Question

Am having one excel file with 2 different worksheets as fundmodelrate and project.Now I want to import these 2 different sheet values into 2 different sql tables(k2_fundmodelrate,k2_project).I can able to do import only if am working with 1 sheet and and 1 table,but I want two sheets values to be imported on two tables at the same time on button click event.
My code below:

private String strConnection = "Data Source=kuws4;Initial Catalog=jes;User ID=sa;Password=******";               
        protected void btnSend_Click(object sender, EventArgs e)
        {

            string path = fileuploadExcel.PostedFile.FileName;

            string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\fmr.xls;Extended Properties=Excel 12.0;Persist Security Info=False";

            OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);

            OleDbCommand cmd = new OleDbCommand("Select * from [FundModelRate$]", excelConnection);
            //OleDbCommand cmd1 = new OleDbCommand("Select * from [FundModelRate$],  [Project$]", excelConnection);
            excelConnection.Open();
            OleDbDataReader dReader;
            dReader = cmd.ExecuteReader();
            SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);

            sqlBulk.DestinationTableName = "K2_FundModelRate";
           // sqlBulk.DestinationTableName = "K2_Project";
            sqlBulk.WriteToServer(dReader);
            excelConnection.Close();
        }

I think the only way is to loop through your two sheets.

Have a look at This post. This will help you get the sheet names.

When you have the sheet names, you can then just loop through them and then load them into SQL.

Maybe this can help you:

OleDbConnection objConn = null;
System.Data.DataTable dt = null;
string excelConnection = "";

if(strFile.Trim().EndsWith(".xlsx"))
{
    excelConnection = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0 Xml;HDR=YES;IMEX=1\";", strFile);
}
else if(strFile.Trim().EndsWith(".xls")) 
{
    excelConnection = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=1\";", strFile);
}

objConn = new OleDbConnection(excelConnection);

objConn.Open();

dt = objConn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

String[] excelSheets = new String[dt.Rows.Count];
int i = 0;

foreach(DataRow row in dt.Rows)
{
    excelSheets[i] = row["TABLE_NAME"].ToString();
    i++;
}

for(int j=0; j < excelSheets.Length; j++)
{
    OleDbCommand cmd = new OleDbCommand("Select * from " + excelSheets[j], excelConnection);

    excelConnection.Open();
    OleDbDataReader dReader;
    dReader = cmd.ExecuteReader();
    SqlBulkCopy sqlBulk = new SqlBulkCopy(strConnection);

    sqlBulk.DestinationTableName = "YourDestinationTableName";

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