Question

在我的网站上，我有一个文本框，允许用户输入一组这样的数字：

(118,38,137,15,156,14,157,36,152,49,142,57)

如何将这些数字存储在如下数组中？：

[118    38    137   15    156    14    157    36    152    49    142    57]

Answer 1

使用Split方法：

yourString = yourString.Substring(1, yourString.Length - 2) ' Trim parentheses.
Dim result As String() = yourString.Split(","c)

Split方法有几个重载，具体取决于目的。我在这里选择了最简单的，只需要一个Character参数，在本例中为","c，一个逗号。

Answer 2

您可以使用正则表达式：

Dim str As string = "(118,38,137,15,156,14,157,36,152,49,142,57)"
Dim matches As MatchCollection = New Regex(@"\d+").Matches(str)
Dim ints As Integer() = New Integer(matches.Count - 1) }
Dim i as Integer
For i = 0 To ints.Length - 1
    ints[i] = int.Parse(If(matches.Item(i).Value <> Nothing, _
                           a.Item(i).Value, "").ToString())
Next

请参阅String.Split

myArray = "118,38,137,15,156,14,157,36,152,49,142,57".Split (",")
