什么是C#方法/语法转换数组一个简单的字符串? [英] What's the C# method/syntax for converting an array to a simple string?
问题描述
我正在寻找的是JavaScript的基本相当于阵列::连接()
,让你传递一个分隔符,并使用在所有的返回字符串下标。我可以使用的StringBuilder
或诸如此类的东西肯定是写我自己的功能,但也的必须的东西内置到.NET基础类库。
What I'm looking for is a basic equivalent of JavaScript's Array::join()
whereby you pass in a separator character and uses that in its return string of all the subscripts. I could certainly write my own function using a StringBuilder
or whatnot, but there must be something built into the .NET BCL.
编辑:的的什么阵的,不一定字符串
或字符
。我想preFER的方法来简单地调用的ToString()
每个标对象
上。 的string.join()
是伟大的,除非你把它传递一个字符串数组。
Array of anything, not necessarily string
or char
. I'd prefer the method to simply call ToString()
on each subscript object
. String.Join()
is great except that you pass it an array of strings.
推荐答案
如果数组包含字符串,你可以使用的 的string.join()
。如果阵列中不包含字符串,你需要的东西多一点复杂的,所以你可以处理投或转换过程中的每个它所包含的项目。
If the array contains strings, you can just use String.Join()
. If the array does not contain strings, you'll need something a little more complicated so you can handle the cast or conversion process for each item it contains.
更新:使用@ JaredPar的code为基础,一个更通用的例子:
Update: Using @JaredPar's code as the basis for a more generic example:
char sep = GetSeparatorChar();
object[] toJoin = GetToJoin();
string joined = toJoin.Aggregate((x,y) => x.ToString()+sep.ToString()+y.ToString());
显然,你可以做你想要的X和Y任何在这个例子中得到的字符串看你怎么想。
Obviously you could do anything you wanted to x and y in that example to get the string to look how you wanted.
