这是我的代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.OleDb;
namespace SDD_Single_Project___Michael_Merjane
{
public partial class NewUser : Form
{
private OleDbConnection connection = new OleDbConnection(); //setting up a private connection
public NewUser()
{
InitializeComponent();
connection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\schoolwork\Year 11\SDD\3 SINGLE TASK\SDD Single Project - Michael Merjane\SDD Single Project - Michael Merjane\bin\Persondata.accdb; //PROBLEM IS HERE
Persist Security Info=False;"; // there is no security for finding the location, this is not very safe but for the circumstances it works. In the line above, it is finding the location of the database. This could change due to computer and cause the whole program to not run
}
private void btnBack_Click(object sender, EventArgs e) //all of these mean when button is clicked
{
this.Hide(); //hides this page
MainScreen frm = new MainScreen(); //finds the next screen (the main screen)
frm.Show(); //shows it
}
private void btnSubmit_Click(object sender, EventArgs e)
{
try {
connection.Open(); // opens the connection
OleDbCommand command = new OleDbCommand(); //names command as a new oledbcommand for further use
command.Connection = connection;
command.CommandText = "insert into Persondata ( FirstName,LastName,Address,Suburb,Email,Mobile,Gender,Age) values ( '" + txtFirst.Text + "' , '" + txtLast.Text + "' , '" + txtAddress.Text + "' , '" + txtSuburb.Text + "' , '" + txtEmail.Text + "' , '" + txtMobile.Text + "' , '" + dropGender.Text + "' , '" + dropAge.Text + "') ";
// finds where its going to, finds the columns it is going to fill, finds the text boxes that is going to fill them
command.ExecuteNonQuery(); //execute the save
MessageBox.Show("Data Saved"); //pretty much shows a box saying everything worked
connection.Close(); // closes the connection
}
catch (Exception ex) //if something has gone wrong a catch will occur
{
MessageBox.Show("Error " + ex); //show the error
} //if there is a error message box will appear informing it
}
}
}
这是我必须提交的作业的代码,问题是我无法交出它,因为这样绝对路径将找不到文件。我需要一种使用相对文件路径的方法,该路径会因位置的变化而改变。目前,路径(只要它是)进入程序文件中的 bin 文件夹。因此,如果有办法改变它,让它以某种方式自动在自己的程序文件中查找 bin 或在自己的程序文件中的任何其他地方,那就太好了。
