First of all create Excel workbook as shown in image below and insert some data into it. Please design excel sheet like whatever I shown in image
I want to copy this data into a SQL Server Database Table, called Excel_table, with the same schema. Design your tables in database like this
Design your aspx page like this
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>
<span style="color: Red">*</span>Attach Excel file
</td>
<td>
<asp:FileUpload ID="fileuploadExcel" runat="server" />
</td>
</tr>
<tr>
<td></td>
<td>
<asp:Button ID="btnSend" runat="server" Text="Export" onclick="btnSend_Click" />
</td>
</tr>
</table>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
</form>
</body>
</html>
|
After that write the following code in codebehind button click
protected void btnSend_Click(object sender, EventArgs e)
{
String strConnection = "Data Source=MySystem;Initial Catalog=MySamplesDB;Integrated Security=True";
//file upload path
string path = fileuploadExcel.PostedFile.FileName;
//Create connection string to Excel work book
string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;Persist Security Info=False";
//Create Connection to Excel work book
OleDbConnection excelConnection =new OleDbConnection(excelConnectionString);
//Create OleDbCommand to fetch data from Excel
OleDbCommand cmd = new OleDbCommand("Select [ID],[Name],[Designation] from [Sheet1$]",excelConnection);
excelConnection.Open();
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);
//Give your Destination table name
sqlBulk.DestinationTableName = "Excel_table";
sqlBulk.WriteToServer(dReader);
excelConnection.Close();
}
}

Here I will explain about this query clearly "Select [ID], [Name],[Designation] from [Sheet1$]"
By using this query we are getting data from Sheet1 of Excel sheet that's why i have circled Sheet1 in Excel sheet if you change the Sheet1 name in excel sheet u need to change the Sheet1 in query also don't forgot.
Here don't forget to close the connection of your Excel file otherwise you will get error
