use foreach loop and fetch and merge each string item from array.

Really bad idea. Even if you do it in a loop... As string is immutable, it's really bad for performance.

Amazingly, this answer is the only acceptable one so far. Other did not realize that strings are immutable, so concatenation is bad for performance. My 5.

C#

String[] a = {"1","2","3"};
String result = "";
int i = 0;
while(i< a.Length)
{
result = result + a[i];
i++;
}

Really, really bad solution. It will work, but you are missing that strings are immutable, so loop with concatenation will be bad for performance. The only valid solution so far it the Solution 5.

Solution 1

Hi,
you can try this:

C#

string[] _str = new string[]{"a","b","c"};
           string val = string.Concat(_str);
