c# - 如何将值拆分为 2 个值

Question

像这样的用户输入

textbox1.text = 01/02/03/......

我想像这样在3个文本框中分别显示值

在"/"它应该移动到下一行之后

txt1.text =  01
    txt2.text = 02
   txt3.text =  03
    ....

这该怎么做。

需要vb.net代码帮助

Answer 1

选项1

如果总是 3 个文本框，您可以为每个文本框编写静态代码，如下所示：

'EDIT: This code now checks for the existence of a second or third value to avoid
'out of bounds errors
Dim originalValue As String = "01/02/03"
Dim splitBySlash As String() = originalValue.Split("/")

txt1.Text = splitBySlash(0)
If splitBySlash.Length > 1 Then txt2.Text = splitBySlash(1)
If splitBySlash.Length > 2 Then txt3.Text = splitBySlash(2)

选项 2

如果基于斜杠的文本框数量可变，则必须在运行时创建它们并将它们添加到父控件，如下所示：

'You can enter as many (or few) slashes as you like in this code, it will automatically
'adjust the text boxes created as necessary.
Dim originalValue As String = "01/02/03" 'could go on like /04/05/etc
Dim splitBySlash As String() = originalValue.Split("/")

For Each value As String In splitBySlash
    Dim newTxt As New TextBox()
    newTxt.Text = value

    yourParentControl.Controls.Add(newTxt)
Next

Answer 2

试试这个：

string rockString =  "01/02/03/";
string[] words = rockString.Split('/');
foreach (string word in words)
    {
      Console.WriteLine(word);
     }

正如你在评论中问的

在不同的文本框中

textbox1.text = words[0]; //textbox1.text="01";
    textbox2.text = words[2]; //textbox2.text="02";
    textbox3.text = words[3]; //textbox3.text="03";

在同一个文本框中

 textbox1.text = words[0]+words[1]+words[2];

Answer 3

尝试使用String.Split或 Regex.Split

Dim value As String = "01//02//03//" 
Dim lines As String() = Regex.Split(value, "//") 
For Each line As String In lines    
Console.WriteLine(line) 
Next
