对路径的访问被拒绝asp.net

Question

我试图用这个代码从SQL数据库中获取的图像，并显示在Image1 ASP的控制：

cn.Open(); 
    SqlCommand cm = new SqlCommand("select * from ImageCollection where img_id='" + DropDownList1.SelectedItem.ToString() + "'", cn); 
    SqlDataAdapter da = new SqlDataAdapter(cm); 
    SqlDataReader dr = cm.ExecuteReader(); 
    try 
    { 
     if (dr.Read()) 
     { 

      string image1 = Convert.ToString(DateTime.Now.ToFileTime()); 
      FileStream fs1 = new FileStream(image1, FileMode.CreateNew, FileAccess.Write); 
      byte[] bimage1 = (byte[])dr["passport_photo"]; 
      fs1.Write(bimage1, 0, bimage1.Length - 1); 
      fs1.Flush(); 
      Image1.ImageUrl = "~/images/"+DropDownList1.SelectedItem.ToString(); 
     } 
     dr.Close(); 
     cn.Close(); 
    } 
    catch (Exception ex) 
    { 
     throw ex; 
    } 

但我结束了与此：

访问路径'C：\ Program Files（x86）\ Common Files \ Microsoft Shared \ DevServer \ 10.0 \ 130301775684384514'被拒绝。

如何在不改变整个代码（方式）的情况下克服这一点。

Answer 1

string base64String = Convert.ToBase64String(bytes, 0, bytes.Length); 
Image1.ImageUrl = "data:image/png;base64," + base64String;
