string strdata = textBox1.Text;
string strsa = textBox2.Text;
string strpwd = textBox3.Text;

SqlConnectionStringBuilder sqlb01 = new SqlConnectionStringBuilder();

sqlb01.DataSource = strdata;

sqlb01.InitialCatalog = "random";
sqlb01.UserID = strsa;
sqlb01.Password = strpwd;
sqlb01.IntegratedSecurity = false;
sqlb01.Pooling = true;
SqlConnection conn01 = new SqlConnection();
conn01.ConnectionString = sqlb01.ConnectionString;
MessageBox.Show(sqlb01.ConnectionString);

try
{
conn01.Open();
if (conn01.State.ToString() == "Open")
{
MessageBox.Show("数据库链接成功!");

conn01.Close();
}

}
