Defines a single item of the project as it is passed into a task.

System.Object
  System.MarshalByRefObject
    Microsoft.Build.Utilities.TaskItem

Namespace:  Microsoft.Build.Utilities
Assembly:  Microsoft.Build.Utilities.v4.0 (in Microsoft.Build.Utilities.v4.0.dll)
public sealed class TaskItem : MarshalByRefObject, 
	ITaskItem2, ITaskItem

The TaskItem type exposes the following members.

  Name Description
Public method TaskItem Initializes a new instance of the TaskItem class.
Public method TaskItem(ITaskItem) Initializes a new instance of the TaskItem class using the specified source ITaskItem.
Public method TaskItem(String) Initializes a new instance of the TaskItem class using the specified item-specification string.
Public method TaskItem(String, IDictionary) Initializes a new instance of the TaskItem class using the specified item-specification string and its metadata.

  Name Description
Public property ItemSpec Gets or sets the item specification.
Public property MetadataCount Gets the number of metadata set on the item.
Public property MetadataNames Gets the names of all the metadata on the item.

  Name Description
Public method CloneCustomMetadata Clones the collection of custom metadata for the item specification.
Public method CopyMetadataTo Copies the item-specification metadata to the specified destination task item.
Public method CreateObjRef Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetLifetimeService Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public method GetMetadata Retrieves the specified metadata on the item.
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method InitializeLifetimeService When overridden in a derived class, gives task items infinite lease time. (Overrides MarshalByRefObject.InitializeLifetimeService.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method MemberwiseClone(Boolean) Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Public method RemoveMetadata Removes the specified metadata on the item.
Public method SetMetadata Sets or modifies the value of the specified metadata on the item.
Public method ToString Gets the item specification. (Overrides Object.ToString.)

  Name Description
Public operator Static member Narrowing(TaskItem to String) Allows an explicit type cast from a TaskItem to a String, and returns the ItemSpec for that item.
Top
  Name Description
Explicit interface implemetation Private method ITaskItem2.CloneCustomMetadataEscaped ITaskItem2 implementation which returns a clone of the metadata on this object. Values returned are in their original escaped form.
Explicit interface implemetation Private property ITaskItem2.EvaluatedIncludeEscaped ITaskItem2 implementation which gets or sets the item include value. For disk-based items this would be the file path.
Explicit interface implemetation Private method ITaskItem2.GetMetadataValueEscaped ITaskItem2 implementation which allows the values of metadata on the item to be queried.
Explicit interface implemetation Private method ITaskItem2.SetMetadataValueLiteral ITaskItem2 implementation which allows a piece of custom metadata to be set on the item. Assumes that the value passed in is unescaped, and escapes the value as necessary in order to maintain its value.

TaskItem objects do not exactly correspond to item elements in project files. If they did, then tasks would have access to data that was not explicitly passed into the task through the project file. This is not a security issue, but rather an issue with project file clarity and transparency.

This class has to be sealed since the build engine instantiates its own copy of this type. If a third party were to extend this class, then the build engine will yield an undesired behavior.
