尝试：

Try:

Image im = new Bitmap(path);

string path = Assembly.GetExecutingAssembly().GetName().CodeBase;

char[] address = path.ToCharArray();

string final_address = "";

for (int i = 0; i < address.Length; i++)
{
    final_address += address[i];
}

Image img = new Bitmap(final_address + "1.jpg");

pictureBox1.Image = img;
