GetItemProvenance(ProjectItem)
- Source:
- Project.cs
Overload of GetItemProvenance(String).
public:
System::Collections::Generic::List<Microsoft::Build::Evaluation::ProvenanceResult ^> ^ GetItemProvenance(Microsoft::Build::Evaluation::ProjectItem ^ item);public System.Collections.Generic.List<Microsoft.Build.Evaluation.ProvenanceResult> GetItemProvenance (Microsoft.Build.Evaluation.ProjectItem item);member this.GetItemProvenance : Microsoft.Build.Evaluation.ProjectItem -> System.Collections.Generic.List<Microsoft.Build.Evaluation.ProvenanceResult>Public Function GetItemProvenance (item As ProjectItem) As List(Of ProvenanceResult)Parameters
- item
- ProjectItem
The ProjectItem object that indicates: the itemspec to match and the item type to constrain the search in.
The search is also constrained on item elements appearing before the item element that produced this item.
The element that produced this item is included in the results.
Returns
Applies to
GetItemProvenance(String)
- Source:
- Project.cs
Finds all the item elements in the logical project with itemspecs that match the given string:
- elements that would include (or exclude) the string
- elements that would update the string (not yet implemented)
- elements that would remove the string (not yet implemented).
public:
System::Collections::Generic::List<Microsoft::Build::Evaluation::ProvenanceResult ^> ^ GetItemProvenance(System::String ^ itemToMatch);public System.Collections.Generic.List<Microsoft.Build.Evaluation.ProvenanceResult> GetItemProvenance (string itemToMatch);member this.GetItemProvenance : string -> System.Collections.Generic.List<Microsoft.Build.Evaluation.ProvenanceResult>Public Function GetItemProvenance (itemToMatch As String) As List(Of ProvenanceResult)Parameters
- itemToMatch
- String
The string to perform matching against.
Returns
A list of ProvenanceResult, sorted in project evaluation order.
Examples
The following snippet shows what <code data-dev-comment-type="c">GetItemProvenance("a.cs")</code> returns for various item elements.
<A Include="a.cs;*.cs"></A> // Occurrences:2; Operation: Include; Provenance: StringLiteral | Glob
<B Include="*.cs" Exclude="a.cs"></B> // Occurrences: 1; Operation: Exclude; Provenance: StringLiteral
<C Include="b.cs"></C> // NA
<D Include="@(A)"></D> // Occurrences: 2; Operation: Include; Provenance: Inconclusive (it is an indirect occurrence from a referenced item)
<E Include="$(P)"></E> // Occurrences: 4; Operation: Include; Provenance: FromLiteral (direct reference in $P) | Glob (direct reference in $P) | Inconclusive (it is an indirect occurrence from referenced properties and items)
<PropertyGroup><P>a.cs;*.cs;@(A)</P></PropertyGroup>
Remarks
This method and its overloads are useful for clients that need to inspect all the item elements that might refer to a specific item instance. For example, Visual Studio uses it to inspect projects with globs. Upon a file system or IDE file artifact change, VS calls this method to find all the items that might refer to the detected file change (e.g. 'which item elements refer to "Program.cs"?'). It uses such information to know which elements it should edit to reflect the user or file system changes.
Literal string matching tries to first match the strings. If the check fails, it then tries to match the strings as if they represented files: it normalizes both strings as files relative to the current project directory
GetItemProvenance suffers from some sources of inaccuracy: - it is performed after evaluation, thus is insensitive to item data flow when item references are present (it sees items as they are at the end of evaluation)
This API and its return types are prone to change.
