asp.net - 难以将图像存储在我的项目的图像文件夹中

Question

我想将图像存储在我项目的根文件夹中。但是图像存储在管理文件夹->图像中。这是我的C# 代码：此代码写在管理面板 -> AddProducts 文件中。

protected void Button3_Click(object sender, EventArgs e)
{
    FileUpload FileUpload1 = FileImage;
    string virtualFolder = "images/";
    string img = "images/";
    string f = (DateTime.Now.GetHashCode()).ToString(); ;
    string physicalFolder = Server.MapPath(virtualFolder);
    FileUpload1.SaveAs(physicalFolder + f + FileUpload1.FileName);        
    Image1.Visible = true;
    Image1.ImageUrl = virtualFolder + f + FileUpload1.FileName;
    string path = img + f + FileUpload1.FileName;
    TextBox4.Text = path;   
}

~使用Server.mappath 时始终使用符号

  protected void Button3_Click(object sender, EventArgs e)
    {
        FileUpload FileUpload1 = FileImage;
        string virtualFolder = "~/images/";
        string img = "~/images/";
        string f = (DateTime.Now.GetHashCode()).ToString(); ;
        string physicalFolder = Server.MapPath(virtualFolder);
        FileUpload1.SaveAs(physicalFolder + f + FileUpload1.FileName);
        Image1.Visible = true;
        Image1.ImageUrl = virtualFolder + f + FileUpload1.FileName;
        string path = img + f + FileUpload1.FileName;
        TextBox4.Text = path;
    }
