C#控件位置的互换

我互换以后总是他自己就变回去了 是怎么回事。
int a = pictureBox1.Location.X;
int b = pictureBox1.Location.Y;

int a1 = pictureBox2.Location.X;
int b1 = pictureBox2.Location.Y;
if (textBox1.Text == "1" && textBox2.Text == "2")
{
pictureBox1.Location = new System.Drawing.Point(a1, b1);
pictureBox2.Location = new System.Drawing.Point(a, b);
}

private void button4_Click(object sender, EventArgs e)
{
int a = pictureBox1.Location.X;
int b = pictureBox1.Location.Y;

int a1 = pictureBox2.Location.X;
int b1 = pictureBox2.Location.Y;

int a2 = pictureBox3.Location.X;
int b2 = pictureBox3.Location.Y;

if (textBox1.Text == "1" && textBox2.Text == "2")
{
pictureBox1.Location = new System.Drawing.Point(a1, b1);
pictureBox2.Location = new System.Drawing.Point(a, b);
}

if (textBox1.Text == "1" && textBox2.Text == "3")
{
pictureBox1.Location = new System.Drawing.Point(a2, b2);
pictureBox3.Location = new System.Drawing.Point(a, b);
}

你的picturebox是前台添加的还是后台自动生成的？ 如果是前台添加的 你的这段代码在页面提交后就没用了。。。

估计你又重新triger 了一次event, 于是他们就换回去了．．． 把代码再贴完整点

我以前做过一个贪吃蛇,蛇不能碰到障碍物,我想和你需要的情况类似 要用到控件的几个位置属性,location(顶点坐标),width,heigth,left(location.x),right(location.x+width),top(location.y),bottom(location.y+heigth) 先拖一个panel1 加个方法 private bool istouch(control c) { foreach (control con in this.panel1.controls) {//如果在这个范围内,表示此控件会存在覆盖 if (c.right >= con.left && c.left <= con.right && c.bottom >= con.top && c.top <= con.bottom) return true; } return false; } 如下是测试代码: button b = new button(); b.location = new point(20,50);//左上角顶点坐标 b.width = 50;//宽 b.height = 50;//高 b.text = "test"; if (!istouch(b))//如果不会覆盖,添加到panel { this.panel1.controls.add(b); }
