在第一个空格处划分一个字符串

For a chat-bot, if someone says "!say " it will recite what you say after the space. Simple.

对于聊天机器人，如果有人说“！说”，它会在空间后背诵你所说的内容。简单。

Example input:

示例输入：

!say this is a test

Desired output:

期望的输出：

this is a test

The string can be represented as s for sake of argument. s.Split(' ') yields an array.

为了论证，字符串可以表示为s。 s.Split（''）产生一个数组。

s.Split(' ')[1] is just the first word after the space, any ideas on completely dividing and getting all words after the first space?

s.Split（''）[1]只是空间之后的第一个单词，是否有关于在第一个空格之后完全划分和获取所有单词的任何想法？

I've tried something along the lines of this:

我尝试过这样的事情：

s.Split(' ');
for (int i = 0; i > s.Length; i++)
{
    if (s[i] == "!say")
    {
        s[i] = "";
    }
}

The input being:

输入是：

!say this is a test

The output:

输出：

!say

Which is obviously not what I wanted :p

这显然不是我想要的：p

(I know there are several answers to this question, but none written in C# from where I searched.)

（我知道这个问题有几个答案，但没有一个用C＃从我搜索的地方写的。）

4 个解决方案

#1

Use the overload of s.Split that has a "maximum" parameter.

使用具有“最大”参数的s.Split的重载。

Looks like:

好像：

var s = "!say this is a test";
var commands = s.Split (' ', 2);

var command = commands[0];  // !say
var text = commands[1];     // this is a test

#2

You can use string.Substring method for that:

您可以使用string.Substring方法：

s.Substring(s.IndexOf(' '))

#3

var value = "say this is a test";
return value.Substring(value.IndexOf(' ') + 1);

#4

This code is working for me. I added the new [] and it works

这段代码对我有用。我添加了新的[]并且它有效

var s = "!say this is a test";
var commands = s.Split (new [] {' '}, 2);

var command = commands[0];  // !say
var text = commands[1];     // this is a test
