将图像显示为 Windows 窗体

Question

I wanted to display an image to the windows forms, but i already did this and the image did not come out.

Where did I go wrong?

Here is the code:

private void Images(object sender, EventArgs e)
{
    PictureBox pb1 = new PictureBox();
    pb1.Image = Image.FromFile("../SamuderaJayaMotor.png");
    pb1.Location = new Point(100, 100);
    pb1.Size = new Size(500, 500);
    this.Controls.Add(pb1);
}

Answer 1

Here ( http://www.dotnetperls.com/picturebox ) there 3 ways to do this:

• Like you are doing.

• Using ImageLocation property of the PictureBox like:

   private void Form1_Load(object sender, EventArgs e) { PictureBox pb1 = new PictureBox(); pb1.ImageLocation = "../SamuderaJayaMotor.png"; pb1.SizeMode = PictureBoxSizeMode.AutoSize; }

• Using an image from the web like:

   private void Form1_Load(object sender, EventArgs e) { PictureBox pb1 = new PictureBox(); pb1.ImageLocation = "http://www.dotnetperls.com/favicon.ico"; pb1.SizeMode = PictureBoxSizeMode.AutoSize; }

And please, be sure that "../SamuderaJayaMotor.png" is the correct path of the image that you are using.

Answer 2

There could be many reasons for this. A few that come up quickly to my mind:

1. Did you call this routine AFTER InitializeComponent() ?
2. Is the path syntax you are using correct? Does it work if you try it in the debugger? Try using backslash (\\) instead of Slash (/) and see.
3. This may be due to side-effects of some other code in your form. Try using the same code in a blank Form (with just the constructor and this function) and check.

Answer 3

I display images in windows forms when I put it in Load event like this:

    private void Form1_Load( object sender , EventArgs e )
    {
        pictureBox1.ImageLocation = "./image.png"; //path to image
        pictureBox1.SizeMode = PictureBoxSizeMode.AutoSize;
    }

Answer 4

private void Form1_Load(object sender, EventArgs e)
    {
        PictureBox pb = new PictureBox();
        pb.Location = new Point(0, 0);
        pb.Size = new Size(150, 150);
        pb.Image = Image.FromFile("E:\\Wallpaper (204).jpg");
        pb.Visible = true;
        this.Controls.Add(pb);
    }
