Is there an equivalent to String.Split that returns a generic list?
提问by Herb Caudill
I'd like to do something like this:
我想做这样的事情：
Dim Foo as String = "a,b,c,d,e"
Dim Boo as List(of String) = Foo.Split(","c)
Of course Foo.Splitreturns a one-dimensional array of String, not a generic List. Is there a way to do this without iterating through the array to turn it into a generic List?
当然Foo.Split返回一个一维数组String，而不是一个泛型List。有没有办法在不遍历数组的情况下将其转换为泛型List？

If you don't want to use LINQ, you can do:
如果您不想使用 LINQ，可以执行以下操作：
Dim foo As String = "a,b,c,d,e"
Dim boo As New List(Of String)(foo.Split(","c))

You can use the List's constructor.
您可以使用 List 的构造函数。
String foo = "a,b,c,d,e";
List<String> boo = new List<String>(foo.Split(","));

Do you really need a List<T> or will IList<T> do? Because string[] already implements the latter... just another reason why it's worth programming to the interfaces where you can. (It could be that in this case you really can't, admittedly.)
你真的需要 List<T> 还是 IList<T> 会做？因为 string[] 已经实现了后者......这是值得对接口进行编程的另一个原因。（诚然，在这种情况下，您可能真的不能。）

The easiest method would probably be the AddRange method.
最简单的方法可能是 AddRange 方法。
Dim Foo as String = "a,b,c,d,e"
Dim Boo as List(of String)
Boo.AddRange(Foo.Split(","c))

Here is how I am doing it ... since the split is looking for an array of char I clip off the first value in my string.
这是我的做法......因为拆分正在寻找一个字符数组，所以我剪掉了字符串中的第一个值。
var values = labels.Split(" "[0]).ToList<string>();

To build on the answer, Ive found the following very helpful:
为了建立在答案的基础上，我发现以下内容非常有帮助：
Return New List(Of String)(IO.File.ReadAllLines(sFileName))

Dim Foo as String = "a,b,c,d,e"
Dim Boo as List(of String)
Boo = Split(Foo, ",").ToList
The advantage of doing it this way is that the split-string will accept multiple characters:
这样做的好处是拆分字符串将接受多个字符：
Dim Foo as String = "a<blah>b<blah>c<blah>d<blah>e"
Dim Boo as List(of String)
Boo = Split(Foo, "<blah>").ToList

If you use Linq, you can use the ToList() extension method
如果使用 Linq，则可以使用 ToList() 扩展方法
Dim strings As List<string> = string_variable.Split().ToList<string>();
