I have this code down which I tried to make it Test SQL string connectivity, but I dont know how to handle the part with connection.Open = true
would you please help me to solve this out? Thank you so much for your time.
private void button1_Click(object sender, EventArgs e)
{
try
{
using (SqlConnection connection = new SqlConnection("Data Source='" + textBox1.Text + "';Initial Catalog='" + textBox2.Text + "';User ID='" + textBox3.Text + "';Password='" + textBox4.Text + "'"))
{
try
{
connection.Open();
if (connection.Open == true) // if connection.Open was successful
{
MessageBox.Show("You have been successfully connected to the database!");
}
else
{
MessageBox.Show("Connection failed.");
}
}
catch (SqlException) { }
}
}
catch (Exception ex)
{
MessageBox.Show("Chyba v přihlášení: " + ex);
}
finally
{
}
}
It says: "Cannot asign 'open' because it is a 'methoud group' " I know that this code might be totaly bad, but I need to handle this somehow and have no idea what is the right way. Thank you.
This is what is not actually working for not-opened connection:
using (SqlConnection connection = new SqlConnection("Data Source='" + textBox1.Text + "';Initial Catalog='" + textBox2.Text + "';User ID='" + textBox3.Text + "';Password='" + textBox4.Text + "'"))
{
connection.Open();
if (connection.State == ConnectionState.Open)
{
MessageBox.Show("Spojení s databázi problěhlo úspěšně.");
}
connection.Close();
if (connection.State == ConnectionState.Closed)
{
MessageBox.Show("Spojení selhalo");
}
}
