我从我的项目src文件中抓取了imageicon,如下所示:

 icon = new ImageIcon(ViewDetailsV.class.getResource("/brandnew/images/male_avatar.jpg"));

然后我想放入这一行,以便调整大小到标签的大小:

lblPhotoField.setIcon(new ImageIcon(ScaledImage(icon, lblPhotoField.getWidth(), lblPhotoField.getHeight()));

但我需要"图标"作为图像,而不是图像图像,因为ScaledImage采用Image参数而不是ImageIcon.

 private Image ScaledImage(Image img, int w, int h){
    BufferedImage resizedImage = new BufferedImage(w,h,BufferedImage.TYPE_INT_RGB);

    Graphics2D g2 = resizedImage.createGraphics();
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
    g2.drawImage(img, 0,0,w,h,null);
    g2.dispose();
    return resizedImage;
}

是的,我确实尝试将返回值更改为ImageIcon,但它给了我错误.所以我现在专注于如何将ImageIcon转换为Image,这样我就可以将它放在方法行中,获取图标并将我的标签设置为:

 lblPhotoField.setIcon(icon);

我想计算字符串中的单词数。就像如果给定一个字符串：

string str = "Hello! How are you?";

那么输出将是：

Number of words in string “Hello! How are you?” is 4.

我正在使用 for 循环，这些是我当前的代码。

    string wordCountStr = "";
    int noOfWords = 0;
    private void btn_Computate4_Click(object sender, EventArgs e)
    {
        wordCountStr = tb_Qns4Input.Text.ToString(); //tb_Qns4Input is a textbox.

        for (int i = 0; i< wordCountStr.Length; i++)
        {
            //I don't know how to code here.
        }

        lbl_ResultQns4.Text = "Number of words in string " + wordCountStr + " is " + noOfWords;
    }

哦，是的，我正在使用 …
