string[]is an array (vector) of strings
stringis just a string (a list/array of characters)
string[]是字符串数组（向量）
string只是字符串（字符列表/数组）
Depending on how you want to convert this, the canonical answer could be:
根据您想如何转换它，规范的答案可能是：
string[] -> string
字符串[] -> 字符串
return String.Join(" ", myStringArray);
string -> string[]
字符串 -> 字符串[]
return new []{ myString };

stringis a string, and string[]is an array of strings
string是一个字符串，并且string[]是一个字符串数组
回答by Simeon Visser
A stringis one string, a string[]is a string array. It means it's a variable with multiple strings in it.
Astring是一个字符串，astring[]是一个字符串数组。这意味着它是一个包含多个字符串的变量。
Although you can convert a stringto a string[](create a string array with one element in it), it's probably a sign that you're trying to do something which you shouldn't do.
尽管您可以将 a 转换string为 a string[]（创建一个包含一个元素的字符串数组），但这可能表明您正在尝试做一些不应该做的事情。

zerkms told you the difference. If you like you can "convert" a string to an array of strings with length of 1.
zerkms 告诉你区别。如果您愿意，可以将字符串“转换”为长度为 1 的字符串数组。
If you want to send the string as a argument for example you can do like this:
例如，如果您想将字符串作为参数发送，您可以这样做：
var myString = "Test";
MethodThatRequiresStringArrayAsParameter( new[]{myString} );
I honestly can't see any other reason of doing the conversion than to satisty a method argument, but if it's another reason you will have to provide some information as to what you are trying to accomplish since there is probably a better solution.
老实说，除了满足方法参数之外，我看不出任何其他原因进行转换，但是如果这是另一个原因，您将不得不提供一些有关您要完成的任务的信息，因为可能有更好的解决方案。

An array is a fixed collection of same-type data that are stored contiguously and that are accessible by an index (zero based).
数组是相同类型数据的固定集合，这些数据连续存储并可通过索引（从零开始）访问。
A string is a sequence of characters.
字符串是一个字符序列。
Hence a String[]is a collection of Strings.
因此 aString[]是 的集合Strings。
For example:
例如：
String foo = "Foo"; // one instance of String
String[] foos = new String[] { "Foo1", "Foo2", "Foo3" };
String firstFoo = foos[0]; // "Foo1"
Edit: So obviously there's no direct way to convert a single Stringto an String[]or vice-versa. Though you can use String.Splitto get a String[]from a Stringby using a separator(for example comma).
编辑：很明显，没有直接的方法可以将单个转换为一个String，String[]反之亦然。尽管您可以使用分隔符（例如逗号）从 a 中String.Split获取 a 。String[]String
To "convert" a String[]to a String(the opposite) you can use String.Join. You need to specify how you want to join those strings(f.e. with comma).
要将 a 转换String[]为 a String（相反），您可以使用String.Join. 您需要指定如何加入这些字符串（fe 用逗号）。
Here's an example:
下面是一个例子：
var foos = "Foo1,Foo2,Foo3";
var fooArray = foos.Split(','); // now you have an array of 3 strings
foos = String.Join(",", fooArray); // now you have the same as in the first line

You can create a string[](string array) that contains your stringlike :
您可以创建一个string[]包含您string喜欢的（字符串数组）：
string someString = "something";
string[] stringArray = new string[]{ someString };
The variable stringArraywill now have a length of 1 and contain someString.
该变量stringArray现在的长度为 1 并包含someString.

In case you are just a beginner and want to split a string into an array of letters but didn't know the right terminology for that is a char[];
如果你只是一个初学者，想把一个字符串拆分成一个字母数组，但不知道正确的术语是 char[];
String myString = "My String";
char[] characters = myString.ToCharArray();
If this is not what you were looking for, sorry for wasting your time :P
如果这不是您要找的东西，很抱歉浪费您的时间：P

Casting can also help converting string to string[]. In this case, casting the string with ToArray() is demonstrated:
转换还可以帮助将字符串转换为字符串 []。在这种情况下，演示了使用 ToArray() 转换字符串：
String myString = "My String";
String[] myString.Cast<char>().Cast<string>().ToArray();

If you want to convert a string like "Mohammad"to String[]that contains all characters as String, this may help you:
如果你想将字符串转换一样"Mohammad"，以String[]包含所有字符String，这可以帮助你：
"Mohammad".ToCharArray().Select(c => c.ToString()).ToArray()
