Exception has been thrown by the target of an invocation?

I have an exception and I couldn't find a solution for my problem. I think my whole code is valid c#.
namespace YoutubeDownloader2Form
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private async void button1_Click(object sender, EventArgs e)
{
DownloadUrl DownloadUrl = new DownloadUrl();
List<Class1> FinalLiast = DownloadUrl.DownloadUrlMethod(textBox1.Text);
int i = 0;
foreach (var Urls in FinalLiast)
{
string Authorization = Urls.Author;
IEnumerable<VideoInfo> videoInfos = DownloadUrlResolver.GetDownloadUrls(Urls.Url);
VideoInfo Video = videoInfos.First(info => info.VideoType == VideoType.Mp4 && info.Resolution == 144);
if (Video.RequiresDecryption)
{
DownloadUrlResolver.DecryptDownloadUrl(Video);
}
string path = Directory.CreateDirectory(#"C:\Youtube\" + Authorization).ToString();
var videoDownloader = new VideoDownloader(Video,
Path.Combine((#"C:\youtube\" + path), Video.Title + Video.VideoExtension));
StreamWriter dosya = File.AppendText((#"C:\youtube\" + path) + i + ".txt");
videoDownloader.Execute();
//Thread.Sleep(60000);
i++;
}
}
}
}
public class DownloadUrl
{
public List<Class1> DownloadUrlMethod(string txtboxDeger)
{
VideoSearch Items = new VideoSearch();
List<Class1> ListClass1 = new List<Class1>();
string searchCount =
txtboxDeger + "&sp=EgIYAVAU";
foreach (var Item in Items.SearchQuery(searchCount, 1))
{
Class1 Video = new Class1();
Video.title = Item.Title;
Video.Author = Item.Author;
Video.Url = Item.Url;
IEnumerable<VideoInfo> videos = DownloadUrlResolver.GetDownloadUrls(Video.Url);
ListClass1.Add(Video);
}
return ListClass1;
}
}
The code works fine for three queries, but I have 20. At 3. step, it throws an exception; here's the stack trace:

You can see from picture where the code throws. I tried asynchronously, and it also throws. I checked the InnerException; it says that the given path's format is not supported. But, it downloaded first three videos successfully. It should work fine for other videos too.
Why is this code throwing an exception?
I followed these tutorials to write this code:

Oracle.DataAccess.Client.OracleException C#

I have this class where I am selecting two values from the database and comparing it to the textbox values provided by the users. Below is my class.
public void Userlogin(TextBox username, TextBox pwd)
{
int _failedAttempt = 0;
OpenConnection();
command = new OracleCommand();
command.CommandText = "SELECT username, user_pwd FROM dinein_system_users WHERE username:usrname AND user_pwd:pwd";
command.Connection = dbconnect;
command.BindByName = true;
try
{
command.Parameters.Add("usrname", username.Text);
command.Parameters.Add("pwd", pwd.Text);
}
catch (NullReferenceException NRE)
{
MessageBox.Show("Please contact your developer about this error. Thank you " + NRE);
}
_reader = command.ExecuteReader();
if (_reader.Read() != true)
{
_failedAttempt = _failedAttempt + 1;
while (_failedAttempt < 3)
{
MessageBox.Show("Incorrect Username or Password. Please try again " + "Attempts: " + _failedAttempt);
username.ResetText();
pwd.ResetText();
}
}
else
{
MessageBox.Show("Welcome");
}
}
my connection string
this._connectionString = "Data Source=xe;Max Pool Size=50;Min Pool Size=1;Connection Lifetime=120;Enlist=true;User Id=hr;Password=hr";
So when the program is executed I am getting this error
An unhandled exception of type 'Oracle.DataAccess.Client.OracleException' occurred in Oracle.DataAccess.dll
Additional information: External component has thrown an exception. I have been at this for the past hour any help would be appreciated.
Update

{

return;
}
}

Rather than using your separate OpenConnection() method, consider coding with the using() statement. It will ensure that your connection an other database-related objects are always disposed.
For example:
int _failedAttempt = 0;
public void Userlogin(TextBox username, TextBox pwd)
{
try
{
using (var connection = new OracleConnection(_connectionString))
{
connection.Open();
using (var command = new OracleCommand())
{
command.CommandText = "SELECT username, user_pwd FROM dinein_system_users WHERE username= :usrname AND user_pwd= :pwd";
command.Connection = connection;
command.BindByName = true;
command.Parameters.Add("usrname", username.Text);
command.Parameters.Add("pwd", pwd.Text);
using (var reader = command.ExecuteReader())
{
if (reader.Read() != true)
{
_failedAttempt += 1;
if (_failedAttempt < 3)
{
MessageBox.Show("Incorrect Username or Password. " +
"Please try again. " +
$"Attempts: {_failedAttempt}");
username.ResetText();
pwd.ResetText();
}
else
{
// 3 failed attempts
}
}
else
{
_failedAttempt = 0;
MessageBox.Show("Welcome");
}
}
}
}
}
catch(OracleException ex)
{
MessageBox.Show("Error: {ex}");
}
}

String Invoke Issue

I am using a backgroundworker and I think there is a cross thread thing.. But I cant solve it.
my code is here
private void bgworkerGameLoad_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
var arg = e.Argument.ToString();
var liste = webHelper.ShowGame("http://www.abx.com/" + arg);
txtHowToPlay.Invoke(new Action(() => txtHowToPlay.Text = String.Format("Oyun Bilgi: {0}", liste[0])));
txtInfo.Invoke(new Action(() => txtInfo.Text = String.Format("Nasıl Oynanır: {0}", liste[1])));
bgworkerGameLoad.ReportProgress(0,liste[2]);
}
private void bgworkerGameLoad_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
if (FlashPlayerActive)
UnLoad();
string url="";
Invoke(new MethodInvoker(() =>
{
url= e.UserState.ToString();
Thread.Sleep(2);
}));
axShockwaveFlash1.Movie = url;
LoadFlash();
pbWaitForChannelLoading.Visible = false;
axShockwaveFlash1.Play();
}
the problem is that I cant get the e.UserState.ToString() for my shocwaveplayer. I used a local string variable but its the same result.
it is occured targetofaninvocation exception in program.cs
Application.Run(new FrmMain());;
but that code is in frmMain.cs
this is detail of the exception
System.Reflection.TargetInvocationException was unhandled

what is my mistake? I tried to use delegate but its the same..

It sounds like the problem is as simple as e.UserState being null. You don't even need to use Invoke to get at UserState - you'll see the same problem if you just have:
if (FlashPlayerActive)
UnLoad();
string url = e.UserState.ToString();
Thread.Sleep(2); // This is generally a bad idea anyway, btw...
Where are you setting the UserState? I suspect you're not setting it anywhere, so it's still null, which is why you're getting an exception.

I solved the problem..
I hadnt added axShockwaveFlash1 to my form before set values..
in LoadFlash function, it was
public void LoadFlash()
{
axShockwaveFlash1 = new AxShockwaveFlash();
axShockwaveFlash1.BeginInit();
axShockwaveFlash1.Location = new Point(14, 196);
axShockwaveFlash1.Name = "Test Movie";
axShockwaveFlash1.TabIndex = 0;
axShockwaveFlash1.Movie = liste[2];
axShockwaveFlash1.EmbedMovie = true;
axShockwaveFlash1.AutoSize = true;
axShockwaveFlash1.Size = new Size(640, 480);
axShockwaveFlash1.Visible = true;
axShockwaveFlash1.EndInit();
splitContainerControl.Panel2.Controls.Add(axShockwaveFlash1);
FlashPlayerActive = true;
}
but i changed this code like
public void LoadFlash()
{
axShockwaveFlash1 = new AxShockwaveFlash();
splitContainerControl.Panel2.Controls.Add(axShockwaveFlash1);
axShockwaveFlash1.BeginInit();
axShockwaveFlash1.Location = new Point(14, 196);
...
it works..
