Alternative of php's explode/implode-functions in c#

String.Split() will explode, and String.Join() will implode.

The current answers are not fully correct, and here is why:

all works fine if you have a variable of type string[], but in PHP, you can also have KeyValue arrays, let's assume this one:

$params = array(
    'merchantnumber' => "123456789", 
    'amount' => "10095", 
    'currency' => "DKK"
);

and now call the implode method as echo implode("", $params); your output is

12345678910095DKK

and, let's do the same in C#:

var kv = new Dictionary<string, string>() {
             { "merchantnumber", "123456789" },
             { "amount", "10095" },
             { "currency", "DKK" }
         };

and use String.Join("", kv) we will get

[merchantnumber, 123456789][amount, 10095][currency, DKK]

not exactly the same, right?

what you need to use, and keep in mind that's what PHP does, is to use only the values of the collection, like:

String.Join("", kv.Values);

and then, yes, it will be the same as the PHP implode method

12345678910095DKK

There are two methods that correspond to PHP's explode and implode methods.

The PHP explode's equivalent is String.Split. The PHP implode's equivalent is String.Join.
