How do I resize a Windows Forms form in C#?

Question

I am making a Windows Forms application. I want the forms height to increase after a button is pressed. How do I do this?

Answer 1

You can just increase the form height value by a specified amount on the button click:

private void button1_Click(object sender, EventArgs e)
{
    int amountToIncrease = 10;
    this.Height += amountToIncrease;
}    

Answer 2

this.Size = new Size(175, 125);

or

this.ClientSize = new Size(175, 125);

From MSDN: The size of the client area of the form is the size of the form excluding the borders and the title bar.

Answer 3

Use the Height property. For instance:

this.Height = newHeight;
