Well what I want to do is the generation of several boxes of images in my application of C #, in a few words a history of the images uploaded to my application. I currently have the following code:

Image Generation Code (Does not work).

    var directorio = new System.IO.DirectoryInfo(@"..\..\Imagenes\Imagenes_Modal\Usuario\Enero");
    PictureBox[] pics = new PictureBox[1000];
    for (int i=0;i<directorio.GetFiles().Length;i++) {
        pics[i] = new PictureBox();
        pics[i].Location = new Point(50,50);
        pics[i].Name = "pic" + i;
        pics[i].Size = new Size(300, 75);
        pics[i].ImageLocation = @"..\..\Imagenes\Imagenes_Modal\Usuario\Enero\Enero0.jpg";
    }

The above code in theory should create the images, in this case 3 images in your picturebox, I know that it would be emplamaria because they would be the same size and in the same location, that I intend to modify it, but at the moment it does not generate me not a single image, the winforms where they should be generated comes out in gray with nothing and those instructions are in the winform's constructor.

Remember that you must add the instance of PictureBox to the collection of form :

var directorio = new System.IO.DirectoryInfo(@"..\..\Imagenes\Imagenes_Modal\Usuario\Enero");

foreach (var file in directorio.GetFiles()) 
{
    PictureBox pic = new PictureBox();
    pic.Location = new Point(50,50);
    pic.Name = "pic" + i;
    pic.Size = new Size(300, 75);
    pic.ImageLocation = file;

    this.Controls.Add(pic);
}

In the last line the this will be the same form where the control is added, if you want to do it against a Panel or another control you can also.

In addition you do not need a array of PictureBox , you can go creating them and adding them to form .
