将字符串传递给数组 [英] Passing string to an array

问题描述

我有一个名为str ="4,5,6"的字符串，
我想将这些值分配给数组
即数组中的第一个元素为4，
第二个是5，等等，
在这里我给出了3个值，但实际上我不知道它在字符串中有多少个值，
是否可以将该字符串分配给数组，
如果您知道可以帮助我，
在我需要的应用程序中.

I have a string called str="4,5,6",
i want to assign those values to an array
i.e in the array the first element is 4,
second is 5, etc,,
here i gave 3 values but actually i dont know how many values it have in string,
is it possible to assign that string to an array,
if u know help me,
in my app that is need.

推荐答案

string str = "4,5,6";
string[] strings = str.Split(',');

或者如果您希望将其作为int []:

or if you want it as int[]:

string str = "4,5,6";
string[] strings = str.Split(',');
int[] ints = new int[strings.Length];
for(int i = 0; i < strings.Length; i++)
{
  Int32.TryParse(strings[i], out ints[i]);
}

有相应的方法:

There''s method for that :

string[] s = "4,5,6".Split('','');

到int数组:

to int array :

int[] ints = s.Select(x => int.Parse(x)).ToArray();

欢呼

Cheers

Dim str as string="4,5,6"

Dim arr() As String = str.ToString.Split(",")

现在，使用for循环，您可以将此数据添加到任何数据表，数据集中或根据您的要求.

例如将此数据添加到列表框

Now, using for loop you can add this data in any datatable, dataset or as per your requirement.

For Eg. to add this data in Listbox

For i As Integer = 0 To arr.Length - 1
            ListBox1.Items.Add(arr(i).ToString)
        Next
