VB.NET Convert String Array to String

Converts a String array into a single String. Invoke the string.Join function with correct arguments.
Convert string array, string. String.Join combines many strings. With it we can convert a String array into a String. There are a variety of ways you can accomplish this task. But the simplest way uses the String.Join function.Array
Example. Here we create a string array of 3 String literals on the managed heap. We call String.Join. The first argument is the separator character, which is placed between elements. The second argument is the array reference itself.

Result: We can see the result of the program is the String "Dot.Net.Perls".

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

VB.NET program that converts array to string Module Module1 Sub Main() ' Input array. Dim array() As String = {"Dot", "Net", "Perls"} ' Convert to String data. Dim value As String = String.Join(".", array) ' Write to screen. Console.WriteLine("[{0}]", value) End Sub End Module Output [Dot.Net.Perls]
Separators. If you need to have a separator character after the final element in the String, your best choice would probably be to use StringBuilder. 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.

Summary. 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.

Tip: If more flexibility is required, an imperative approach—looping and calling StringBuilder's Append function—could be used.
