VB.NET Split Example – Code Sample Syntax
Abstract: – Illustrates using VB.NET Split Code Example.
*** 2. Split Syntax ***
Purpose:
Parses a string into a one-dimensional array of one or more
substrings. If the delimiter is not specified, space is used.
If the limit is not specified, all substrings are returned
Syntax:
Split(string[, delimiter][, limit])
Parameters |
Description |
string |
Required – string input that you want to parse into
a one-dimensional array using a delimiter and a limit
|
delimiter |
Optional – string delimiter that specifies
what separates the fields contained within the input string. If
no delimiter is given, space is used.
|
limit |
Optional – integer specifying maximum number of
fields to return to the one-dimensional array. If no limit is specified,
all substrings are returned.
|
Result Data Type |
Description |
string() |
Returns a one-dimensional string array that contains all
of the substrings that were returned from the input string.
|
*** 3. Split – Quick Example ***
|
Dim strField As String = “This”
Console.WriteLine(“[” + LTrim(strField) + Space(5) + “]”) ‘Returns [This ] with leading spaces removed

End Module
Prerequistes:
- Install Visual Basic (Express or Standard Edition)
- Install SQL Server Express
- Download Northwind and pubs Database
- Attach Northwind Database to Databases in Sql Express
- Attach pubs Database to Databases in Sql Express
Notes:
- Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
- You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.vb
Instructions:
- Use Visual Basic 2010 Express or Standard Edition
- Create new project;
- Click File/New Project
- Select Console Application Template
- Select Visual Basic for Language
- name of project could be VBNET_Syntax.
- Add New folder named “StringManipulation”
- Right-click project name in solution explorer;
- add new folder;
- name of folder could be: StringManipulation
- Add Class Named clsSplit to StringManipulation folder
- Right-click StringManipulation folder;
- add new item;
- Select class
- Class name could be clsSplit
- Click on Visual Basic in code in step 1 above to copy code into clsSplit.vb
- Click on Visual Basic in code in step 2 above to copy code into Module1.vb
- Click green arrow or press F5 to run program
