Hi mahesh213,
Using the below article i have created the example.
Namespaces
using System.IO;
using System.Data;
using System.Data.OleDb;
using System.Configuration;
using System.Data.SqlClient;
Controller
public class HomeController : Controller
{
// GET: Home
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(HttpPostedFileBase postedFile)
{
string filePath = string.Empty;
if (postedFile != null)
{
string path = Server.MapPath("~/Uploads/");
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
filePath = path + Path.GetFileName(postedFile.FileName);
string extension = Path.GetExtension(postedFile.FileName);
postedFile.SaveAs(filePath);
string conString = string.Empty;
switch (extension)
{
case ".xls": //Excel 97-03.
conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString;
break;
case ".xlsx": //Excel 07 and above.
conString = ConfigurationManager.ConnectionStrings["Excel07ConString"].ConnectionString;
break;
}
conString = string.Format(conString, filePath);
using (OleDbConnection connExcel = new OleDbConnection(conString))
{
using (OleDbCommand cmdExcel = new OleDbCommand())
{
using (OleDbDataAdapter odaExcel = new OleDbDataAdapter())
{
cmdExcel.Connection = connExcel;
connExcel.Open();
DataTable dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
for (int i = 0; i < dtExcelSchema.Rows.Count; i++)
{
DataTable dt = new DataTable();
string sheetName = dtExcelSchema.Rows[i]["TABLE_NAME"].ToString();
if (sheetName == "Customers$")
{
connExcel.Close();
connExcel.Open();
cmdExcel.CommandText = "SELECT * From [" + sheetName + "]";

}
}
}
}
}
}
return View();
}
private static void InsertIntoDB(DataTable dt, string tableName)
{

}
}
}
}
