Name

Join Function

Class

Microsoft.VisualBasic.Strings

Syntax

result = Join(sourcearray, [delimiter])
sourcearray (required; String or Object array)

Array whose elements are to be concatenated

delimiter (optional; String)

Character used to delimit the individual values in the string

Return Value

String

Description

Concatenates an array of values into a delimited string using a specified delimiter

Rules at a Glance

  • If no delimiter is specified, the space character is used as a delimiter.

  • If you want to concatenate numeric or other nonstring values in sourcearray, use an Object array. If, for example, you specify a numeric data type for sourcearray, the function will generate a compiler error.

Programming Tips and Gotchas

The Join function is ideal for quickly and efficiently writing out a comma-delimited text file from an array of values.
