如何让C#中的图片框在visual Studio for maze设计项目中可点击？

Question

我按照本教程使用表单模板和C#在Visual Studio中创建了一个迷宫，但我不能确切地理解他是如何将图片框变成按钮的，并且能够制作一个允许用户操作图片框来创建迷宫的表单。http://www.c-sharpcorner.com/uploadfile/4a950c/solving-mazes-using-recursion/

private void createNewMaze()
{
mazeTiles = new PictureBox[XTILES, YTILES];
//Loop for getting all tiles
for (int i = 0; i < XTILES; i++)
{
    for (int j = 0; j < YTILES; j++)
    {
        //initialize a new PictureBox array at cordinate XTILES, YTILES
        mazeTiles[i, j] = new PictureBox();
        //calculate size and location
        int xPosition = (i * TILESIZE) + 13; //13 is padding from left
        int yPosition = (j * TILESIZE) + 45; //45 is padding from top
        mazeTiles[i, j].SetBounds(xPosition, yPosition, TILESIZE, TILESIZE);
        //make top left and right bottom corner light blue. Used for start and finish
                if ((i == 0 && j == 0) || (i == XTILES - 1 && j == YTILES - 1))
                    mazeTiles[i, j].BackColor = Color.LightBlue;
                else
                {
                    //make all other tiles white
                    mazeTiles[i, j].BackColor = Color.White;
                    //make it clickable
                    EventHandler clickEvent = new EventHandler(PictureBox_Click);
                    mazeTiles[i, j].Click += clickEvent; // += used in case other events are used
                }
                //Add to controls to form (display picture box)
                this.Controls.Add(mazeTiles[i, j]);
            }
        }
    }

我也创建了这个方法，但我只有一个普通的图片框和两个按钮。

private void PictureBox_Click(object sender, EventArgs e)
 {
        ((PictureBox)sender).BackColor = currentColor;
    }

你的事件处理程序没问题，但是如果你把颜色改成当前的颜色，它不会显示任何变化。

尝尝这个,

private void PictureBox_Click(object sender, EventArgs e)
 {
   pictureBox.BackColor = Color.Brown;
 }
