Make a .CS file with name of ImportExcel.CS
:----
public class FileExt : ValidationAttribute
    {
        public string Allow;
        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            if (value != null)
            {
                string extension = ((System.Web.HttpPostedFileBase)value).FileName.Split('.')[1];
                if (Allow.Contains(extension))
                    return ValidationResult.Success;
                else
                    return new ValidationResult(ErrorMessage);
            }
            else
                return ValidationResult.Success;
        }
    }

    public class ImportExcel
    {
        [Required(ErrorMessage = "Please select file")]
        [FileExt(Allow = ".xls,.xlsx", ErrorMessage = "Only excel file")]
        public HttpPostedFileBase file { get; set; }
    }



And Add this code to your controller
:-----

public ActionResult ImportExcel()
       {
           return View();
       }

       [HttpPost]
       public ActionResult importexcel(ImportExcel importExcel)
       {
           if (ModelState.IsValid)
           {
               string path = Server.MapPath("~/library/ExcelFile/" + importExcel.file.FileName);
               importExcel.file.SaveAs(path);

               string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source='" + path + "';Extended Properties='Excel 12.0;'";
               OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);

               //Sheet Name
               excelConnection.Open();
               string tableName = excelConnection.GetSchema("Tables").Rows[0]["TABLE_NAME"].ToString();
               excelConnection.Close();
               //End

               OleDbCommand cmd = new OleDbCommand("Select * from [" + tableName + "]", excelConnection);

               excelConnection.Open();

               OleDbDataReader dReader;
               dReader = cmd.ExecuteReader();
               SqlBulkCopy sqlBulk = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);

               //Give your Destination table name
               sqlBulk.DestinationTableName = "ExcelFile";

               //Mappings
               sqlBulk.ColumnMappings.Add("Userid", "Userid");
               sqlBulk.ColumnMappings.Add("Name", "Name");
               sqlBulk.ColumnMappings.Add("TelephoneNo", "TelephoneNo");
               sqlBulk.ColumnMappings.Add("Address", "Address");
               sqlBulk.ColumnMappings.Add("EmailAddress", "EmailAddress");


               sqlBulk.WriteToServer(dReader);
               excelConnection.Close();

               ViewBag.Result = "Successfully Imported";
           }
           return View();
       }





And create view page of ImportExcel method with name of ImportExcel.cshtml and add this code
:-----



@model Models.GeneralModel.ImportExcel



<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>ImportExcel</title>
</head>
<body>
    <div style="float:right"> 
        <h4>@ViewBag.Result</h4>
        @using (Html.BeginForm("ImportExcel", "NewCustomer", FormMethod.Post, new { enctype = "multipart/form-data" }))
        {
            @Html.TextBoxFor(m => m.file, new { type = "file" })
            <button id="submitButton" type="submit">Submit</button>
            @Html.ValidationMessageFor(model => model.file)
        }
    </div>
</body>
</html>
