oleDbCommand访问Excel

大家好，又见面了，我是你们的朋友全栈君。

oleDbCommand访问Excel:
_oleCmdSelect = new OleDbCommand(“SELECT * FROM [Sheet1$A2:A5]”, _oleConn);
objValue = _oleCmdSelect.ExecuteScalar();

using System;
using System.Collections.Generic;
using System.Text;
 
namespace ConsoleApplication1
{
    class Program
    {
        private static string _vsPath = @"Provider=Microsoft.ACE.OLEDB.12.0;
               Data Source=D:\work28\test\Solution2\ReadExcel07\Members.xlsx;Extended Properties=""Excel 12.0;HDR=YES;""";
 
        static void Main(string[] args)
        {
            System.Data.OleDb.OleDbConnection vOleDbConnection = new System.Data.OleDb.OleDbConnection(_vsPath);
            vOleDbConnection.Open();
            System.Data.OleDb.OleDbDataAdapter oleDbDataAdapter=new System.Data.OleDb.OleDbDataAdapter();
            oleDbDataAdapter.SelectCommand = new System.Data.OleDb.OleDbCommand("SELECT * FROM [Sheet1$A2:A5]",vOleDbConnection);
            System.Data.DataTable dataTable=new System.Data.DataTable();
            oleDbDataAdapter.FillSchema(dataTable,System.Data.SchemaType.Source);
            oleDbDataAdapter.Fill(dataTable);
            oleDbDataAdapter.Dispose();
 
            Console.WriteLine("Over");
            Console.Read();
        }
