Windows Form Application "How do I increase the size of the button when the mouse hovers over t-CodePudding

private void Form1_Load(object sender, EventArgs e)
    {
        if (MouseMove == button1;)
        {

I couldn't find how to write code

Use the MouseEnter event to capture the mouse cursor hovering over the button borders,
and the MouseLeave event to detect when the cursor leaves the button borders, in order to return it to its original size.

Here is one way to implement such functionality:

private Size OriginalButtonSize;
private Size HoveredSize;
private void Form1_Load(object sender, EventArgs e)
{
    OriginalButtonSize = this.button1.Size;
    HoveredSize = new Size(OriginalButtonSize.Width   30, OriginalButtonSize.Height   30);
}

private void button1_MouseEnter(object sender, EventArgs e)
{
    button1.Size = HoveredSize;
}

private void button1_MouseLeave(object sender, EventArgs e)
{
    button1.Size = OriginalButtonSize;
}

Output:

You can use this code:

        private void button1_MouseHover(object sender, EventArgs e)
    {
        button1.Width = 100;
        button1.Height = 70;
    }

if you want to set size to the previous size after leaving the mouse, you can use this (for example it was 60 and 30 at first place):

    private void button1_MouseLeave(object sender, EventArgs e)
    {
        button1.Width = 60;
        button1.Height = 30;
    }
