public void exportsqldatatoexcle()
{
    string con1 = "Data Source=ADMIN\\SQLEXPRESS;Initial Catalog=PhysioCure; Integrated Security=true";
    SqlConnection connection = new SqlConnection(con1);
    connection.Open();
    sda = new SqlDataAdapter("select PationName,RegistrationDate,ContactNo,Age,Sex,Chief_Complain,Investigation_Result,PastHistoryAny,Physical_Examination,Medications,Prognosis,Electro_Therapy,Neuro_Rehabilitation,Ortho_Rehabilitation,Cardio_Pulmonery_Rehabilitation,Sports_Rehabilitation from Physio_cureTable order by RegistrationDate desc", con1);

    Microsoft.Office.Interop.Excel.ApplicationClass excelapp = new Microsoft.Office.Interop.Excel.ApplicationClass();
    excelapp.Application.Workbooks.Add(Type.Missing); 

    for (int i = 1; i < dt.Rows.Count + 1; i++)

            {
                excelapp.Cells[i, j] = dccollection[j - 1].ToString();
            }
            else

如果您可以封装进程以通过命令行应用程序中的电子邮件发送文件，则可以使用Windows任务计划程序安排它。

我推荐使用SSIS和SQL Agent，或SSRS，但由于看起来您使用的是SQL Express，因此可能没有这些选项。
