如何分隔字符串中的每个字符并将每个字符放置在单独的标签中? [英] How can I separate each character in a string and place each character in a separate label?

问题描述

您好，我正在使用WinForms.

我的目标是拆分一个由18个字符组成的字符串，以便每个字符都被视为一个单独的值.

例如，如果232223232223323222是我的字符串，则需要将其拆分为18个单独的字符串:
2
3
2
2
2
3
2
....依此类推.

如何实现?

我尝试了几种方法:

Hello, I am using using WinForms.

My objective is to split a string of 18 characters so that each character is seen as a separate value.

For example, if 232223232223323222 is my string, I need to split it into 18 separate strings:
2
3
2
2
2
3
2
....and so on.

How can this be achieved?

I have tried several methods:

String a = 2223232223323222;
            a.ToCharArray();

            richTextBox1.Text = richTextBox1.Text + a;</pre>

和

and

string input = 2223232223323222;
            double parts = 1;
            int k = 0;
            var output = input.ToLookup(c => Math.Floor(k++ / parts))
                .Select(b => new String(b.ToArray()));

            totalres.Text = output.ToString();

老实说，我什至不知道自己在做什么.

每个值都有自己的字符串(18个字符串)之后，如何将每个值放入自己的标签中?

我只要求您的解释中的详细程度为中高.

谢谢！

To be honest, i''m not even sure what I am doing.

After each value is its own string (18 strings) how can I place each one into its own label?

I only request that level of detail in your explanations is medium-high.

Thank you!

推荐答案

这是怎么回事:

What''s wrong with this:

int top = 0;
int gap = 4; //for example...
foreach (char ch in a) {
    Label label = new Label(); 
    label.Location = new Point(0, top);
    label.Text = ch.ToString();
    parent.Controls.Add(label);
    top += gap + label.Height;
}

由于OP仍然在做……谁知道呢，我在位置计算中加入了细节.假设所有内容都放在适当大小的面板上，那么最左上角的位置是{0，0}.

As OP still does… who knows what, I added to detail with calculation of position. Let''s assume it all is put on some panel of appropriate size, so left-topmost position is {0, 0}.

你好

有一个Panel和:

Hello

Have a Panel and:

string a = "2223232223323222";

char[] chars = a.ToCharArray();
for (int i = 0; i < chars.Count(); i++)
{
    Label l = new Label();

    l.Text = chars[i].ToString();
    this.MyPanel.Controls.Add(l);
    l.Top = i * l.Height;
}

或者您也可以不使用Panel:

or you can do it without Panel:

this.Controls.Add(l);

如果我是你，我将创建一种方法来找出Label s
的准确坐标

If I were you, I would create a method to figure out the accurate coordinate for Labels

private void Form1_Load(object sender, EventArgs e)
{
    string a = "2223232223323222";

    char[] chars = a.ToCharArray();
    for (int i = 0; i < chars.Count(); i++)
    {
        Label l = new Label();

        l.Text = chars[i].ToString();
        this.MyPanel.Controls.Add(l);
        SetCoordinate(l, i);
    }

}
private void SetCoordinate(Label lable, int i)
{
    // some code to computing
}

但是:
如果Form中有许多Label，请标记它们.
将其标签设置为0、1、2、3和...
然后:

But:
If You have many Labels in your Form, then tag them.
Set their Tags to 0, 1, 2, 3 and ...
Then:

private void Form1_Load(object sender, EventArgs e)
{
    string a = "2223232223323222";

    char[] chars = a.ToCharArray();
    for (int i = 0; i < chars.Count(); i++)
    {
        Label l = FindLabel(i);
        if (l == null)
            continue;
        l.Text = chars[i].ToString();
    }

}
private Label FindLabel(int i)
{
    foreach (Control c in this.Controls)
    {
        if (c.Tag == null)
            continue;

        int k = 0;
        if (!int.TryParse((c.Tag).ToString(), out k))
            continue;

        if (c is Label && k == i)
            return (Label)c;
    }

    return null;
}
