Why when using filcesystemwatcher and dictionary with fileinfo it's throwing exceptions on wrong key and file not found?

Link for the repository on github :
https://github.com/chocolade1972/FileSystemWatcher
At the top i init with new instance both filelist and dic variables.
Then when starting watching i get all the files . and add them to the filelist and to the dic.
If for example the path is C:\ then filelist will contain 6 items :
filelist = Directory.GetFiles(textBox_path.Text, "*.*").ToList();
foreach (var item in filelist)
{
FileInfo info = new FileInfo(item);
dic.Add(item, info.Length);
}
Then in the event Watcher_Changes at this line :
var info = new FileInfo(e.FullPath);
There is exception the file not found and i see when using a breakpoint a long file temp type with tmp extension.
Then on other files it's throwing exceptions key was not present and then if i will start watching over again it will throw exceptions that the key is the same and already exist.
Other problem is now the button Button_doit in the event Button_doit_Click is not changing to stop and stay on start all the time.

C# display a variable in a Textbox

i am sending Sensor information with a NUCLEOF411RE to my PC. I receive this data on the COM98 with a BaudRate of 115200. Now i want to program a Windows Application that will split my string and put it on my textboxes. until now i display the data with a Button_click event. It puts values on the Textboxes that actually are the real values. But if i move my Sensor and klick the button again there should be a lot more different values, but there are the same values on the textboxes. In addition i want to refresh the textboxes automatically and not with a button click.

can someone help me?

Can you give more information why you use the Button_Click Event to read the text? Maybe it is a possible way for you to subscribe for the DataReceived-Event of the COM-port?
It would look something like this:
serial.DataReceived += new SerialDataReceivedEventHandler(DataReceivedHandler);
private static void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
string receivedString = serial.ReadExisting();
//Do something here...
}

I'd do a couple things. First subscribe to the DataReceived event on the serial port. This event handler will get called when there is data available on the serial port. Then in the event handler you can read from the serial port and add it to your textbox. You can't add it directly (see the AppendText function) because the event handler is called with a different thread, only the UI thread can update UI components (or you'll get a cross-thread exception).
...
public Form1()
{
InitializeComponent();
getAvailablePorts();
// Subscribe to the DataReceived event. Our function Serial_DataReceived
// will be called whenever there's data available on the serial port.
serial.DataReceived += Serial_DataReceived;
}
// Appends the given text to the given textbox in a way that is cross-thread
// safe. This can be called by any thread, not just the UI thread.
private void AppendText(TextBox textBox, string text)
{
// If Invoke is required, i.e. we're not running on the UI thread, then
// we need to invoke it so that this function gets run again but on the UI
// thread.
if (textBox.InvokeRequired)
{
textBox.BeginInvoke(new Action(() => AppendText(textBox, text)));
}
// We're on the UI thread, we can append the new text.
else
{
textBox.Text += text;
}
}
// Gets called whenever we receive data on the serial port.
private void Serial_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
string serialData = serial.ReadExisting();
AppendText(textBox5, serialData);
}

Because i want to add an rotating 3D cube i decided to switch to WPF. I heard it is much easier to implement a 3D graphic there. So i copied my code to the new WPF project. But now i got already problems to visualize my values on the Textboxes. It doesnt work. It looks like the Evenhandler did not fire an event while receiving Data from the com port.

How do I fix the speech synthesizer repeating itself c#?

So basically I used two speech recognition engines(speechrecog & speechrecog1) and one speech synthesizer. When the speechrecog is asked a question like how are you
it then replies I am fine (if the computer picks 2 from the two numbers 1,2). Then it initializes the second speech recognition engine. When it does its stuff. It then turns the second one off and the first one on again. But the problem is when using the second speech recognition engine it repeats( speech synthesizer) the number of times I have tried the second speech recognition engine out.
Here's my code for that form:

For example:
the text file how are you.txt contains:
i am fine. thank you.% how are you#good#bad
and the computer asks if im good and I reply with good. In the good.txt file:
Oh thats cool
the first time I ask her: How are you?
Reply:I am fine thankyou. How are you
User: good
reply: Oh thats cool(1 time)
the 2nd time I ask her: How are you?
Reply:I am fine thankyou. How are you
User: good
reply: Oh thats cool(repeats it 2 times)

How do i fix the repetition problem.

Thanks to #Nikolay Shmyrev I found the solution. As he said my event handler was firing twice. So inside it I put a:
try
{
//My code
}
finally
{
speechrecog1.SpeechRecognized -= speechrecog1_SpeechRecognized;
}

How can i get the listening start time with speechRecognition in c#

I'm doing project in C# that read from a video file and convert it to subtitle text, but i want to get the start time for each text line so it can be shown in the video at the right time, i tried the AudioPosition but it not working well, is there a away to do this?
using System;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Speech.Recognition;
using System.Threading.Tasks;
namespace project
{
public partial class Form1 : Form
{
StringBuilder sb = new StringBuilder();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
string[] tokens;
private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "WAV|*.wav";
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
}
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
Grammar gr = new DictationGrammar();
sre.LoadGrammar(gr);
sre.SetInputToWaveFile(#openFileDialog1.FileName);
while (true)
{
try
{
var recText = sre.Recognize();
sb.Append(recText.Audio.AudioPosition + " * ");
textBox4.Text = sb.ToString();
tokens = sb.ToString().Split('#');
for (int i = 0; i < tokens.Length - 1; i++)
{
textBox2.AppendText(tokens.Length.ToString());
textBox2.AppendText(i+" - "+tokens[i]);
textBox2.AppendText(Environment.NewLine);
}
}
catch (Exception ex)
{
break;
}
}
}

C# Server-Client App(One Server-Multi Client)

I want to develop a client-server application. I started the project but I encountered the some problems. When I want to connect to server with one client, everything is done. Program is working. But when I want to connect with two or three etc. PC to server, clients of them is working but others is not working. How can I fix this problem?
Here is the my code;

STW.AutoFlush = true;
backgroundWorker1.RunWorkerAsync(); //receive data background

}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e) //receive data
