The results of the preceding project le are identical to the example shown in Properties07.proj, but the syntax is much clearer. If you are using MCBuild 3.5, then using the PropertyGroup directly inside the target is the preferred approach. This syntax is not supported by MSBuild 2.0 so be sure not to use it in such les. Now that we have thoroughly covered properties, we ll move on to discuss items in detail.

When software is being built, les and directories are used heavily. Because of the usage and importance of les and directories, MSBuild has a speci c construct to support these. This construct is items. In the previous section we covered properties. As stated previously, in programming terms properties can be considered a regular scalar variable. This is because a property has a unique name and a single value. An item can be thought of as an array. This is because an item has a single name but can have multiple values. Properties use the PropertyGroup to declare properties; similarly, items use an ItemGroup element. Take a look at the following very simple example from Items01.proj.

As stated previously, statically declared items will be inside an ItemGroup element. The value for the Include attribute determines what values get assigned to the item. Of the few types of values that can be assigned to the Include attribute, we ll start with the simplest. The simplest value for the Include is a text value. In the previous sample one item, SrcFiles, is declared. The SrcFiles item is set to include one le, which is located at src\one.txt. To get the value of an item you use the @(ItemName) syntax. In the Print target this is used on the SrcFiles item. The result of the Print target is shown in Figure 2-7.

FIGURE 2-7 Print target result for Items01.proj
From the result shown in Figure 2-7, you can see that the le was assigned to the SrcFiles item as expected. From this example an item seems to behave exactly as a property; this is because we assigned only a single value to the item. The behavior changes when there are more values assigned to the item. The following example is a modi ed version of the previous example. This modi ed version is contained in the Items02.proj le.
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <ItemGroup> <SrcFiles Include="src\one.txt" /> <SrcFiles Include="src\two.txt" /> </ItemGroup> <Target Name="Print"> <Message Text="SrcFiles: @(SrcFiles)" /> </Target> </Project>
In this version, the SrcFiles item type is declared twice. When more than one item declaration is encountered the values are appended to each other, instead of overwritten like properties. Alternatively you could have declared the SrcFiles item on a single line by placing both values inside the Include attribute, separated by a semi-colon. So the previous sample would be equivalent to the following one. With respect to item declarations, ordering is signi cant and preserved.
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <ItemGroup> <SrcFiles Include="src\one.txt;src\two.txt" /> </ItemGroup> <Target Name="Print"> <Message Text="SrcFiles: @(SrcFiles)" /> </Target> </Project>

Overview
If you execute the Print target on this le the result will be what is shown in Figure 2-8.

In this version, we have supplied two values into the SrcFiles item. If you look at the documentation for the Message task you will notice that the Text property is a string. Fundamentally there are two types of values in MSBuild: single-valued values and multi-valued values. Another name for these is scalar values and vector values respectively. Properties are scalar values, and items are vector values. What happens when we have a vector value where we need to pass to a task that is accepting only scalar values MSBuild must rst atten the item before sending it to the task. The value that is passed to the Text property on the Message can be only a single-valued parameter, not a multi-valued one. For the SrcFiles item to be attened before it is sent into the task, the @(ItemName) operator takes care of this for us. When using the @(ItemName) if there is only one value inside the item, that value is used. If there is more than one value contained by the item, then all values are combined, separated by a semicolon. This is the most basic example of an item transformation. We ll discuss this in more detail later in this chapter. For now, let s move on to see how items are more commonly used.
