Question

I have a string array variable.

private string[] _documents;

Values to it are assigned like this.

string[] _documents = { "doc1", "doc2", "doc3" };

And there’s a method which adds a string to that array and returns it.

public string GetMail()
{
    return originalMessage + " " + _documents[0];
}

Defining _documents[0] returns only the first element of the array.

How can I return all the elements in the array? (Kinda like what implode function does in PHP)

I am not familiar with PHP, but you can concatenate all elements of a string array with string.Join:

return string.Join(" ", docs);

The first parameter is the separator; you can pass an empty string if you do not need separators.
