Convert array, `String`

The String.Join function in VB.NET combines many strings. With it we can convert a String array into a String.

There are a variety of ways you can convert a string array into a string. But the simplest way uses the String.Join function.

Example

Here we create a string array of 3 Strings. We call String.Join. The first argument is the separator character, which is placed between elements. The second argument is the array.

Result We can see the result of the program is joined together by a comma character.

Note No characters come before or after the String value. String.Join does not add the separator character after the final element.

Module Module1
    Sub Main()
        ' Input array.
        Dim array() As String = {"Dog", "Cat", "Python"}

        ' Convert to String data.
        Dim value As String = String.Join(",", array)

        ' Write to screen.
        Console.WriteLine("[{0}]", value)
    End Sub
End Module
[Dog,Cat,Python]

Separator note

If you need to have a separator character after the final element in the String, your best choice would probably be to use StringBuilder.

Info Call the Append method on every element in the array, followed by an Append to add the separator.

However The trailing separator is usually not required in my experience. It sometimes even causes problems.

We looked at the simplest way to convert a String array into a String in the VB.NET programming language. This approach is not the most flexible. But it is useful in certain situations.
