Strings.Join Strings.Join Strings.Join Method

Definition

Returns a string created by joining a number of substrings contained in an array.

Overloads

Join(Object[], String) Join(Object[], String) Join(Object[], String)

Returns a string created by joining a number of substrings contained in an array.

Join(String[], String) Join(String[], String) Join(String[], String)

Returns a string created by joining a number of substrings contained in an array.

Join(Object[], String) Join(Object[], String) Join(Object[], String)

Returns a string created by joining a number of substrings contained in an array.

public static string Join (object[] SourceArray, string Delimiter = " ");
static member Join : obj[] * string -> string
Public Function Join (SourceArray As Object(), Optional Delimiter As String = " ") As String

Parameters

SourceArray
Object[]

Required. One-dimensional array containing substrings to be joined.

Delimiter
String String String

Optional. Any string, used to separate the substrings in the returned string. If omitted, the space character (" ") is used. If Delimiter is a zero-length string ("") or Nothing, all items in the list are concatenated with no delimiters.

Returns

Returns a string created by joining a number of substrings contained in an array.

Exceptions

SourceArray is not one dimensional.

Examples

The following example demonstrates how to use the Join function to create a list from several strings.

Dim TestItem() As String = {"Pickle", "Pineapple", "Papaya"}
' Returns "Pickle, Pineapple, Papaya"
Dim TestShoppingList As String = Join(TestItem, ", ")

Remarks

There is a parity between the Join and Split functions. The Join function takes an array of strings and joins them using a delimiter string, to return a single string. The Split function takes a string and separates it at the delimiter, to return an array of strings. However, a key difference is that Join can concatenate strings with any delimiter string, Split can only separate strings using a single character delimiter.
