VB.net - 如何使用“分割字符串”后跟一个空格作为分隔符

发布于 2024-12-26 11:17:33 字数 342 浏览 6 评论 0原文

我有一个从 xml 文件返回的字符串，看起来与此类似，

name1="test 1" name2="test2" name3="test 3"

我想将其拆分为 key=value 的 3 个元素。我不能只使用空格进行拆分，因为我的某些值可能包含空格，例如 test 1。

因此，我想在空格之前使用 " 来拆分字符串。我尝试了很多变体，但不能找出正确的语法来指定我的分割字符是一个“后跟一个空格。例如，我尝试过 text.split({""" "}) 但它返回由 " 分割的元素并忽略 " 后面的空格。

不应该这么困难。有人可以帮我正确的语法吗？

原文

I have an string that is returned from an xml file and looks similar to this

name1="test 1" name2="test2" name3="test 3"

I want to split this into 3 elements of key=value. I can't just split using a space because some of my values may contain spaces, e.g., test 1.

So, I'd like to split the string using the " before the space. I've tried many variations but can't figure out the correct syntax to specify that my split characters are a " followed by a space. For instance, I've tried text.split({""" "}) but that returns elements split by " and ignores the space after the ".

It shouldn't be this difficult. Can someone please help me with the correct syntax?

试试这个：

text.Split(New String() {""" "}, StringSplitOptions.RemoveEmptyEntries)

更新

由于这将删除除最后一个元素之外的所有元素中的尾随“，因此在处理结果时需要考虑到这一点。

下面是一个示例：

    Dim sValue As String = "name1=""test 1"" name2=""test2"" name3=""test 3"""

    Dim asValues As String() = sValue.Split(New String() {""" "}, StringSplitOptions.RemoveEmptyEntries)

    For Each sKVP As String In asValues
        If Not sKVP.EndsWith("""") Then
            sKVP &= """"
        End If
        Console.WriteLine(sKVP)
    Next

以及结果输出：

name1="test 1"
name2="test2"
name3="test 3"

Try this:

text.Split(New String() {""" "}, StringSplitOptions.RemoveEmptyEntries)

Update

Since this will remove the trailing " in all but the last element, you need to account for this when processing the results.

Here is an example:

    Dim sValue As String = "name1=""test 1"" name2=""test2"" name3=""test 3"""

    Dim asValues As String() = sValue.Split(New String() {""" "}, StringSplitOptions.RemoveEmptyEntries)

    For Each sKVP As String In asValues
        If Not sKVP.EndsWith("""") Then
            sKVP &= """"
        End If
        Console.WriteLine(sKVP)
    Next

and the resultant output:

name1="test 1"
name2="test2"
name3="test 3"

您可以使用 LINQ 创建 Dictionary(Of String, String)：

Dim q = From item In value.Split({""" "}, StringSplitOptions.RemoveEmptyEntries)
        Select item.Split("="c)

Dim dict = q.ToDictionary(Function(i) (i(0)),
                          Function(i) (i(1)))

_{注意：这不是自动防故障的，如果有重复的键，您'会得到一个例外。}

You could use LINQ to create the Dictionary(Of String, String):

Dim q = From item In value.Split({""" "}, StringSplitOptions.RemoveEmptyEntries)
        Select item.Split("="c)

Dim dict = q.ToDictionary(Function(i) (i(0)),
                          Function(i) (i(1)))

_{Note: this is not fail-safe, f.e. if there are repeating keys, you'll get an exception.}
