Example

The following code example creates a new item collection named MySourceItemsWithMetadata from the item collection MySourceItems. The CreateItem task populates the new item collection with the items in the MySourceItems item. It then adds an additional metadata entry named MyMetadata with a value of Hello to each item in the new collection.

After the task is executed, the MySourceItemsWithMetadata item collection contains the items file1.resx and file2.resx, both with metadata entries for MyMetadata. The MySourceItems item collection is unchanged.

<Project xmlns="https://schemas.microsoft.com/developer/msbuild/2003">  
  
    <ItemGroup>  
        <MySourceItems Include="file1.resx;file2.resx" />  
    </ItemGroup>  
  
    <Target Name="NewItems">  
        <CreateItem  
            Include="@(MySourceItems)"  
            AdditionalMetadata="MyMetadata=Hello">  
           <Output  
               TaskParameter="Include"  
               ItemName="MySourceItemsWithMetadata"/>  
        </CreateItem>  
  
    </Target>  
  
</Project>  

The following table describes the value of the output item after task execution. Item metadata is shown in parenthesis after the item.
