ProjectItem.SetMetadataValue Method

Definition

Namespace:

Microsoft.Build.Evaluation

Assembly:

Microsoft.Build.dll

Package:

Microsoft.Build v17.11.4

Overloads

SetMetadataValue(String, String)

Adds metadata with the specified name and value to the item. Updates an existing metadata if one already exists with the same name on the item directly, as opposed to inherited from an item definition. Updates the evaluated project, but does not affect anything else in the project until reevaluation. For example, if a piece of metadata named "m" is added on item of type "i", it does not affect "j" which is evaluated from "@(j->'%(m)')" until reevaluation. Also if the unevaluated value of "m" is set to something that is modified by evaluation, such as "$(p)", the evaluated value will be set to literally "$(p)" until reevaluation. This is a convenience that it is understood does not necessarily leave the project in a perfectly self consistent state without a reevaluation. Returns the new or existing metadatum.

SetMetadataValue(String, String, Boolean)

Overload of SetMetadataValue(String, String). Adds the option of not splitting the item element and thus affecting all sibling items. Sibling items are defined as all ProjectItem instances that were created from the same item element. This is a convenience that it is understood does not necessarily leave the project in a perfectly self consistent state without a reevaluation

Parameters

name

Public Function SetMetadataValue (name As String, unevaluatedValue As String, propagateMetadataToSiblingItems As Boolean) As ProjectMetadata

Parameters

name

String

Metadata name

unevaluatedValue

String

Metadata value

propagateMetadataToSiblingItems

Returns

ProjectMetadata

Returns the new or existing metadatum.
