Reading data from an Excel file using C#

Wednesday

How to read data of an Excel file using C#?
                                                           By using this code you can read Excel sheet data into dataset. First you have to create a project then create file upload control and a submit button and on button click write the following code.

Code:

using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.OleDb;

public partial class _ParseExcel : System.Web.UI.Page 
{
protected void Page_Load(object sender, EventArgs e)
{ 
}
protected void btnParseExcel_Click(object sender, EventArgs e)
{
string path = System.IO.Path.GetFullPath(uploadFile.PostedFile.FileName);
string connString = "provider=Microsoft.Jet.OLEDB.4.0;" + @"data source="+path +";" + "Extended Properties=Excel 8.0;"; 
OleDbConnection oledbConn = new OleDbConnection(connString);
try
{
oledbConn.Open();
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn);
OleDbDataAdapter oleda = new OleDbDataAdapter();
oleda.SelectCommand = cmd;
DataSet ds = new DataSet();
oleda.Fill(ds, "Table");
GridView1.DataSource = ds.Tables[0].DefaultView;
GridView1.DataBind();
}
catch
{
}
finally
{
oledbConn.Close();
} 
}
}
