在.NET3.5中，我们遇到了同样的问题，似乎已经用这种方法解决了.

I found an answer by googling the error message.

Try resetting Blocking property before each of your reader.ReadLine() statements. In C# that is "client.Blocking = true;", I’m not sure what it is in VB.

We had same problem in .NET3.5 which *seems* to have been resolved with this approach.

在做应用程序的数据库配置时，我做过类似的事情.及其工作正常，希望它会为您提供帮助

I have done some thing similar,in making DB configuration of an application and its working fine,hope it''ll help you

private bool Test()
        {
            bool rvalue = false;
            //Connection String for Windows Authentication
            string cnstr = @"Data Source=" + dbnametxt.Text + ";Initial Catalog=DBname;Integrated Security=True";
            //Connection String for SQL Server Authentication
            string sqlcnstr = @"Data Source=" + dbnametxt.Text + ";Initial Catalog=DBname;uid=" + uidtxt.Text + ";pwd=" + pwdtxt.Text + ";";
            if (radioButton1.Checked)
            {
		//create new connection conn with cnsts
            }
            else if (radioButton2.Checked)
            {
               //create new connection conn with sqlcnstr,and ask for authentication
            }
            if (conn.OpenCon())//checking if server is valid or not,OpenCon() will return true if connection is opened 
            {
                rvalue = false;
            }
            else
            {
                rvalue = true;
            }
            return rvalue;
        }
