C# connect to database

I have a C# application. I noticed if the app cannot make a connection to the database the program hangs but does eventually come back with an error that it cannot connect. But the time it takes to respond t hat there is no connection is quite awhile and you may think that it has hung.

Is t here any way to quickly check if t here is a connection and if there is no service it reports it quickly.

It might be different depending on how you connect to the database, but for most programmers, setting the ConnectionTimeOut property of the SqlConnection object to the number of seconds that you want to wait if sufficient. You can set that through the property or through a the connectionstring.

SqlConnection con = New SqlConnection("yourConnectionString");
con.ConnectionTimeOut=5;
con.Open();

Thank you James

Do you know what the default is if you do not set the timeout property?

According to the documentation, the default is 15 seconds. I never measured. It seems longer than that, but human beings are impatient when a computer seems to be slow, so it might be right.

JamesBurger is right.

MySql Offers a Connection.Ping() method that returns true or false even if you haven't called Connection.Open() before.

For Sql server

If connection string is wrong this will throw an exception

public static class Extension
{
    public static void TestDbConnection(this DbConnection connection)
    {
        var builder = new DbConnectionStringBuilder
            {
                ConnectionString = connection.ConnectionString
            };
    }
}
