如何合并回拆分的字符串？

Question

I like how I can do string [] stringArray = sz.split('.');

but is there a way to merge them back together? (stringArray.Merge(".");)

Answer 1

string mergedString = String.Join(" ", stringArray);

Answer 2

字符串连接

Answer 3

String.Join()

Answer 4

字符串合并= String.Concat（stringArray）;

Answer 5

Suppose there is a phone number like:

string str = "^^^^^546^64767";
string resultString = String.Join("-", str.Split(new string[] { "^" }, StringSplitOptions.RemoveEmptyEntries));

So you can join like this.
