A simple string Concat   is what you need   string   test   new string 2    test 0     Hello    test 1     World     string result   string Concat test     If you also need to add a seperator  space  comma etc  then  string Join   should be used   string   test   new string 2    test 0     Red   test 1     Blue    string result   string Join      test     If you have to perform this on a string array with hundereds of elements than string Join   is better by performace point of view  Just give a     blank  argument as seperator  StringBuilder can also be used for sake of performance  but it will make code a bit longer

A slightly faster option than using the already mentioned use of the Join   method is the Concat   method  It doesn t require an empty delimiter parameter as Join   does  Example   string   test   new string 2   test 0     Hello    test 1     World     string result   String Concat test     hence it is likely faster

In the accepted answer  String Join isn t best practice per its usage  String Concat should have be used since OP included a trailing space in the first item   Hello    instead of using a null delimiter    However  since OP asked for the result  Hello World    String Join is still the appropriate method  but the trailing whitespace should be moved to the delimiter instead      string   test   new string 2       test 0     Hello       test 1     World     string   test      Hello    World        Alternative array creation syntax  string result   String Join      test
