如何从 Visual Studio 扩展和新的 csproj 格式中获取 IntermediateOutputPath

Question

我有一个覆盖 IntermediateOutputPath 的新样式 csproj 项目文件。它看起来像这样：

<PropertyGroup>
    <TargetFramework>netstandard1.6</TargetFramework>
    <IntermediateOutputPath>new\path\to\obj</IntermediateOutputPath>
</PropertyGroup>

问题是，我的 Visual Studio 分机无法访问 IntermediateOutputPath 属性。 Project.Properties 与旧项目格式相比，内容似乎少了很多。

我也试过 project.ConfigurationManager.ActiveConfiguration.Properties 也取得了类似的成功。

有什么方法可以从 Visual Studio 扩展程序中获取此信息？

所以我创建了一个简单的扩展来打印所有属性

    private string GetPropertiesString(Properties properties)
    {
        StringBuilder test = new StringBuilder();
        foreach (Property property in properties)
        {
            try
            {
                test.AppendLine(property.Name + ":=" + property.Value.ToString());
                Console.WriteLine(property.Name + ":=" + property.Value.ToString());
            }
            catch (Exception ex)
            {
                var x = ex.Message;
            }
        }

        return test.ToString();
    }

    private void MenuItemCallback(object sender, EventArgs e)
    {
        DTE2 dte2 = Package.GetGlobalService(typeof(DTE)) as DTE2;
        var sol = dte2.Solution;
        var projs = sol.Projects;
        foreach (var proj in sol)
        {
            var project = proj as Project;
            var rows = project.ConfigurationManager.ConfigurationRowNames as IEnumerable<object>;
            foreach (var row in rows)
            {
                var config = project.ConfigurationManager.ConfigurationRow(row.ToString()).Item(1) as Configuration;
                string configs = GetPropertiesString(config.Properties);
            }
        }
    }

这给出了以下输出

在我添加的CS项目中

<IntermediateOutputPath>new\path\to\obj2</IntermediateOutputPath>

如您所见，IntermediateOutputPath 即将成为 IntermediatePath。所以你可以使用

var config = project.ConfigurationManager.ConfigurationRow("Debug").Item(1) as Configuration;
config.Properties.Item("IntermediatePath").Value

因此，在深入研究该问题后，我发现属性本身就是一个 MSBuild 属性，而不是与 CSProject 相关的属性。这就是您在 Properties 属性中看不到它的原因。这需要稍微不同的方向才能使用 IVsBuildPropertyStorage.GetPropertyValue

获取值

    private IVsBuildPropertyStorage GetBuildPropertyStorage(EnvDTE.Project project)
    {
        IVsSolution solution = (IVsSolution)ServiceProvider.GetService(typeof(SVsSolution));

        IVsHierarchy hierarchy;
        int hr = solution.GetProjectOfUniqueName(project.FullName, out hierarchy);
        System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(hr);

        return hierarchy as IVsBuildPropertyStorage;
    }

    private string GetBuildProperty(string key, IVsBuildPropertyStorage Storage)
    {
        string value;
        int hr = Storage.GetPropertyValue(key, null, (uint)_PersistStorageType.PST_USER_FILE, out value);
        int E_XML_ATTRIBUTE_NOT_FOUND = unchecked((int)0x8004C738);

        // ignore this HR, it means that there's no value for this key
        if (hr != E_XML_ATTRIBUTE_NOT_FOUND)
        {
            System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(hr);

        }

        return value;
    }

然后再使用这些方法获取值

var project = proj as EnvDTE.Project;
IVsBuildPropertyStorage storage = GetBuildPropertyStorage(project);
string outputPath = GetBuildProperty("IntermediateOutputPath", storage);

这给了我属性

的正确值
