数据表中删除记录 避免用 Delete 应单独设置字段,防止误删

private void DeleteProductInfo(int TempID)

{

    SqlConnection con = null;

    bool flag = false;

    try

    {

        con = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);

        string sql = "update T_Temp set Deleted=1 where TempID=" + TempID;

        con.Open();

        SqlCommand com = new SqlCommand(sql, con);

        flag = com.ExecuteNonQuery() > 0 ? true : false;

        con.Close();

    }

    catch (SqlException se) { }

    finally

    {

        con.Close();

    }

    if (flag)

    {

        myShare.WebMessageBox(this.Page, "删除成功！");

    }

    else

    {

        myShare.WebMessageBox(this.Page, "删除信息时出错，请重试！");

    }

}
