Question

i ve 6 label controls in a form: label1, label2...label6. How to refer to the control in a loop like this:

for (i=1;i<=6;i++) {
   label[i].text = ...;
}

谢谢。

Answer 1

让我们假设这种控制是WinForms,而你的“实验室”是控制——<>Form有Controls 财产,即与该集装箱有关的控制,因此,我们应当能够利用Linq来质疑这一点,掌握我们想要的那种控制,然后将其er为:



using System.Linq;

var labels = from control in Controls where control is Label select control;

for (i = 1; i <= controls.Count; i++)
{
   labels[i].text = i.ToString();
}


A little rough, but you aren t very specific - it should be a decent starting point if nothing else.

EDIT:

韩文,我认为我需要时间来研究,并读到<条码>。 表格:Controls 在林克(以这种直截了当的方式,至少是这样),作为一种替代办法,这应当有助于:

private List<Label> GetLabels()
{
    var result = new List<Label>();
    foreach (var control in Controls)
    {
        if (control is Label)
        {
            result.Add(control as Label);
        }
    }
    return result;
}


甚至可以笼统地考虑上述方法,但可以:

var labels = GetLabels();
for (int i = 0; i <= labels.Count; i++)
{
    labels[i].Text = i.ToString();
}

Answer 2

Try,

Label []labels={Label1,Label2,Label3};

Answer 3

这里还有另一种方式:

for (int n = 1; n < 4; n++)
{
    Control[] Temp = Controls.Find("Label" + n, false);
    Temp[0].Text = n.ToString();
}

Answer 4

你们可以执行这样的行动:

    int y = 0;
    int index = 0;

    Label[] labels = new Label[6];

    foreach (Student std in StudentList)
    {
            labels[index] = new Label();

            labels[index].Text = std.Name;

            labels[index].ForeColor = Color.Red;

            labels[index].Location = new Point(0, y);

            labels[index].Size = new Size(50, 12);

            y = y + 10;
            ++index;
    }

    // Add the Label control to the form.
    mPanel.Controls.AddRange(labels);
