visual-studio 使用 T4 获取项目或相关目录

Get Project or Relative Directory with T4

提问by Blake Taylor

How can I get a reference to the directory of the visual studio project or solution or the directory of the t4 template from within a t4 template?

如何从 t4 模板中获取对 Visual Studio 项目或解决方案目录或 t4 模板目录的引用？

I have a template that concatenates a number of files together which are located relative to the template. I need to get a reference to there absolute location through a relative means. Hard coding an absolute path is not acceptable because the visual studio project will not always be in the same location and this would break the code generation. Reading the current working directory from the environment doesn't work either because that returns the location of where the T4 engine lives not the template. I'm just getting in to t4 so any help would be appreciated.

我有一个模板，它将多个文件连接在一起，这些文件相对于模板定位。我需要通过相对方式获得对绝对位置的引用。硬编码绝对路径是不可接受的，因为 Visual Studio 项目并不总是位于同一位置，这会破坏代码生成。从环境中读取当前工作目录也不起作用，因为它返回的是 T4 引擎所在的位置而不是模板。我刚刚进入 t4，所以任何帮助将不胜感激。

See The Host Specific Parametersection HERE.

请参阅此处的主机特定参数部分。

This snippet shows how to get the full path of src relative to the template.

此代码段显示了如何获取 src 相对于模板的完整路径。

<#@ template hostspecific="true" #>
// The location of the src folder relative to the t4 template:
// <#= Host.ResolvePath("src") #>

You can grab the path like this aswell

你也可以这样抓取路径

<#@ template hostspecific="true" #>
<#= Path.GetDirectoryName(this.Host.TemplateFile) #>
