Shared member

Learn Shared member in Visual Basic .NET through a focused explanation, a dedicated construct-specific example, an engineering boundary, and a mastery check.

10 min read • Intermediate

Shared member is an atomic Visual Basic .NET topic inside OOP. This lesson focuses on how the Shared member construct is written, what it changes, and when it is the right tool.

Trace the example line by line. Identify the exact syntax for Shared member, the input state before it runs, and the resulting value, control flow, database state, hardware behavior, or runtime effect afterward. Neighboring lessons use different constructs rather than renamed copies of this one.

Topic-specific example

vbnet-04-10-shared-member.vb
vbnet Try It Live 
Class Ids
    Public Shared NextId As Integer=1
End Class
Ids.NextId+=1
Console.WriteLine(Ids.NextId)
Edge case / engineering note

For Shared member, test the boundary that belongs to this exact feature rather than a generic failure case. Check invalid or empty input, NULL/unknown state, numeric limits, transaction or exception behavior, synthesis/runtime constraints, ownership/permission rules, or backtracking/control-flow effects where they apply.
