Why does it return true when the not display is used in the try and catch?

ok so I am wanting to know if there is an email in the table, so I have written a method to do just that. In the table there is nothing at all so why does it return true?
private bool FilterUserTableByEmail(string email)
{
FilterUserTableByWebElement(_regRep.FilterByNameEmail(), email);
try
{
//_regRep.emailIDInTable(email);
if (!_regRep.noDataFoundText.Displayed)
{
Console.WriteLine("Email for " + email + " was found in the table.");
}
return true;
}
catch (NoSuchElementException ex)
{
// the search result did not come back in the table - return false
Console.WriteLine("Email for " + email + " was NOT found in the table..." + ex.Message);
return false;
}
}

You can move the return statement to inside the if:
if (!_regRep.noDataFoundText.Displayed)
{
Console.WriteLine("Email for " + email + " was found in the table.");
return true;
}
else
{
return false;
}
Which can be simplified (the else is redundant):
if (!_regRep.noDataFoundText.Displayed)
{
Console.WriteLine("Email for " + email + " was found in the table.");
return true;
}
return false;
Doing this means that the method returns true if an email is found, otherwise it returns false. What you had originally always returned true, unless an exception was thrown.

Try this :
Just added this after if statement :
else
{
Console.WriteLine("Email for " + email + " was NOT found in the table..." + ex.Message);
return false;
}
Full Code :
private bool FilterUserTableByEmail(string email)
{
FilterUserTableByWebElement(_regRep.FilterByNameEmail(), email);
try
{
//_regRep.emailIDInTable(email);
if (!_regRep.noDataFoundText.Displayed)
{
Console.WriteLine("Email for " + email + " was found in the table.");
}
else
{
Console.WriteLine("Email for " + email + " was NOT found in the table..." + ex.Message);
return false;
}
return true;
}
catch (NoSuchElementException ex)
{
// the search result did not come back in the table - return false
Console.WriteLine("Email for " + email + " was NOT found in the table..." + ex.Message);
return false;
}
}

Tcp client in Xamarin.Android

everything seems OK and It's worked in as Server.
I run this code in my Windows 10 mobile (as client) and I can received and send messages between my raspberry pi and windows mobile.
Now I want to send and receive message from my android phone.
I tested a-lot of codes but none of them worked to connect android to raspberry pi.
for android I used this nuget package >
https://github.com/rdavisau/sockets-for-pcl
here is my code:
void Send()
{
var client = new TcpClient();
IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Parse("Ramtin"), 8590);
try
{
client.Connect(ipEndPoint);
if (client.Connected)
{
Debug.WriteLine("Connected to server" + "\n");
var reader = new StreamReader(client.GetStream());
var writer = new StreamWriter(client.GetStream());
writer.AutoFlush = true;
WriteLine("Connected: " + client.Connected);
if (client.Connected)
{
writer.WriteLine("HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEy");
}
else
{
Debug.WriteLine("send failed !");
}
}
}
catch (Exception ex)
{
ex.Exception("Send");
}
}
"Ramtin" is my raspberry pi host name.
How can I solve this?
Thanks.
Note: I tried to create android as Server and other phones as clients and it's works fine(sending/receiving message). but I don't want android as a server!

Get-MailboxPermission exception calling "GetSteppablePipeline"

I am getting an Exception while running the following PoweShell command:
Get-mailboxPermission -Identity MAILBOX_EMAIL |

Multi attach files from DB row

How I can't attach to splited string file name from DB row (I need for "mode = 2" and "case 2:").
In my log file error:
FILE TO ATTACH ERR : Could not find file
'C:\inetpub\wwwroot\PLATFORM_700_NTFSRV\PLATFORM_700_NTFSRV_LAB\Attachments\text.txt,text2.txt'.
Here my example code and my row in DB
Row in db:

public DataTable GetAttachmentFiles(int mode , string fileIDList)

try
{
DataTable DTB = new DataTable();
if (mode == 1)
{
SqlCommand TheCommand = GetCommand("application_MessageAttachFiles", CommandType.StoredProcedure,
GetConnection("APP"));
TheCommand.Parameters.Add("FILEIDLIST", SqlDbType.VarChar, 8000);
TheCommand.Parameters["FILEIDLIST"].Value = fileIDList;
SqlDataAdapter SDA = new SqlDataAdapter();
SDA.SelectCommand = TheCommand;
SDA.Fill(DTB);
}
else if(mode == 2)
{
try
{
DTB.Columns.Add("FILENAME");
string[] fileList = fileIDList.Split(',');
for (int c = 0; c < fileList.Length; c++)
{
DataRow DR = DTB.NewRow();
DR["FILENAME"] = fileList[c];
DTB.Rows.Add(DR);
}
}
catch (Exception ex)
{
RecordLine("ERROR Reading GetAttachmentFiles: " + ex.Message);
}
}
return DTB;
}
catch (Exception eX)
{
RecordLine("ERROR GetAttachmentFiles : " + eX.Message);
return null;
}
}
public Attachment AttachmentFile(int mode, string fileNameString, int fileID, DataRow DRA)
{
// mode.ToString(ConfigurationSettings.AppSettings["MODE"]);
try
{
switch (mode)
{
case 1: /*from Database*/
if (DRA != null)
{
Attachment messageAttachment;
int fileDataSize = int.Parse(DRA["FileSize"].ToString());
string fileType = DRA["FileType"].ToString();
string fileName = DRA["FileName"].ToString();
byte[] fileBuffer = (DRA["FileData"]) as byte[];
MemoryStream ms = new MemoryStream(fileBuffer);
RecordLine("DEBUG 2 - " + fileName + " " + fileType + " " + fileDataSize.ToString() + " " + ms.Length.ToString() + " buffer size:" + fileBuffer.Length.ToString());
messageAttachment = new Attachment(ms, fileName, fileType);

break;
case 2: /*from Local Machin */

return null;
break;
}
return null;
}

I had add this code and it is worked:
foreach (DataRow DRA in DTBA.Rows)
{
message.Attachments.Add(AttachmentFile(2, DRA["FILENAME"].ToString().Trim(), 0, null));
RecordLine("DEBUG 3.1 - " + message.Attachments.Count.ToString());
}

Unable to catch the exception from selenium in C#

I have written some code which deals with C# reflections and selenium to automate the build process of a URL.
But I am unable to catch the exception. What I did is , I exported into .html format from selenium IDE. and parsed and it automatically calls the function related to it from c# code.
but I am unable to catch it. I need help in this regard? Any guesses why it is unable to catch the exception..
I am using Visual Studio Microsoft Visual C# 2010 Express.
And the code is as follows.

If you are trying to catch the exception in your Main() method, you need to bubble your exceptions up in your myFun method. At the moment you are drowning any exceptions in your myFun method.
e.g.
try
{
SeleniumMethod.Invoke(selenium, SeleniumArgs);
}
catch (System.Reflection.TargetInvocationException)
{
throw; //make this bubble up to the calling method.
}
catch (Selenium.SeleniumException se)
{
flag = true;
string lines = "\n Selenium Exception: Caught an exception while executing the script : " + file + " with the command : " + commandNode.InnerHtml.ToString() + " and the XPath is: " + targetNode.InnerHtml.ToString() + " and the value is : " + valueNode.InnerHtml.ToString() + " and the exception is as follows : ";
using (StreamWriter writer = new StreamWriter("Log.txt", true))
{
writer.WriteLine(lines);
writer.Flush();
writer.Close();
}
throw se; //bubble up to calling method
}
//etc...
