這篇文章主要介紹了C# 操作Excel代碼總結(jié)，具有一定借鑒價值,需要的朋友可以參考下

本文分享了c#操作Excel的相關(guān)代碼，還是比較全面的，其實(shí)無外乎存取，增刪改查等操作，參考下。

具體代碼：

//引用Microsoft.Office.Interop.Excel.dll文件 
//添加using
using Microsoft.Office.Interop.Excel;
using Excel=Microsoft.Office.Interop.Excel;
 
//設(shè)置程序運(yùn)行語言
System.Globalization.CultureInfo CurrentCI = System.Threading.Thread.CurrentThread.CurrentCulture;
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
//創(chuàng)建Application
Excel.Application xlApp = new Excel.Application();
//設(shè)置是否顯示警告窗體
excelApp.DisplayAlerts = false;
//設(shè)置是否顯示Excel
excelApp.Visible = false;
//禁止刷新屏幕
excelApp.ScreenUpdating = false;
//根據(jù)路徑path打開
Excel.Workbook xlsWorkBook = excelApp.Workbooks.Open(path, System.Type.Missing, System.Type.Missing, System.Type.Missing,
System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing,
System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing);
//獲取Worksheet對象
Excel.Worksheet xlsWorkSheet = (Worksheet)xlsWorkBook.Worksheets["sales plan"];
 
***獲取最后一行、一列的兩種方法***
//獲取已用的范圍數(shù)據(jù)
int rowsCount = xlsWorkSheet.UsedRange.Rows.Count;
int colsCount = xlsWorkSheet.UsedRange.Columns.Count;
int rowsCount = xlsWorkSheet.get_Range("A65536", "A65536").get_End(Microsoft.Office.Interop.Excel.XlDirection.xlUp).Row;
int colsCount = xlsWorkSheet.get_Range("ZZ1", "ZZ1").get_End(Microsoft.Office.Interop.Excel.XlDirection.xlToLeft).Column;
 
***將Excel數(shù)據(jù)存入二維數(shù)組***
//rowsCount：最大行  colsCount：最大列
Microsoft.Office.Interop.Excel.Range c1 = (Microsoft.Office.Interop.Excel.Range)xlsWorkSheet.Cells[1, 1];
Microsoft.Office.Interop.Excel.Range c2 = (Microsoft.Office.Interop.Excel.Range)xlsWorkSheet.Cells[rowsCount, colsCount];
Range rng = (Microsoft.Office.Interop.Excel.Range)xlsWorkSheet.get_Range(c1, c2);
object[,] exceldata = (object[,])rng.get_Value(Microsoft.Office.Interop.Excel.XlRangeValueDataType.xlRangeValueDefault);
 
//在第一列的左邊插入一列
Excel.Range xlsColumns = (Excel.Range)xlsWorkSheet.Columns[1, System.Type.Missing];
xlsColumns.Insert(XlInsertShiftDirection.xlShiftToRight, Type.Missing);
//xlsSheetTemplateMajor_Meisai.Cells.get_Range(xlsSheetTemplateMajor_Meisai.Cells[1, 1], xlsSheetTemplateMajor_Meisai.Cells[65535, 1]).Insert(Type.Missing, Type.Missing);
 Excel.Range rng;
      rng = worksheet.get_Range("A:A", "A:A");
      rng.Insert(Excel.XlDirection.xlToRight, Excel.XlInsertFormatOrigin.xlFormatFromLeftOrAbove);
Excel.Range rng = (Microsoft.Office.Interop.Excel.Range)xlsWorkSheet.Columns[12, Type.Missing];
rng.Insert(XlInsertShiftDirection.xlShiftToRight, XlInsertFormatOrigin.xlFormatFromLeftOrAbove);
 
 
//刪除行
Range deleteRng = (Range)xlsWorkSheetSapExcel.Rows[2, System.Type.Missing];
deleteRng.Delete(Excel.XlDeleteShiftDirection.xlShiftUp);
 
//刪除一列數(shù)據(jù)
((Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[1, 11]).Select();
((Microsoft.Office.Interop.Excel.Range)xlWorkSheet.Cells[1, 11]).EntireColumn.Delete(0);
((Excel.Range)xlsSheetShareMajor_Meisai.Cells[1, 3]).EntireColumn.Delete (0);
       
//設(shè)置背景色為紅色
xlsWorkSheet.get_Range("A1", "A1").Interior.ColorIndex = 3;
 
//設(shè)置Format屬性  屬性值可以通過在vba中錄宏得到

//通過行、列的索引獲取值
string f = Convert.ToString(xlsSheetShareMajor_Meisai.get_Range(xlsSheetShareMajor_Meisai.Cells[2, 1], xlsSheetShareMajor_Meisai.Cells[2,1]).Value2);
 
//篩選
