How to Convert Array to string [duplicate]

Question

I want to convert Array into string as

string[] parts={"1","2","3","4"};

and output as

string str="%1%2%3%4%";

string.Join("%", parts) then add in the start and end %. — DavidG

Linq: parts.Aggregate("%", (current, next) => current + next + "%") — Klaudiusz bryjamus

@Klaudiuszbryjamus While clever this suffers from the concatenating strings in a loop problem. — juharr

@juharr But this is simple linq query not in loop so you can use linq — Klaudiusz bryjamus

Use string.Join:

var str = string.Join("%", parts);

And add in the surrounding % marks:

str = string.format("%{0}%", str);

Using C#-6 string interpolation:

var str = $"%{string.Join("%", parts)}%";

Probably worth mentioning this will only work in C#6.

string.Join will concatenate the strings in the array with a delimiter. Then you just have to add the "%" to the beginning and end.

string str = "%" + string.Join("%", parts) + "%";

    StringBuilder builder = new StringBuilder();    
    foreach(string tmp in parts)
    {
       builder.append("%");
       builder.append(tmp);
    }
    builder.append("%");
    string result = builder.ToString();
