BuildItemGroup.GetEnumerator Method

Artikel
05/05/2015

Gets an enumerator that iterates through the BuildItemGroup.

MSBuild is now included in Visual Studio instead of the .NET Framework. You can use MSBuild 12.0 side-by-side with versions previously deployed with the .NET Framework.For more information, see What's New in MSBuild 12.0.

Namespace: Microsoft.Build.BuildEngine
Assembly: Microsoft.Build.Engine (in Microsoft.Build.Engine.dll)

Syntax

'Declaration
Public Function GetEnumerator As IEnumerator

public IEnumerator GetEnumerator()

public:
virtual IEnumerator^ GetEnumerator() sealed

abstract GetEnumerator : unit -> IEnumerator  
override GetEnumerator : unit -> IEnumerator

public final function GetEnumerator() : IEnumerator

Return Value

Type: System.Collections.IEnumerator
An IEnumerator for the entire BuildItemGroup.

Implements

IEnumerable.GetEnumerator()

Remarks

This method allows the caller to use the foreach statement of the C# language (for each in Visual Basic) to iterate through the individual BuildItem objects in the BuildItemGroup.

Examples

The following example creates a Project object and uses the BuildItem, BuildProperty BuildItemGroup, and BuildPropertyGroup classes to list all the items and properties in the project.

Module Module1
    'You need to add references to Microsoft.Build.BuildEngine and 
    'Microsoft.Build.Framework 
    Sub Main()
        'Set this to point to the location where the 2.0 clr/tools are installed
        Engine.GlobalEngine.BinPath = "C:\windows\microsoft.net\framework\v2.0.xxxxx" 

        'Create a new empty project 
        Dim project As New Project()

        'Load a project
        project.Load("c:\temp\validate.proj")

        'Output a header
        Console.WriteLine("Project Properties")
        Console.WriteLine("----------------------------------")

        'Iterate through the various property groups and subsequently 
        'through the various properties 
        For Each propertyGroup As BuildPropertyGroup In project.PropertyGroups
            For Each prop As BuildProperty In propertyGroup
                Console.WriteLine("{0}:{1}", prop.Name, prop.Value)
            Next 
        Next

        Console.WriteLine()
        Console.WriteLine("Project Items")
        Console.WriteLine("----------------------------------")

        'Iterate through the various itemgroups 
        'and subsequently through the items 
        For Each itemGroup As BuildItemGroup In project.ItemGroups
            For Each item As BuildItem In itemGroup
                Console.WriteLine("{0}:{1}", item.Name, item.Include)
            Next 
        Next 
    End Sub
