SQL, VB.Net | What query can I use grab this value? - mysql

Question

In the above I want it to give me the value of "ID" of the "Username" associated with it.
Here is the command I tried
Dim Query2 = String.Format("SELECT ID FROM account WHERE character = " & UsernameTextBox.Text & " ")
Command = New MySqlCommand(Query2, mydbcon)
Dim idtest = reader.Read.ToString
MsgBox(idtest)
however it is returning "false" what am I doing wrong?
Here is the entire code that I am working on:
Try
mydbcon.Open()
Dim Query As String
Query = String.Format("SELECT * FROM account WHERE username = '{0}' AND password = '{1}'", Me.UsernameTextBox.Text.Trim(), Me.PasswordTextBox.Text.Trim())
Dim Command = New MySqlCommand(Query, mydbcon)
reader = Command.ExecuteReader
Dim count As Integer
count = 0
While reader.Read
count = count + 1
End While
If count = 1 Then
MessageBox.Show("Username and password are correct")
Query = String.Format("SELECT username AS ID FROM account WHERE character = " & UsernameTextBox.Text & " ")
Command = New MySqlCommand(Query, mydbcon)
My.Settings.LoginID = reader.Read
MsgBox(My.Settings.LoginID)
ElseIf count > 1 Then
MessageBox.Show("Username and password are duplicate")
Else
MessageBox.Show("Username and password are wrong")
End If
mydbcon.Close()
Catch ex As MySqlException
MessageBox.Show(ex.Message)
Finally
mydbcon.Dispose()
End Try

Use ID as alias (so select username AS anyNameYouWantToAssignToIt):
Dim Query2 = String.Format("SELECT username AS ID FROM account WHERE character = " & UsernameTextBox.Text & " ")
