您可以使用 MultiBinding 结合 StringFormat 属性。用法类似于以下内容：

You can use a MultiBinding combined with the StringFormat property. Usage would resemble the following:

<TextBlock>
    <TextBlock.Text>    
        <MultiBinding StringFormat="{}{0} + {1}">
            <Binding Path="Name" />
            <Binding Path="ID" />
        </MultiBinding>
    </TextBlock.Text>
</TextBlock>

给定一个名称为 Foo 的值您在TextBlock中输出的ID为 1 的值将为 Foo + 1 。

Given a value of Name of Foo and a value for ID of 1 you output in the TextBlock would be Foo + 1.

注意： 仅在.NET 3.5 SP1和3.0 SP2或更高版本中支持。

Note: that this is only supported in .NET 3.5 SP1 and 3.0 SP2 or later.
