這是我的插入數據類,我想在我的Windows窗體中顯示異常錯誤就像一個消息框我該如何顯示異常消息?C#:拋出異常其他類
public void Insert()
{
try
{
objcomm.Connection = objconn;
objcomm.CommandText = "INSERT INTO goods VALUES(N'" + g_id + "',N'" + g_name + "',N'" + g_qty + "',N'" + b_price + "',N'" + s_price + "',N'" + l_qty + "',N'" + co_id + "')";
objconn.Open();
objcomm.ExecuteNonQuery();
objconn.Close();
}
catch(Exception ex)
{
GeneralException ex1 = new GeneralException(Resource1.DBError, ex);
throw ex1;
}
}
我想顯示「Resource1.DBError」消息時,異常在消息框中這裏被拋出:
public partial class WareForm : Form
{
try
{
ware.Insert();
}
catch(IndexOutOfRangeException ex)
{
MessageBox.Show(ex.Message);
}
}
非常感謝你 – 2013-04-22 11:00:35
