    Excel export leading zero problemi in c# from datatable

    I am using the following procedure to create an Excel spreadsheet from a DataTable:

    protected void UploadDataTableToExcel(DataTable dtEmp, string filename)
    string attachment = "attachment; filename=" + filename;
    Response.AddHeader("content-disposition", attachment);
    Response.ContentType = "application/";
    string tab = string.Empty;
    foreach (DataColumn dtcol in dtEmp.Columns)
    Response.Write(tab + dtcol.ColumnName);
    tab = "\t";
    foreach (DataRow dr in dtEmp.Rows)
    tab = "";
    for (int j = 0; j < dtEmp.Columns.Count; j++)
    Response.Write(tab + Convert.ToString(dr[j]));
    tab = "\t";

    It works fine except when the cell only has numbers. For example:

    This "6969062201223401504" becomes "6.96902E+18"
    This "076854957" becomes "76854957"

    I would like the Excel spreadsheet to preserve every column as text, instead of converting them into integers
