当点击窗体1的按钮，窗体2就出现在窗体1的左边：

 

窗体1public partial class Form1 : Form{public Form1(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){Form2 f = new Form2(this.Location.X+this.Width,this.Location.Y);//窗体2出现在左还是右，在new Form2（）输入参数f.Show();}}窗体2public partial class Form2 : Form{int x = 0; int y = 0;public Form2(int x,int y){InitializeComponent();this.x = x;this.y = y;}private void Form2_Load(object sender, EventArgs e){this.Location = new Point(x, y);}}
