OK这是我所做的,并且垂直设置的值将复制到标签中但水平。并且只有一列/行。
public partial class Form1 : Form
{
private Label l;
private Button bStart;
private TextBox txtVnes;
private Label[] pole;
public Form1()
{
InitializeComponent();
bStart = new Button();
bStart.Location = new Point(240, 165);
bStart.Width = 75;
bStart.Height = 25;
bStart.Text = "START";
txtVnes = new TextBox();
txtVnes.Location = new Point(240, 10);
txtVnes.Width = 160;
txtVnes.Height = 130;
txtVnes.Multiline = true;
int a = 0;
pole = new Label[42];
for (int i = 1; i <= 6; i++)
{
for (int j = 1; j <= 7; j++)
{
l = new Label();
l.Name = "label" + i.ToString() + j.ToString();
l.Text = "Z";
l.Width = 20;
l.Height = 20;
l.TextAlign = ContentAlignment.MiddleCenter;
l.Parent = this;
l.BackColor = Color.FromArgb(100, 149, 237);
l.Location = new Point(10 + (j - 1) * 25, 15 + (i - 1) * 25);
pole[a] = l;
this.Controls.Add(l);
a++;
}
}
this.Controls.Add(bStart);
this.Controls.Add(txtVnes);
bStart.Click += new EventHandler(bStart_Click);
}
private void bStart_Click(object sender, EventArgs e)
{
Regex regex = new Regex(@"^(\s)*(\d ){6}\d(\s)*$");
bool isValid = true;
string[] ts = txtVnes.Text.Split(new string[] { "\r\n" },
StringSplitOptions.RemoveEmptyEntries);
if (ts == null || ts.Length < 1 || ts.Length > 6)
{
MessageBox.Show("Not valid");
}
else
{
foreach (string t in ts)
{
if (regex.IsMatch(t) == false)
{
MessageBox.Show("Not valid");
break;
}
}
}
if (isValid)
{
for (int i = 0; i < 6; i++)
{
if (i < ts.Length && regex.IsMatch(ts[i]))
{
pole[i].Text = ts[i];
}
else
{
pole[i].Text = "not valid";
}
}
}
}
所以这就是问题所在:当我点击按钮bStart时,只复制一个值并从标签数组中替换为一个labe。
这应该是这样的:在用户点击按钮bStart之后,文本框txtVnes中的所有值都应该复制到标签数组中的每个标签中。所有标签都有文本“Z”,点击按钮后,应使用文本框txtVnes中的值更改它们。正如您所看到的,我使用l.Text = txtVnes.Text;
来复制值,但它不起作用。如果你能帮助我,我感激不尽,谢谢!
答案 0 :(得分:0)
您始终设置相同标签l
的文字。由于您的标签位于数组pole
中,因此您应将文本设置为连续的pole
索引。
我想要开头的所有有效文本:
string[] ts = txtVnes.Text.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
int k = 0;
for (int i = 0; i < ts.Length && k < 6; i++) {
if (IsValid(ts[i])) { // Where IsValid is a method containing your validation logic.
pole[k++].Text = ts[i];
}
}
// Fill remaining labels
for (int i = k; i < 6; i++) {
pole[i].Text = "not valid";
}
或者,如果你想混合使用vaild和无效文本:
string[] ts = txtVnes.Text.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
for (int i = 0; i < 6; i++) {
if (i < ts.Length && IsValid(ts[i])) { // Where IsValid is a method containing your validation logic.
pole[i].Text = ts[i];
} else {
pole[i].Text = "not valid";
}
}
请注意,数组索引从0开始,而不是从1开始。
编辑#2:
IsValid
方法如下所示:
private static Regex regex = new Regex(@"^(\s)*(\d ){6}\d(\s)*$");
private static bool IsValid(string s)
{
return regex.IsMatch(s);
}
要在评论中回答您的问题:是的,我上面的示例必须放在bStart_Click
中。
表单构造函数中还有另一个错误。 this.Controls.Add(l);
应放在内部for循环中,紧跟在pole[a] = l;
之后,否则表单上只会显示一个标签。
最后,在实施并分析了您的代码之后,我得出的结论是,您希望能够将以下格式的文本输入到文本框中,然后将数字放入相应的标签中:
1 2 3 4 5 6 7
2 3 4 6 7 8 0
0 1 2 6 6 6 7
1 2 3 4 5 6 7
2 3 4 6 7 8 0
0 1 2 6 6 6 7
完整代码应如下所示:
public partial class Form1 : Form
{
private Button bStart;
private TextBox txtVnes;
private Label[] pole;
public Form1()
{
InitializeComponent();
bStart = new Button();
bStart.Location = new Point(240, 165);
bStart.Width = 75;
bStart.Height = 25;
bStart.Text = "START";
bStart.Click += new EventHandler(bStart_Click);
this.Controls.Add(bStart);
txtVnes = new TextBox();
txtVnes.Location = new Point(240, 10);
txtVnes.Width = 160;
txtVnes.Height = 130;
txtVnes.Multiline = true;
this.Controls.Add(txtVnes);
int a = 0;
pole = new Label[42];
for (int i = 1; i <= 6; i++) {
for (int j = 1; j <= 7; j++) {
var l = new Label();
l.Name = "label" + i.ToString() + j.ToString();
l.Text = "Z";
l.Width = 20;
l.Height = 20;
l.TextAlign = ContentAlignment.MiddleCenter;
l.Parent = this;
l.BackColor = Color.FromArgb(100, 149, 237);
l.Location = new Point(10 + (j - 1) * 25, 15 + (i - 1) * 25);
pole[a] = l;
this.Controls.Add(l);
a++;
}
}
}
private void bStart_Click(object sender, EventArgs e)
{
string[] ts = txtVnes.Text.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries);
int row = 0;
for (int i = 0; i < ts.Length && row < 6; i++) {
if (LineIsValid(ts[i])) {
for (int col = 0; col < 7; col++) {
pole[row * 7 + col].Text = ts[i][2 * col].ToString();
}
row++;
}
}
// Fill remaining labels
for (; row < 6; row++) {
for (int col = 0; col < 7; col++) {
pole[row * 7 + col].Text = "Z";
}
}
}
private static Regex regex = new Regex(@"^(\s)*(\d ){6}\d(\s)*$");
private static bool LineIsValid(string line)
{
return regex.IsMatch(line);
}
}
bStart_Click中还需要两个嵌套循环。一行用于行,一行用于列。
