将文字插入标签 [英] insert text to label
问题描述
你好！
我想要的是，对于每个:1,2,3,4循环，它都会在之前添加一个数字，例如其计数，但会停在4.所以:1,2,3,4,11,12,13 ，14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133，134,141,142,143,144,211 ........
就像盘点一样，但用4个数字代替9.
而且我希望它像这样工作，每次我按下按钮时，我都希望它显示一个新的数字.
Hello!
What I want is that, for each time that : 1,2,3,4 loop it will ad a number before, like its counting but it stops at 4. so: 1,2,3,4,11,12,13,14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133, 134,141,142,143,144,211........
just like counting but with 4 numbers instead of 9.
And i want it to work like this, for each time that i press the button i want it to show a new number.
String[] text = { "1", "2", "3", "4" };
int count = 0;
private void button1_Click(object sender, EventArgs e)
{
if (count == text.Length)
{
count = 0;
}
label1.Text = text[(count % text.Length)];
count++;
}
谢谢！
Thank you!
推荐答案
为什么不随便去:
Why not just go:
myLabel.Text = "My new text: " + myLabel.Text;
不，实际上我发现它不起作用！...就我而言-euhiemf 31分钟前".
那为什么不呢?什么无效"?
"No, actually i found out that it doesn''t work!... for my thing - euhiemf 31 mins ago"
So why not? What "doesn''t work"?
String[] text = { "1", "2", "3", "4" };
int count = 0;
private void button1_Click(object sender, EventArgs e)
{
if (count == text.Length)
{
count = 0;
}
label1.Text = text[(count % text.Length)];
count++;
}

好的，这是一个代码片段.看来与您的问题无关.
您的片段仅在每次按下按钮时才将标签文本设置为不同的值.如果不打算这样做，那意味着要做什么? :laugh:
我想要的是，对于每次1,2,3,4循环，它都会在之前添加一个数字，例如其计数，但会停在4.因此:1,2,3,4,11， 12,13,14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133，134,141,142,143,144,211 ..... ;)-euhiemf 25分钟前"
哦，这就是全部:
您不能这么简单地做到这一点，因为您没有零可玩！所以.有点复杂...

Ok, so it''s a code fragment. It appears to have nothing to do with your question.
Your fragment just sets a label text to a different value each time a button is pressed. If it isn''t intended to do that, what is it meant to do? :laugh:
"what i want is that for each time that : 1,2,3,4 loop it will ad a number before, like its counting but it stops at 4. so: 1,2,3,4,11,12,13,14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133, 134,141,142,143,144,211........ just like counting but with 4 numbers instead of 9. ;) - euhiemf 25 mins ago"
Oh, is that all:
You can''t do that quite so simply, you have no zero to play with! So. it gets a bit complex...
int[] currentValue = new int[3] { 0, 0, 0 };
private void button1_Click(object sender, EventArgs e)
{
for (int i = 0; i < currentValue.Length; i++)
{
if (currentValue[i] != 4)
{
currentValue[i]++;
break; // No need to move next digit.
}
else
{
// Move the next highest digit.
currentValue[i] = 1;
}
}
string s = "";
for (int i = currentValue.Length - 1; i >=0; i--)
{
s += currentValue[i].ToString();
}
label1.Text = s;
这只能处理三个四边形(不能再叫数字，"dig"从基数10开始)，第一次按会将标签设置为"001"，但是我要给您做点工作！
This only handles three quadits (Can''t call then digits, the "dig" comes from base ten) and the first press will set the label to "001", but I have to leave you some work!
显然您不能使用SelectionStart属性.
插入应该可以工作，它是一个String方法.
为什么不简单
Obviously you can''t use the SelectionStart property.
The Insert should work though, it''s a String method.
Why not simply
label1.Text = "labe" + label1.Text;
?
您是否看到过:转换到任何基础 [
?
Did you see this : Convert to any base[^]
Change your array to
string quat = IntToString(42,
new char[] { ''0'', ''1'', ''2'', ''3'', ''4'' };
将此函数放在您的代码中:
Put this function in your code :
public static string IntToString(int value, char[] baseChars)
{
string result = string.Empty;
int targetBase = baseChars.Length;
do
{
result = baseChars[value % targetBase] + result;
value = value / targetBase;
}
while (value > 0);
return result;
}
现在重写您的函数:
Now rewrite your function :
private void button1_Click(object sender, EventArgs e)
{
label1.Text = IntToString(count, quat);
count++;
}
足够接近，未经测试，但大致正确:)
Close enough, not tested but about right :)
