Question

我有一个表单，用户可以注册必填字段，并且可以选择在其桌面上浏览图像。我没有将实际图像保存在数据库中。我使用了Openfile对话框，当用户选择图像时，它将路径复制到标签，所选图像将保存在我的项目文件夹中，并且路径将保存在数据库中。现在的问题是，如果用户不想拥有一张图片该怎么办？为了解决此问题，我使用资源以编程方式将图片设置到了我的图片框。这是现在的问题，我如何获取图片框的图像路径（图像位于资源中）并将其复制到标签中，还可以看到我具有File.Copy功能，我不希望在以下情况下启用此代码用户未选择任何图像。

PS：如果没有上传的图片，则为默认图片，例如facebook

public partial class RegisterCustomer : UserControl
{
    public RegisterCustomer()
    {
        InitializeComponent();
        UserImage.Image = Properties.Resources.User;
        //var img = Image.FromFile(@"C:\Users\dieth\source\repos\SalesInventoryManagement\SalesInventoryManagement\bin\Debug\Icons\User.png");
        //UserImage.Image = img;
    }     
    Register rc = new Register();
    private void Btn_Register_Click(object sender, EventArgs e)
    {
        File.Copy(lbl_location.Text, Path.Combine(@"C:\Users\dieth\source\repos\SalesInventoryManagement\SalesInventoryManagement\bin\Picture", Path.GetFileName(lbl_location.Text)), true);
        rc.Insert(lbl_location.Text, string.Format(txt_firstname.Text + " " + txt_middlename.Text + " " + txt_lastname.Text), cbox_gender.Text, txt_contact.Text, txt_email.Text, txt_address.Text, Variables.Current_Date);
        MessageBox.Show("Successfully Added", "System Message:", MessageBoxButtons.OK, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1);
    }
    private void Btn_Browse_Click(object sender, EventArgs e)
    {
        rc.BrowseImage(UserImage, Variables.location , lbl_location);      
    }
}

public class Register

                UserImage.SizeMode = PictureBoxSizeMode.StretchImage;

您可以使用以下命令获取资源路径。

var path = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory,
                                          @"..\..\Resources","User.png"));
