中如何实现读取Excel中的sheet表中的任意行的数据,等待 直接用sheet的Cell(行,列)不可以吗? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 如果装的是officexp的话,可能需要用worksheet.get_Range("A1","A1").get_Value(); 那么有没有判断sheet表中有多少不为空的列的函数呢 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.
