Email Notification Automated

Email Notification

Report status mailing to the appropriate team with the following code generation.

Here there are 100 stores and when sending the file to NRI, that NRI sends the file to another environment. We have to check whether the file was successfully transferred to source environment or not.

So, let’s start our programming code,

 Step 1  - Program.cs

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Text;  
  5. using System.Threading.Tasks;  
  6. using System.IO;  
  7. using System.Configuration;  
  8. using System.Data.SqlClient;  
  9. using System.Net.Mail;  
  10. using System.Data;  
  11. namespace Automated_email {  
  12.     class Program {  
  13.         static void Main(string[] args) {  
  14.             //args = new string[] { "DRA#Successful" ,"ISPD#Successful','Complete" };  
  15.             DateTime d = DateTime.Now.Date;  
  16.             string FilePath = "";  
  17.             string session_path = "";  
  18.             session_path = session_path + ConfigurationManager.AppSettings["path"];  
  19.             string dat = d.ToString("D");  
  20.             int p = 0, q = 0;  
  21.             List < clsSessionDtls > lstSessioDtl = new List < clsSessionDtls > ();  
  22.             DataSet dsStat = new DataSet();  
  23.             for (int i = 0; i < args.Length; i++) {  
  24.                 lstSessioDtl.Add(new clsSessionDtls(args[i].Split('#')[0].ToString(), args[i].Split('#')[1].ToString()));  
  25.             }  
  26.             foreach(clsSessionDtls sessionDtls in lstSessioDtl) {  
  27.                 p++;  
  28.                 q = 0;  
  29.                 var connectionString = ConfigurationManager.ConnectionStrings["Email"].ConnectionString;  
  30.                 //Query for generating Session Status  
  31.                 var cmd = "select s.tid,s.Store_No " + ", CASE " + "WHEN q.tid is null THEN 'No' " + " ELSE 'Yes' " + "END Session_Status" + " from stores s left outer join " + "(select distinct Store_Number, (select TID from Stores where [Store_No] = Store_Number) as TID " + "from[dbo].[Job_Session_Summary] where " + " Session_ID in (select[Session_ID] from[dbo].[Job_Sessions] where name = '" + sessionDtls.strSessionName + "') and" + " [LogStatus] in('" + sessionDtls.strCondSql + "') ) q on s.tid = q.tid where s.status='E' and s.[Store_No] <> 'Host'; ";  
  32.                 dsStat.Tables.Add(DataExtraction.ReadTable(connectionString, cmd));  
  33.                 FilePath = session_path + sessionDtls.strSessionName + dat + ".csv";  
  34.                 foreach(DataTable dt in dsStat.Tables) {  
  35.                     q++;  
  36.                     if (p == q) {  
  37.                         FileWriting.WriteToFile(dt, FilePath, false","); //Creation of csv file for Session status  
  38.                         break;  
  39.                     }  
  40.                 }  
  41.             }  
  42.             EmailSending.email(dsStat, lstSessioDtl); //Mailing the status  
  43.         }  
  44.     }  
  45.     public class clsSessionDtls {  
  46.         private string _strSessionName;  
  47.         public string strSessionName {  
  48.             get {  
  49.                 return _strSessionName;  
  50.             }  
  51.             // set { _strSessionName = value; }  
  52.         }  
  53.         private string _strCondSql;  
  54.         public string strCondSql {  
  55.             get {  
  56.                 return _strCondSql;  
  57.             }  
  58.             // set { _strCondSql = value; }  
  59.         }  
  60.         public clsSessionDtls(string sessionName, string stringCondSQL) {  
  61.             _strSessionName = ConfigurationManager.AppSettings[sessionName].ToString();  
  62.             _strCondSql = stringCondSQL;  
  63.         }  
  64.     }  
  65. }  

Step 2

Now we have to write the email body format.

FileWriting.cs

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Text;  
  5. using System.Threading.Tasks;  
  6. using System.IO;  
  7. using System.Configuration;  
  8. using System.Data.SqlClient;  
  9. using System.Net.Mail;  
  10. using System.Data;  
  11. namespace Automated_email {  
  12.     class FileWriting {  
  13.         public static void WriteToFile(DataTable dataSource, string fileOutputPath, bool firstRowIsColumnHeader = false, string seperator = ";") {  
  14.             using(var sw = new StreamWriter(fileOutputPath, false)) {  
  15.                 int icolcount = dataSource.Columns.Count;  
  16.                 if (!firstRowIsColumnHeader) {  
  17.                     for (int i = 0; i < icolcount; i++) {  
  18.                         sw.Write(dataSource.Columns[i]);  
  19.                         if (i < icolcount - 1) sw.Write(seperator);  
  20.                     }  
  21.                     sw.Write(sw.NewLine);  
  22.                 }  
  23.                 foreach(DataRow drow in dataSource.Rows) {  
  24.                     for (int i = 0; i < icolcount; i++) {  
  25.                         if (!Convert.IsDBNull(drow[i])) sw.Write(drow[i].ToString());  
  26.                         if (i < icolcount - 1) sw.Write(seperator);  
  27.                     }  
  28.                     sw.Write(sw.NewLine);  
  29.                 }  
  30.                 sw.Flush();  
  31.                 sw.Close();  
  32.             }  
  33.         }  
  34.     }  
  35. }  

Step 3

Email information: what should be there, what is the condition for success, failure query status and sending email with attachment .

Email Sending.cs

  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Text;

Step 4

Data extraction from Sql query from sql server .

Every session's stored files has a unique extension, where the files are saved to a particular path.
