三Imges從三個網址加載，並顯示在3圖片框

Question

我想要從3 url請求3圖像，然後嘗試顯示在三個picturebox.But我有我的代碼中的問題。非常感謝答案！

 private void button1_Click(object sender, EventArgs e) 
     { 


      var request1 = WebRequest.Create("https://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Schloss_Neuschwanstein_2013.jpg/300px-Schloss_Neuschwanstein_2013.jpg"); 
      var request2 = WebRequest.Create("https://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Schloss_Neuschwanstein_2013.jpg/300px-Schloss_Neuschwanstein_2013.jpg"); 
      var request3 = WebRequest.Create("https://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Schloss_Neuschwanstein_2013.jpg/300px-Schloss_Neuschwanstein_2013.jpg"); 




     using (var response1 = request1.GetResponse()) 
     using (var response2 = request2.GetResponse()) 
     using (var response3 = request2.GetResponse()) 


     using (var stream1 = response1.GetResponseStream()) 
     using (var stream2 = response2.GetResponseStream()) 
     using (var stream3 = response2.GetResponseStream()) 


     { 
      pictureBox1.Image = Bitmap.FromStream(stream1); 
      pictureBox2.Image = Bitmap.FromStream(stream2); 
      pictureBox3.Image = Bitmap.FromStream(stream3); 

      } 

     } 

    } 
}

你可以試試這個。

private void button1_Click(object sender, EventArgs e) 
    { 
     pictureBox1.Load("http://i.imgur.com/ZkWyBo5.jpg?2"); 
     pictureBox2.Load("http://i.imgur.com/ZkWyBo5.jpg?2"); 
     pictureBox3.Load("http://i.imgur.com/ZkWyBo5.jpg?2"); 
    } 

由於使用using語句不正確，您的代碼被掛起。請記住，在使用聲明中有一個範圍。

如果你想使用你的代碼：

 private void button1_Click(object sender, EventArgs e) 
    { 

     var request1 = WebRequest.Create("http://i.imgur.com/ZkWyBo5.jpg?2"); 
     var request2 = WebRequest.Create("http://i.imgur.com/ZkWyBo5.jpg?2"); 
     var request3 = WebRequest.Create("http://i.imgur.com/ZkWyBo5.jpg?2"); 

     using (var response1 = request1.GetResponse()) 
     { 
      using (var stream1 = response1.GetResponseStream()) 
      { 
       pictureBox1.Image = Bitmap.FromStream(stream1); 
      } 
     } 
     using (var response2 = request2.GetResponse()) 
     { 
      using (var stream2 = response2.GetResponseStream()) 
      { 
       pictureBox2.Image = Bitmap.FromStream(stream2); 
      } 
     } 
     using (var response3 = request3.GetResponse()) 
     { 
      using (var stream3 = response3.GetResponseStream()) 
      { 
       pictureBox3.Image = Bitmap.FromStream(stream3); 
      } 
     } 
    }
