In this post , We will learn how to Import excel data to SQL using C# with the help of OLEDB . This is a time saver especially if you want to add tons and tons of data to your table within a fraction of second a so let’s get started.
First thing first , Create a table in SQL-Server database (you can copy paste following code to your SQL-Server to relate flawless with the following article).
CREATE TABLE [dbo].[tbl_registration]( [Sr_no] [int] IDENTITY(1,1) NOT NULL, [Email] [nvarchar](100) NULL, [Password] [nvarchar](max) NULL, [Name] [varchar](max) NULL, [Address] [nvarchar](max) NULL, [City] [nvarchar](max) NULL )
Now, Add connection string to your Web.config file.
<connectionStrings> <add name="con" connectionString="Server=YourServerName;Initial Catalog=YourDatabaseName;Persist Security Info=False;User ID=YourUserName;Password=YourUserPassword;MultipleActiveResultSets=True;Encrypt=False;TrustServerCertificate=False;Connection Timeout=30;" providerName="System.Data.SqlClient" /> </connectionStrings>
Note :- Change Server,Initial Catalog,User ID,Password values as per your server properties
Now, Add the following code to your Index.cshtml file
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div>
<h2>Excel Import</h2>
<form method="post" enctype="multipart/form-data" class="form-group">
<div>
<input name="file" type="file" class="form-control-file" required />
<button type="submit" class="btn btn-primary">Import</button>
</div>
</form>
</div>
</body> Next step , Add Following Code to your Home Controller
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
OleDbConnection econ;
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(HttpPostedFileBase file)
{
string filename = Guid.NewGuid() + Path.GetExtension(file.FileName);
string filepath = "/excelfolder/" + filename;
file.SaveAs(Path.Combine(Server.MapPath("/excelfolder"), filename));
InsertExceldata(filepath, filename);
return View();
}
private void ExcelConn(string filepath)
{
string constr = string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=YES;""", filepath);
econ = new OleDbConnection(constr);
}
private void InsertExceldata(string fileepath, string filename)
{
string fullpath = Server.MapPath("/excelfolder/") + filename;
ExcelConn(fullpath);
string query = string.Format("Select * from [{0}]", "Sheet1$");
OleDbCommand ecom = new OleDbCommand(query, econ);
econ.Open();
DataSet ds = new DataSet();
OleDbDataAdapter oda = new OleDbDataAdapter(query, econ);
econ.Close();
oda.Fill(ds);
DataTable dt = ds.Tables[0];
SqlBulkCopy objbulk = new SqlBulkCopy(con);
objbulk.DestinationTableName = "tbl_registration";
objbulk.ColumnMappings.Add("Email", "Email");
objbulk.ColumnMappings.Add("Password", "Password");
objbulk.ColumnMappings.Add("Name", "Name");
objbulk.ColumnMappings.Add("Address", "Address");
objbulk.ColumnMappings.Add("City", "City");
con.Open();
objbulk.WriteToServer(dt);
con.Close();
} Note :- Add a folder namely excelfolder in your project.
And that’s it You can run the Project
