ExportServices

ExportServices is the sole component of SAIF.Services.Export and provides the library's entire export-formatting capability: turning any in-memory collection of objects into delimited (CSV-style) text without any knowledge of the specific business entity being exported. It is consumed directly by the Legal front-end web application to render query/business-result collections as downloadable text.*

Purpose

  • Owns the responsibility of formatting an arbitrary IEnumerable(Of T) collection as delimited text, using reflection (System.ComponentModel.TypeDescriptor) to discover the shape of T at runtime rather than requiring a statically declared mapping.
  • Provides the caller (a Legal web page or code-behind) with configurable delimiter and quoting behavior so the same method can serve differing export-format needs.*

Context

  • Namespace: SAIF.Services.Export
  • Assembly/package: SAIF.Services.Export (embedded .NET Framework 4.6.2 class library, referenced directly by Legal.vbproj)

Public members

Member Signature Purpose
GetCSV(Of T) Public Shared Function GetCSV(Of T)(ByVal inColl As IEnumerable(Of T), Optional ByVal Delimiter As String = ",", Optional ByVal UseQuotes As Boolean = True) As String Builds and returns a delimited text representation (header row plus one data row per item) of the supplied collection, discovering T's public properties via reflection; returns an empty string when the collection is empty, and silently omits null property values from a row rather than emitting an empty placeholder.*

Behavioral notes

  • The method is Shared (static) and stateless — it holds no instance state between calls.
  • Property discovery is performed twice: once against the first item (for the header row) and once per item during row construction, via TypeDescriptor.GetProperties/PropertyDescriptorCollection.*
  • Null property values are silently skipped during row construction rather than emitted as empty placeholders, which can misalign column counts across data rows when null values occur mid-row.*
  • No business-rule enforcement, validation, or database access occurs inside this type; formatting is purely mechanical and delimiter/quote-driven.

Constraints and usage notes

  • Callers must supply a homogeneous collection whose item type T exposes stable public properties, since the header row is derived only from the first item.*
  • The method offers no mechanism to preserve column alignment when null values occur mid-row; callers relying on fixed-width column output should be aware of this limitation.*
  • No exception handling is present in the method; reflection or ToString() failures on individual property values would propagate to the caller.**

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
