I got it to read the serial keys but i want it so it reads to see if the key is banned.
the txt file has keys in every line but i want it to be like
EXAMPLE:
key:NotBanned
1337:Banned
This is my code:
private void button3_Click(object sender, EventArgs e)
{
if (keyBOX.Text != "")
{
if (isValid(keyBOX.Text))
{
MessageBox.Show("Valid key!", title, MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
MessageBox.Show("Invalid key!", title, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
else
{
MessageBox.Show("Enter a key!", title, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
public bool isValid(string key)
{
if(String.IsNullOrEmpty(key))
{
return false;
}
using (WebClient wb = new WebClient())
{
foreach (string mKey in wb.DownloadString("the txt file").Split('\n'
)
if (mKey == key) return true;
return false;
}
}
I hope someone can help me with the ban system
Sincerly, MrMods.

Theres a bug on it.
When the key is banned it says banned but then it says invalid.

{
string[] mBits = mKey.Split('|';
if (mBits.Length == 2)
{
MessageBox.Show("Reason for ban:\n\n" + mBits[1]);
return false;
}
if (mKey == Key) return true;
}
}
return false;
}
Obliviously lmao? It's not going to be valid if it's banned. That's not a bug. However, here you go a "fixed" version lol.
public KeyValuePair<bool, string> isValid(string Key)
{
using (WebClient wb = new WebClient())
{
foreach (string mKey in wb.DownloadString("yoursite").Split('\n')
{
string[] mBits = mKey.Split('|';
if(mBits.Length == 2)
return new KeyValuePair<bool, string>(false, mBits[2]);
if (mKey == Key)
return new KeyValuePair<bool, string>(true, "You have successfully been logged in.");
}
}
return new KeyValuePair<bool, string>(false, "Invalid key.");
}
public void exampleCall()
{
var Licence = isValid("ExampleKey");
MessageBox.Show(Licence.Value);
if (Licence.Key)
{
//do what you want if key is valid, errors are handled for you.
}
}

i got a error on
return new KeyValuePair<bool, string>(false, mBits[2]);
this is what i have
private void flatButton3_Click(object sender, EventArgs e)
{
if (keyBOX.Text != "")
{
exampleCall();
}
else
{
MessageBox.Show("Enter a key!", title, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

if (mBits.Length == 2)
return new KeyValuePair<bool, string>(false, mBits[2]);

return new KeyValuePair<bool, string>(true, "You have successfully been logged in.");
}

change mBits[2] to mBits[1] - my bad.
