有朋友問道：

[c-sharp] view plain copy print ?

1. public
    ArrayList ExcelSheetName(string filepath)  
2.         {  
3.             ArrayList al = new ArrayList();  
4.             string
    strConn;  
5.             strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties=/"Excel 8.0;HDR=Yes;IMEX=1;/";";  
6.             OleDbConnection conn = new
    OleDbConnection(strConn);  
7.             conn.Open();  
8.             DataTable sheetNames = conn.GetOleDbSchemaTable  
9.             (System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });  
10.             conn.Close();  
11.             foreach (DataRow dr in sheetNames.Rows)  
12.             {  
13.                 al.Add(dr[2]);  
14.             }  
15.             return al;  
16.         }  

public ArrayList ExcelSheetName(string filepath)        {            ArrayList al = new ArrayList();            string strConn;            strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filepath + ";Extended Properties=/"Excel 8.0;HDR=Yes;IMEX=1;/";";            OleDbConnection conn = new OleDbConnection(strConn);            conn.Open();            DataTable sheetNames = conn.GetOleDbSchemaTable            (System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });            conn.Close();            foreach (DataRow dr in sheetNames.Rows)            {                al.Add(dr[2]);            }            return al;        }

這個方法獲取的EXCEL表名是按字母順序排列的，如果我要獲得EXCEL的第一個工作表名，怎麼做？

其實利用Framework提供的Excel 物件模型很容易解決這個問題,下面是邀月的測試過程及程式碼：
新建一控制檯專案，新增兩個dllMicrosoft.Office.Interop.Excel
Microsoft.VisualBasic
如圖：

新增程式碼：

   
    
     
      [c-sharp] 
      view plain
       copy
       print
      ?
     
    
    

     
using System;  
     
using System.Collections.Generic;  
     
using System.Text;  
     
//add namespace  
     
using Microsoft.Office.Interop.Excel;  
     
  
     
namespace ReadFirstSheetNameDemo  
     
{  
     
    public class Program  
     
    {  
     
        public static void Main(string[] args)  
     
        {  
     
            //Get Xth SheetName of Excel File  
     
            Console.WriteLine(GetFirstSheetNameFromExcelFileName("C://test.xls",1));  
     
            Console.ReadKey();  
     
        }  
     
        public static string GetFirstSheetNameFromExcelFileName(string filepath,int numberSheetID)  
     
        {  
     
            if (!System.IO.File.Exists(filepath))  
     
            {  
     
                return "This file is on the sky??";  
     
            }  
     
            if (numberSheetID <= 1) { numberSheetID = 1; }  
     
            try

                string strFirstSheetName = null;  
     
  
     
                obj = (Microsoft.Office.Interop.Excel.Application)Microsoft.VisualBasic.Interaction.CreateObject("Excel.Application", string.Empty);  
     
                objWB = obj.Workbooks.Open(filepath, Type.Missing, Type.Missing,

                strFirstSheetName = ((Microsoft.Office.Interop.Excel.Worksheet)objWB.Worksheets[1]).Name;  
     
  
     
                objWB.Close(Type.Missing, Type.Missing, Type.Missing);  
     
                objWB = null;  
     
                obj.Quit();  
     
                obj = null;  
     
                return strFirstSheetName;  
     
            }  
     
            catch (Exception Err)  
     
            {  
     
                return Err.Message;  
     
            }  
     
        }  
     
    }  
     
}  
    
   using System;using System.Collections.Generic;using System.Text;//add namespaceusing Microsoft.Office.Interop.Excel;namespace ReadFirstSheetNameDemo{    public class Program    {        public static void Main(string[] args)        {            //Get Xth SheetName of Excel File            Console.WriteLine(GetFirstSheetNameFromExcelFileName("C://test.xls",1));            Console.ReadKey();        }        public static string GetFirstSheetNameFromExcelFileName(string filepath,int numberSheetID)        {            if (!System.IO.File.Exists(filepath))            {                return "This file is on the sky??";            }            if (numberSheetID <= 1) { numberSheetID = 1; }            try            {                Microsoft.Office.Interop.Excel.Application obj = default(Microsoft.Office.Interop.Excel.Application);                Microsoft.Office.Interop.Excel.Workbook objWB = default(Microsoft.Office.Interop.Excel.Workbook);                string strFirstSheetName = null;                obj = (Microsoft.Office.Interop.Excel.Application)Microsoft.VisualBasic.Interaction.CreateObject("Excel.Application", string.Empty);                objWB = obj.Workbooks.Open(filepath, Type.Missing, Type.Missing,                    Type.Missing, Type.Missing, Type.Missing, Type.Missing,                     Type.Missing,Type.Missing, Type.Missing, Type.Missing,                     Type.Missing, Type.Missing,Type.Missing, Type.Missing);                strFirstSheetName = ((Microsoft.Office.Interop.Excel.Worksheet)objWB.Worksheets[1]).Name;                objWB.Close(Type.Missing, Type.Missing, Type.Missing);                objWB = null;                obj.Quit();                obj = null;                return strFirstSheetName;            }            catch (Exception Err)            {                return Err.Message;            }        }    }}
結果：
