I've a software in which data is stored in excel database columns are Product_ID & Description. I've included searching feature which displays result based on Product_ID. But the problem is it only retrieves/read/search data when that excel file is open but i want to read data without opening excel file ? Is there any way to do this ???? My code is for searching -:

public Form3()
  {
      InitializeComponent();
  }
 
  private void button1_Click(object sender, EventArgs e)
  {
      srch();
  }
 
  private void srch()
  {
      DataTable sheetData = new DataTable();
      string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source= 'c:\\Product Details.xlsx';Extended Properties='Excel 8.0;HDR=Yes;'";
      string query = "select * from [Sheet1$]" ;
 
      DataSet excelDataSet = new DataSet();
      OleDbDataAdapter da = new OleDbDataAdapter(query, strConn);
      da.Fill(excelDataSet);
      dataGridView1.DataSource = excelDataSet.Tables[0];
      DataView dv = ((DataTable)dataGridView1.DataSource).DefaultView;
      DataView dv_filter = new DataView();
      dv_filter.Table = excelDataSet.Tables[0];
      dv_filter.RowFilter = "Product_ID = '" + textBox1.Text + "'";
      dataGridView1.DataSource = dv_filter;
 
  }

You could use an excel library written in C# for this, the following article demonstrates how to read your excel files in C# (note it does not open the file) and also the following shows how to export that excel's data into a DataTable in C#.
