C# よりも、VB の方がいいんじゃない？
簡単だよ。
Public Class Form1

    Private pic As New PictureBox

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        pic.Image = My.Resources.sep_50.ToBitmap
        pic.Size = New Size(My.Resources.sep_50.Width, My.Resources.sep_50.Height)

        Controls.Add(pic)

        AddHandler Me.KeyUp, AddressOf me_Keyup

    End Sub

    Private Sub me_Keyup(ByVal s As Object, ByVal e As KeyEventArgs)
        Select Case e.KeyCode
            Case Keys.Left
                pic.Location = New Point(pic.Left - 10, pic.Top)
            Case Keys.Right
                pic.Location = New Point(pic.Left + 10, pic.Top)
            Case Keys.Up
                pic.Location = New Point(pic.Left, pic.Top - 10)
            Case Keys.Down
                pic.Location = New Point(pic.Left, pic.Top + 10)

        End Select

    End Sub
End Class

感じるところがあれば、ご自分のPGへ取り込んで下さい。
上記は、VBですが、上下左右の矢印キーでsep_50.ico が動くことを確認しました。

C# も載せます。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace GameCs
{
    public partial class Form1 : Form
    {
        private PictureBox pic = new PictureBox();
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Controls.Add(pic);

            pic.Paint += pic_Paint;
            this.KeyUp += me_Keyup;          
        }

        private void pic_Paint(Object s, PaintEventArgs e)
        {
            e.Graphics.DrawRectangle(Pens.AliceBlue,new Rectangle(10,10,40,40));
            e.Graphics.FillRectangle(Brushes.Aqua, new Rectangle(10, 10, 40, 40));
        }

        private void me_Keyup(object s, KeyEventArgs e)
        {
            switch (e.KeyCode)
            {
                case Keys.Up:
                    pic.Top = pic.Top - 10;
                    break;
                case Keys.Down:
                    pic.Top = pic.Top + 10;
                    break;
                case Keys.Left:
                    pic.Left = pic.Left - 10;
                    break;
                case Keys.Right:
                    pic.Left = pic.Left + 10;
                    break;
                default:
                    break;
            };
        }

    }
}

C#はかなり怪しいですが、一応動いているようです。

がんばってください。
