VBNET 將字串分割,並產生字串陣列
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' === 字串切割 ===
Dim MyString = "09/02/04 4:00p 21.9 21.9 21.8 69 15.9 3.6 NE 2.15 6.3 "
Dim charSeparators() As Char = {" "c}
Dim strResult() = MyString.Trim().Split(charSeparators, StringSplitOptions.RemoveEmptyEntries)
' === 顯示 ===
For i As Integer = 0 To strResult.Length - 1
Me.TextBox1.Text += strResult(i) + Environment.NewLine
Next
End Sub
End Class

另外 微軟又有調整新的用法
Strings.Split(String, String, Int32, CompareMethod) 方法
Dim testString As String = "apple pear banana "
Dim testArray() As String = Split(testString)
' testArray holds {"apple", "", "", "", "pear", "banana", "", ""}
Dim lastNonEmpty As Integer = -1
For i As Integer = 0 To testArray.Length - 1
If testArray(i) <> "" Then
lastNonEmpty += 1
testArray(lastNonEmpty) = testArray(i)
End If
Next
ReDim Preserve testArray(lastNonEmpty)
' testArray now holds {"apple", "pear", "banana"}
