I not familiar and i don't know any thing about  C#,  but i am learning SSIS on my own.
I tried to send mail to gmail  using script task , both sender and receiver with same mail ID using variables which i tried using tutorial i found from the below link.
[quote]http://www.codeproject.com/Articles/85172/Send-Email-from-SSIS-with-option-to-indicate-Email[/quote]
but finally when i execute the task , it returns failure message and email is not sent.
[quote]SSIS package "Send mail using script task.dtsx" starting.
Error: 0x8 at Script Task: The script returned a failure result.
Task failed: Script Task
SSIS package "Send mail using script task.dtsx" finished: Success.

Below message taken from progress tab
[quote]Error: The script returned a failure result.[/quote]
Can you all please help me in  finding where i am going wrong? please check below code which i have used in script task.
Microsoft SQL Server Integration Services Script Task
Write scripts using Microsoft Visual C# 2008.
The ScriptMain is the entry point class of the script.
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Runtime;
using System.Windows.Forms;
using System.Text.RegularExpressions;
using System.Net.Mail;
namespace ST_9bc84810a62a401aa44ddd905bcd369d.csproj
[System.AddIn.AddIn("ScriptMain", Version = "1.0", Publisher = "", Description = "")]
public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
#region VSTA generated code
enum ScriptResults
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
#endregion
The execution engine calls this method when the task executes.
To access the object model, use the Dts property. Connections, variables, events,
and logging features are available as members of the Dts property as shown in the following examples.
To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
To post a log entry, call Dts.Log("This is my log text", 999, null);
To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);
To use the connections collection use something like the following:
ConnectionManager cm = Dts.Connections.Add("OLEDB");
cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";
Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
To open Help, press F1.
public void Main()
string sSubject = "Test Subject";
string sBody = "Test Message";
int iPriority = 2;
if (SendMail(sSubject, sBody, iPriority))
Dts.TaskResult = (int)ScriptResults.Success;
else
//Fails the Task
Dts.TaskResult = (int)ScriptResults.Failure;
public bool SendMail(string sSubject, string sMessage, int iPriority)
try
string sEmailServer = Dts.Variables["sEmailServer"].Value.ToString();
string sEmailPort = Dts.Variables["sEmailPort"].Value.ToString();
string sEmailUser = Dts.Variables["sEmailUser"].Value.ToString();
string sEmailPassword = Dts.Variables["sEmailPassword"].Value.ToString();
string sEmailSendTo = Dts.Variables["sEmailSendTo"].Value.ToString();

Thank you very much for your reply @Elvis Long,
Sorry for the late reply
Actually, i am not trying or executing this task  from my office , but i am trying this at my home :( .
sEmailPort has value 587 sEmailServer has smtp.gmail.com
Can you please check whether this C# coding is correct or not ? because finally it gives error saying "Script
Task: The script returned a failure result" 
so can you please check this with your system and let me know what is wrong with this code
Thanks in advance
