How can i split the string only once using C#
提问by
Example : a - b - c must be split as a and b - c, instead of 3 substrings
示例：a - b - c 必须拆分为 a 和 b - c，而不是 3 个子字符串

Specify the maximum number of items that you want:
指定所需的最大项目数：
string[] splitted = text.Split(new string[]{" - "}, 2, StringSplitOptions.None);
回答by AgileJon
string s = "a - b - c";
string[] parts = s.Split(new char[] { '-' }, 2);
// note, you'll still need to trim off any whitespace

You could use indexOf() to find the first instance of the character you want to split with, then substring() to get the two aspects. For example...
您可以使用 indexOf() 找到要与之拆分的字符的第一个实例，然后使用 substring() 来获取两个方面。例如...
int pos = myString.IndexOf('-');
string first = myString.Substring(0, pos);
string second = myString.Substring(pos);
This is a rough example - you'll need to play with it if you don't want the separator character in there - but you should get the idea from this.
这是一个粗略的例子 - 如果你不想要分隔符，你需要使用它 - 但你应该从中得到想法。

string[] splitted = "a - b - c".Split(new char[]{' ', '-'}, 2, StringSplitOptions.RemoveEmptyEntries);
回答by SLaks
var str = "a-b-c";
int splitPos = str.IndexOf('-');
string[] split = { str.Remove(splitPos), str.Substring(splitPos + 1) };

I have joined late and many of above answers are matched with my following words:
我加入得很晚，上面的许多答案都与我的以下词相匹配：
string has its own
字符串有自己的
Split
分裂
You can use the same to find the solution of your problem, following is the example as per your issue:
您可以使用相同的方法来找到问题的解决方案，以下是针对您的问题的示例：
using System;
public class Program
{
public static void Main()
{
var PrimaryString = "a - b - c";
var strPrimary = PrimaryString.Split( new char[] { '-' }, 2 );
Console.WriteLine("First:{0}, Second:{1}",strPrimary[0],strPrimary[1]);
}
}
Output:
First:a , Second: b - c
