使用 T4 生成 WMAppManifest.xml

本文关键字：xml WMAppManifest 生成 T4 使用 | 更新日期: 2023-09-27 18:32:26

我有一个只返回AssemblyInfo中的值的类.cs（此代码适用于Windows Phone）：

using System.Runtime.InteropServices;
using System.Reflection;
namespace Tiletoons
{
    class AppInfo
    {
        public static readonly string Id = string.Empty;
        public static readonly string Product = string.Empty;
        public static readonly string Company = string.Empty;
        public static readonly string Version = string.Empty;
        static AppInfo()
        {
            Assembly assembly = Assembly.GetExecutingAssembly();
            foreach (object attribute in assembly.GetCustomAttributes(false)) {
                if (attribute.GetType() == typeof(GuidAttribute)) {
                    Id = (attribute as GuidAttribute).Value;
                } else if (attribute.GetType() == typeof(AssemblyProductAttribute)) {
                    Product = (attribute as AssemblyProductAttribute).Product;
                } else if (attribute.GetType() == typeof(AssemblyCompanyAttribute)) {
                    Company = (attribute as AssemblyCompanyAttribute).Company;
                } 
            }
            Version = assembly.FullName.Split('=')[1].Split(',')[0];
        }
    }
}

。我想使用它通过 T4 转换自动生成我的 WMApp.xml清单;这是我的ttinclude文件：

<#@ assembly name="System.Core" #>
<#@ assembly name="EnvDTE" #>
<#@ import namespace="EnvDTE" #>
<#@ import namespace="System" #>
<# 
IServiceProvider hostServiceProvider = Host as IServiceProvider;
EnvDTE.DTE dte = hostServiceProvider.GetService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
EnvDTE.ProjectItem containingProjectItem = dte.Solution.FindProjectItem(Host.TemplateFile);
Project project = containingProjectItem.ContainingProject;
var projectName = project.FullName;
ProjectItem deploymentConfiguration = GetProjectItem(project, "AppInfo.cs");
if (deploymentConfiguration == null) {
    throw new Exception("Unable to resolve AppInfo.cs");
}
var codeModel = deploymentConfiguration.FileCodeModel;
string id = null;
string product = null;
string company = null;
string version = null;
foreach (CodeElement codeElement in codeModel.CodeElements) {
    if (codeElement.Name == "AppInfo") {
        CodeClass codeClass = codeElement as CodeClass;
        foreach (CodeElement memberElement in codeClass.Members) {
            CodeVariable variable = memberElement as CodeVariable;
            switch (memberElement.Name) {
                case "Id":
                    id = variable.InitExpression as string;
                    break;
                case "Product":
                    product = variable.InitExpression as string;
                    break;
                case "Company":
                    company = variable.InitExpression as string;
                    break;
                case "Version":
                    version = variable.InitExpression as string;
                    break;
             }
        }
    }
} 
#>
<#+ EnvDTE.ProjectItem GetProjectItem(Project project, string fileName)
{
    foreach (ProjectItem projectItem in project.ProjectItems) {
        if (projectItem.Name.EndsWith(fileName)) {
            return projectItem;
        }
        var item = GetProjectItem(projectItem, fileName);
        if (item != null) {
            return item;
        }
    }
    return null;
}
EnvDTE.ProjectItem GetProjectItem(EnvDTE.ProjectItem projectItem, string fileName)
{
    if (projectItem.ProjectItems != null && projectItem.ProjectItems.Count > 0) {
        foreach (ProjectItem item in projectItem.ProjectItems) {
            if (item.Name.EndsWith(fileName)) {
                return item;
            }
        }
    }
    return null;
} 
#>

。最后这是我的清单模板：

<#@ template debug="false" hostspecific="true" language="C#" #>
<#@ output extension=".xml" #>
<#@ include file="AppInfo.ttinclude" #>
<?xml version="1.0" encoding="utf-8"?>
<Deployment xmlns="http://schemas.microsoft.com/windowsphone/2009/deployment" AppPlatformVersion="7.0">
    <App xmlns="" ProductID="<#= id #>" Title="<#= product #>" RuntimeType="XNA" Version="<#= version #>" Genre="apps.games" Author="Gonzo" Description="<#= description #>" Publisher="<#= company #>">
    <IconPath IsRelative="true" IsResource="false">
    ...
  </App>
</Deployment>

是否可以使用像我这样的类 （AppInfo） 填充清单模板？我不想重复AssemblyInfo.cs中已经定义的常量，即这个想法是从那里查看发布我的WP应用程序所需的所有信息。

任何想法都会受到热烈欢迎：-）

使用 T4 生成 WMAppManifest.xml

好吧，我的应用程序有两种不同的部署配置（精简版或专业版），对于每种配置，我都需要特定的 Guid、标题名称、版本等。我能够通过修改这样的 WMAppManifest.tt 来解决我的问题：

<#@ template debug="false" hostspecific="true" language="C#" #>
<#@ output extension=".xml" #>
<#@ assembly name="$(TargetPath)" #>
<?xml version="1.0" encoding="utf-8"?>
<Deployment xmlns="http://schemas.microsoft.com/windowsphone/2009/deployment" AppPlatformVersion="7.0">
    <App xmlns="" ProductID="<#= AppInfo.Id #>" Title="<#= AppInfo.Product + " " + AppInfo.Edition #>" RuntimeType="XNA" Version="<#= AppInfo.Version #>" Genre="apps.games" Author="Gonzo" Description="<#= AppInfo.Description #>" Publisher="<#= AppInfo.Company #>">
        ...
    </App>
</Deployment>

在上面的代码片段中，我在程序集指令中指定了 $（TargetPath）（这指向我在 bin 目录中编译的程序集），最终我能够从 AssemblyInformation 中查看自定义属性。这样，我只定义一次 Guid 和其他所需数据 - 这是我的 AssemblyInformation 的一部分：

...
#if !LITE_EDITION
[assembly: Guid("716ab9de-f88e-9a14-8d81-65sn67dbf99e")]
[assembly: AssemblyEdition("Pro")]
#else
[assembly: Guid("91e6742f-6273-1a8b-55a69-e70ad5644827")]
[assembly: AssemblyEdition("Lite")]
#endif
...

根据当前配置（例如调试、调试精简版、发布、发布精简版），我会生成包含正确信息的应用清单。我希望这有所帮助。
