private void button1_Click(object sender, EventArgs e)
{
using (SqlConnection coon = new SqlConnection(@"Server=.\SQLExpress;AttachDbFilename=G:\WPF\cadADO\cadADO\bin\Debug\Database1.mdf;Trusted_Connection=sspi;"))
{
coon.Open();
MessageBox.Show("连接成功");
}
}
}
}
在CAD里面用AttachDbFilename=|DataDirectory|Database1.mdf就发生错误，必须用AttachDbFilename=G:\WPF\cadADO\cadADO\bin\Debug\Database1.mdf。怎么才能使用相对路径连接数据库呢？
