如何在excel中找到下一个空行并将数据导出到该行？

本文介绍了如何在excel中找到下一个空行并将数据导出到该行？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我当前可以将每个textBox导出到第2行的单个单元格。但是它只能写入覆盖先前数据的位置。我试图弄清楚如何在每次提交后确定下一个可用的空白行。下面是我当前只写入第2行的代码。 Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet; Microsoft.Office.Interop.Excel.Sheets xlBigSheet; 对象misValue; String myPath; private void Button1_Click（object sender，EventArgs e） { string myPath = @C：\\Users\\N0m4d \\Desktop \\ \\\Longhouse\\database.xlsx; //这必须是完整路径。 FileInfo fi = new FileInfo（myPath）; if（！fi.Exists） { Console.Out.WriteLine（file is not exists！）; } else { var excelApp = new Microsoft.Office.Interop.Excel.Application（）; var workbook = excelApp.Workbooks.Open（myPath）; 工作表工作表= workbook.ActiveSheet作为工作表; 范围range1 = worksheet.Cells [2,1]作为Range; range1.Value2 = textBox1.Text; 范围range2 = worksheet.Cells [2,2]作为Range; range2.Value2 = textBox2.Text; 范围range3 = worksheet.Cells [2,3]作为Range; range3.Value2 = textBox3.Text; 范围range4 = worksheet.Cells [2,4]作为Range; range4.Value2 = textBox4.Text; 范围range5 = worksheet.Cells [2,5]作为Range; range5.Value2 = textBox5.Text; 范围range6 = worksheet.Cells [2,6]作为Range; range6.Value2 = textBox6.Text; excelApp.Visible = true; workbook.Save（）; //workbook.Close（）; textBox1.Text = string.Empty; textBox2.Text = string.Empty; textBox3.Text = string.Empty; textBox4.Text = string.Empty; textBox5.Text = string.Empty; textBox6.Text = string.Empty; xlWorkSheet =（Microsoft.Office.Interop.Excel.Worksheet）xlBigSheet.get_Item（Sheet1）; Microsoft.Office.Interop.Excel.Range last = xlWorkSheet.Cells.SpecialCells（Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeLastCell，Type.Missing）; int lastUsedRow = last.Row; getData（lastUsedRow + 1）; } } private void getData（int lastRow_） { lastRow_ = xlWorkSheet.Cells.Find（ *， xlWorkSheet.Cells [1,1]， misValue， Microsoft.Office.Interop.Excel.XlLookAt.xlPart， Microsoft.Office.Interop.Excel .XlSearchOrder.xlByRows， Microsoft.Office.Interop.Excel.XlSearchDirection.xlPrevious， misValue， misValue， misValue）.Row + 1; } 我尝试过： 尝试了谷歌的多项建议，但我并不完全了解如何根据我的需要修改它们。解决方案 I can currently currently export each textBox to an individual cell on row 2. However it can only write to that location which overwrites the previous data. I am trying to figure out how to make it identify the next available blank row after every submission. Below is my current code that only write to row 2. Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet; Microsoft.Office.Interop.Excel.Sheets xlBigSheet; object misValue; String myPath; private void Button1_Click(object sender, EventArgs e) { string myPath = @"C:\\Users\\N0m4d\\Desktop\\Longhouse\\database.xlsx"; // this must be full path. FileInfo fi = new FileInfo(myPath); if (!fi.Exists) { Console.Out.WriteLine("file doesn't exists!"); } else { var excelApp = new Microsoft.Office.Interop.Excel.Application(); var workbook = excelApp.Workbooks.Open(myPath); Worksheet worksheet = workbook.ActiveSheet as Worksheet; Range range1 = worksheet.Cells[2, 1] as Range; range1.Value2 = textBox1.Text; Range range2 = worksheet.Cells[2, 2] as Range; range2.Value2 = textBox2.Text; Range range3 = worksheet.Cells[2, 3] as Range; range3.Value2 = textBox3.Text; Range range4 = worksheet.Cells[2, 4] as Range; range4.Value2 = textBox4.Text; Range range5 = worksheet.Cells[2, 5] as Range; range5.Value2 = textBox5.Text; Range range6 = worksheet.Cells[2, 6] as Range; range6.Value2 = textBox6.Text; excelApp.Visible = true; workbook.Save(); //workbook.Close(); textBox1.Text = string.Empty; textBox2.Text = string.Empty; textBox3.Text = string.Empty; textBox4.Text = string.Empty; textBox5.Text = string.Empty; textBox6.Text = string.Empty; xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlBigSheet.get_Item("Sheet1"); Microsoft.Office.Interop.Excel.Range last = xlWorkSheet.Cells.SpecialCells(Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeLastCell, Type.Missing); int lastUsedRow = last.Row; getData(lastUsedRow + 1); } } private void getData(int lastRow_) { lastRow_ = xlWorkSheet.Cells.Find( "*", xlWorkSheet.Cells[1, 1], misValue, Microsoft.Office.Interop.Excel.XlLookAt.xlPart, Microsoft.Office.Interop.Excel.XlSearchOrder.xlByRows, Microsoft.Office.Interop.Excel.XlSearchDirection.xlPrevious, misValue, misValue, misValue).Row + 1; }What I have tried:Tried multiple suggestions from google but I do not full understand how to modify them to fit my needs. 解决方案 这篇关于如何在excel中找到下一个空行并将数据导出到该行？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
