是否有办法解决OLEDB连接(microsoft.ace.oledb.12.0'提供程序未在本地机器上注册)的问题,而不安装数据连接组件,同时读取excel文件
请建议。
尝试下面的代码
using System;
using System.IO;
using System.Reflection;
using NUnit.Framework;
using ExcelTools = Ms.Office;
using Excel = Microsoft.Office.Interop.Excel;
namespace Tests
{
[TestFixture]
public class ExcelSingle
{
[Test]
public void ProcessWorkbook()
{
string file = @"C:'Users'Chris'Desktop'TestSheet.xls";
Console.WriteLine(file);
Excel.Application excel = null;
Excel.Workbook wkb = null;
try
{
excel = new Excel.Application();
wkb = ExcelTools.OfficeUtil.OpenBook(excel, file);
Excel.Worksheet sheet = wkb.Sheets["Data"] as Excel.Worksheet;
Excel.Range range = null;
if (sheet != null)
range = sheet.get_Range("A1", Missing.Value);
string A1 = String.Empty;
if( range != null )
A1 = range.Text.ToString();
Console.WriteLine("A1 value: {0}", A1);
}
catch(Exception ex)
{
//if you need to handle stuff
Console.WriteLine(ex.Message);
}
finally
{
if (wkb != null)
ExcelTools.OfficeUtil.ReleaseRCM(wkb);
if (excel != null)
ExcelTools.OfficeUtil.ReleaseRCM(excel);
}
}
}
}
