用鼠标点住左键选择多个同一个界面下的Label 得到Label 的Text 在线等。

类似window桌面 用鼠标点住左键选择多个文件。

呵呵，收藏了

[fangkuai3]

我的Label是动态生成后是充满Panel。鼠标选择在Label上就不行了。可以改吗？

  private SetControlRectangle m_SetRect;
        private void Form1_Load(object sender, EventArgs e)
        {
            m_SetRect = new SetControlRectangle(this);
            m_SetRect.SetRectangel += new SetControlRectangle.SelectRectangel(m_SetRect_SetRectangel);
        }

        void m_SetRect_SetRectangel(object sneder, Rectangle e)
        {           

            string _SetText="";
            for (int i = 0; i != this.Controls.Count; i++)
            {
                if (this.Controls[i] is Label)
                {
                    if (e.IntersectsWith(this.Controls[i].Bounds))
                    {
                        _SetText += this.Controls[i].Text + "\r\n";
                    }
                }
            }

            MessageBox.Show(_SetText);
        }

我没判断是否是子控件~~你可以低归获取 用RectangleToScreen转换 然后IntersectsWith

SetControlRectangle 是 http://blog.csdn.net/zgke/archive/2008/12/12/3502920.aspx

不知道能不能帮你

参考：

private void Form1_Load(object sender, EventArgs e)
{
labellist = new List<Label>();
foreach (Control c in this.Controls)
{
if(c is Label)
{
Label l= c as Label;
l.MouseUp += new MouseEventHandler(l_MouseUp);
}
}
}
List<Label> labellist;

void l_MouseUp(object sender, MouseEventArgs e)
{

if (e.Button == MouseButtons.Left)
{

Label l = (Label)sender;
if (labellist.Contains(l))
{
l.BackColor = Color.Transparent;
labellist.Remove(l);
}
else
{
l.BackColor = SystemColors.Highlight;
labellist.Add(l);
}

}
}

我这是一个Panel里有多个多个Label 怎么鼠标按住不放 选中多个

[fangkuai3]

问3楼 h_w_king
你做的项目是什么项目？
你能写详细点吗

[xiaoyanwei2000]

修改一下3楼的
private void Form1_Load(object sender, EventArgs e)
{
m_SetRect = new SetControlRectangle(this.panel1 );
m_SetRect.SetRectangel += new SetControlRectangle.SelectRectangel(m_SetRect_SetRectangel);
}


void m_SetRect_SetRectangel(object sneder, Rectangle e)
{

string _SetText = "";

for (int i = 0; i != this.panel1.Controls.Count; i++)
{
if (this.panel1.Controls[i] is Lable)
{
if (e.IntersectsWith(this.panel1.Controls[i].Bounds))
{
_SetText += this.panel1.Controls[i].Text + "\r\n";
}
}
}

MessageBox.Show(_SetText);
}

[xiaoyanwei2000]

private void Form1_Load(object sender, EventArgs e)
{
m_SetRect = new SetControlRectangle(this.panel1 );
m_SetRect.SetRectangel += new SetControlRectangle.SelectRectangel(m_SetRect_SetRectangel);
}


void m_SetRect_SetRectangel(object sneder, Rectangle e)
{

string _SetText = "";

for (int i = 0; i != this.panel1.Controls.Count; i++)
{
if (this.panel1.Controls[i] is TextBox)
{
if (e.IntersectsWith(this.panel1.Controls[i].Bounds))
{
_SetText += this.panel1.Controls[i].Text + "\r\n";
}
}
}

MessageBox.Show(_SetText);
}

[xiaoyanwei2000]

好像3楼给的SetControlRectangle 类也有点问题吧
用鼠标拖拽矩形框只有从右上到左下能够显示值，其他方向好像不行

[fangkuai3]

2楼的那个我还没看懂呢！很多命名空间都不知道

[zgke]

对不起啊~~~ 忘记了 时间长了忘记哪个类是没有反转的~~
改了下
void m_SetRect_SetRectangel(object sneder, Rectangle e)
{
if (e.Width < 0)
{
int _X = e.X;
e.X = e.Width+e.X;
e.Width = _X;
}
if (e.Height < 0)
{
int _Y = e.Y;
e.Y = e.Height+e.Y;
e.Height = _Y;
}


string _SetText="";
for (int i = 0; i != this.Controls.Count; i++)
{
if (this.Controls[i] is Label)
{
if (e.IntersectsWith(this.Controls[i].Bounds))
{
_SetText += this.Controls[i].Text + "\r\n";
}
}
}
MessageBox.Show(_SetText);

}

SetControlRectangle 里的很多命名空间是什么啊？

[fangkuai3]

谢谢大家

改成这样
if (e.Width < 0)
{
int _X = e.X;
e.X = e.Width+e.X;
e.Width = _X - e.X;
}
if (e.Height < 0)
{
int _Y = e.Y;
e.Y = e.Height+e.Y;
e.Height = _Y - e.Y;
}
