拆分的字符串不分离 [英] split a string without separator

问题描述

我有值的字符串变量     abcdefghijklmnop。

I have a string variable with value "abcdefghijklmnop".

现在我想和说的3个字符（最后一个数组元素可以包含以下）从右端每个数组元素的字符串分割成字符串数组。

now I want to split the string into string array with say 3 characters(last array element may contain less) in each array element from the right end.

也就是说，
    一个
    BCD
    EFG
    HIJ
    荷航
    NOP

ie.,
"a"
"bcd"
"efg"
"hij"
"klm"
"nop"

什么是最简单，最容易做到这一点的方法？ （VB和C＃codeS的欢迎）

what is easiest and simplest way to do this?? (both vb and C# codes are welcomed)

推荐答案

下面是一个解决办法：

var input = "abcdefghijklmnop";
var result = new List<string>();
int incompleteGroupLength = input.Length % 3;
if (incompleteGroupLength > 0)
    result.Add(input.Substring(0, incompleteGroupLength));
for (int i = incompleteGroupLength; i < input.Length; i+=3)
{
    result.Add(input.Substring(i,3));
}

给出的预期输出：

Gives expected output of:

"a"
"bcd"
"efg"
"hij"
"klm"
"nop"
