我如何将我的字符串分成相等的一半并将其存储在变量中 [英] How do i split my string in equal half and store that in variable

问题描述

string value =monobala;



我需要将mono和bala存储在不同的变量或数组中



我尝试过：



value.split（value.length> 2）

我不确切知道该做什么

string value="monobala";

I need to store mono and bala in different variable or in array

What I have tried:

value.split(value.length>2)
I dont know exactly what to do

推荐答案

对于偶数编号的字符串，它很容易：

For even numbered strings its easy:

var MyString = "blabla";
var first = MyString.Substring(0, (int)(MyString.Length / 2));
var last = MyString.Substring((int)(MyString.Length / 2), (int)(MyString.Length / 2));

对于奇数字符串，你需要选择如何拆分它们。

For odd number strings, you need to make a choise on how to split them.

我是真的想知道你可能在哪个班级，或者现实世界中的什么样的编程任务，可能需要根据一半的想法将字符串分成两部分。



但是，这很容易做到。这是你可以做到的一种方法：

I'm really wondering what kind of class you may be in, or what kind of programming task in the real world, could possibly require splitting a string into two parts based on the idea of "half."

However, it's easy to do. Here's one way you could do it:

string bar = "|";
string[] splitStr = new string[] {bar};
string str = "12345678";

string[] byHalf = str.Insert(str.Length / 2, bar).Split(splitStr,StringSplitOptions.RemoveEmptyEntries);

当然，如果你要拆分的字符串有你用来拆分的字符，这个方法很容易混淆。



这是一个使用'StringBuilder供你学习的例子：

Of course, this method is easily confused if the string you are splitting has the character you use to split it with.

Here's an example using 'StringBuilder for you to study:

string str = "12345678";
StringBuilder sb = new StringBuilder(str);
int half1 = sb.Length/2;
int half2 = sb.Length - half1;
char[] halfOne = new char[half1];
char[] halfTwo = new char[half2];
sb.CopyTo(0, halfOne, 0, half1);
sb.CopyTo(half1, halfTwo, 0, half2);
string[] results = new string[]
{
   new string(halfOne), new string(halfTwo)
};
sb.Clear();

了解每一步中发生的事情，当你处于编程场景中时，你会学到一些有用的东西。处理重字符串使用：）

Understand what's going on in each step of this, and you'll learn something that will be useful in the future when you are in a programming scenario where you have to deal with "heavy" string use :)

建立在 @Kenneth Haugland 的奇数字符串的答案（为你懒惰的人 - 和我一样）。

Building on @Kenneth Haugland's answer for odd strings (for you lazy folk - like me).

var value = "monobala";
var firstHalfLength = (int)(value.Length / 2);
var secondHalfLength = value.Length - firstHalfLength;
var splitPhone = new[] 
    {
        value.Substring(0, firstHalfLength),
        value.Substring(firstHalfLength, secondHalfLength)
    };
