C#与Access数据库连接添加图片时为什么数据库的路径会随着图片路径改变

添加图片后数据库的路径会被添加时的图片的路径所代替

请高手给点思路。

谢谢了！

private void pic照片_Click(object sender, EventArgs e)
{

openPic.InitialDirectory = Application.StartupPath;
openPic.FileName = "";
this.openPic.Title = "选择相片";
openPic.Filter = "图片文件(*.jpg;*.bmp;*.gif)|*.jpg;*.bmp;*.gif|所有文件(*.*)|*.*";
if (openPic.ShowDialog() == DialogResult.OK)
{
this.lblpic.Text = openPic.FileName;
this.pic照片.Image = Image.FromFile(openPic.FileName);
picName = DateTime.Now.ToString("yyMMdd") + DateTime.Now.ToString("hhmmss");
string fileName;
int pos = this.openPic.FileName.LastIndexOf("\\");
fileName = this.lblpic.Text.Substring(pos + 1, this.lblpic.Text.Length - pos - 1);
FileInfo fi = new FileInfo(this.lblpic.Text);
fi.CopyTo(Application.StartupPath + @"\picture\" + picName + ".jpg", true);
Environment.CurrentDirectory = Application.StartupPath;
}
}

请使用相对路径
