這篇文章主要介紹了C#實現(xiàn)導(dǎo)入CSV文件到Excel工作簿的方法,涉及C#針對office組件的相關(guān)操作技巧,需要的朋友可以參考下

本文實例講述了C#實現(xiàn)導(dǎo)入CSV文件到Excel工作簿的方法。分享給大家供大家參考。具體如下：

你必須在項目中添加對 Microsoft.Office.Core 的引用：from the .NET tab of the Visual Studio Add Reference dialog box, and the Microsoft Excel 12.0 Object Library (you can use 14.0 if you want, too, but nothing lower).

C#代碼如下：

using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Core;
/// <summary>
/// Takes a CSV file and sucks it into the specified worksheet of this workbook at the specified range
/// </summary>
/// <param name="importFileName">Specifies the full path to the .CSV file to import</param>
/// <param name="destinationSheet">Excel.Worksheet object corresponding to the destination worksheet.</param>
/// <param name="destinationRange">Excel.Range object specifying the destination cell(s)</param>
/// <param name="columnDataTypes">Column data type specifier array. For the QueryTable.TextFileColumnDataTypes property.</param>
/// <param name="autoFitColumns">Specifies whether to do an AutoFit on all imported columns.</param>
public void ImportCSV(string importFileName, Excel.Worksheet destinationSheet,
  Excel.Range destinationRange, int[] columnDataTypes, bool autoFitColumns)
{
  destinationSheet.QueryTables.Add(
    "TEXT;" + Path.GetFullPath(importFileName),
  destinationRange, Type.Missing);
  destinationSheet.QueryTables[1].Name = Path.GetFileNameWithoutExtension(importFileName);
  destinationSheet.QueryTables[1].FieldNames = true;
  destinationSheet.QueryTables[1].RowNumbers = false;
  destinationSheet.QueryTables[1].FillAdjacentFormulas = false;
  destinationSheet.QueryTables[1].PreserveFormatting = true;
  destinationSheet.QueryTables[1].RefreshOnFileOpen = false;
  destinationSheet.QueryTables[1].RefreshStyle = XlCellInsertionMode.xlInsertDeleteCells;
  destinationSheet.QueryTables[1].SavePassword = false;
  destinationSheet.QueryTables[1].SaveData = true;
  destinationSheet.QueryTables[1].AdjustColumnWidth = true;
  destinationSheet.QueryTables[1].RefreshPeriod = 0;
  destinationSheet.QueryTables[1].TextFilePromptOnRefresh = false;
  destinationSheet.QueryTables[1].TextFilePlatform = 437;
  destinationSheet.QueryTables[1].TextFileStartRow = 1;
  destinationSheet.QueryTables[1].TextFileParseType = XlTextParsingType.xlDelimited;
  destinationSheet.QueryTables[1].TextFileTextQualifier = XlTextQualifier.xlTextQualifierDoubleQuote;
  destinationSheet.QueryTables[1].TextFileConsecutiveDelimiter = false;
  destinationSheet.QueryTables[1].TextFileTabDelimiter = false;
  destinationSheet.QueryTables[1].TextFileSemicolonDelimiter = false;
  destinationSheet.QueryTables[1].TextFileCommaDelimiter = true;
  destinationSheet.QueryTables[1].TextFileSpaceDelimiter = false;
  destinationSheet.QueryTables[1].TextFileColumnDataTypes = columnDataTypes;
  Logger.GetInstance().WriteLog("Importing data...");
  destinationSheet.QueryTables[1].Refresh(false);
  if (autoFitColumns==true)
    destinationSheet.QueryTables[1].Destination.EntireColumn.AutoFit();
  // cleanup
  this.ActiveSheet.QueryTables[1].Delete();
}

使用方法如下：

myOwnWorkbookClass.ImportCSV(
   @"C:\MyStuff\MyFile.CSV",
   (Excel.Worksheet)(MyWorkbook.Worksheets[1]),
   (Excel.Range)(((Excel.Worksheet)MyWorkbook.Worksheets[1]).get_Range("$A$7")),
   new int[] { 2, 2, 2, 2, 2 }, true);

希望本文所述對大家的C#程序設(shè)計有所幫助。
