在 Visual Studio 中添加 - 如何检索文本选择对象的属性 (Visual Commander)

Question

我为此挠了一天多：

基本上我正在尝试为 Visual Studio 2012 构建一个加载项，它执行以下操作：

取当前选择的变量名，找到它作为实例的类，然后在自己的行中为每个属性键入veriable.property：

之前：

例如。 （考虑选择了 myPerson）

int CountPerson(Person myPerson)
{
    *myPerson*
}

之后：

int CountPerson(Person myPerson)
{
    myPerson.Name
    myPerson.Surname
    myPerson.Age
}

我在 stackoverflow 上问了一个类似的问题，并得到了我现在正在追求的答案。 Visual Studio dump all properties of class into editor

这是目前为止的源代码：

using EnvDTE;
using EnvDTE80;
using System;
using System.ComponentModel;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;


public class C : VisualCommanderExt.ICommand
{
    public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package) 
    {
        EnvDTE.TextSelection ts = DTE.ActiveWindow.Selection as EnvDTE.TextSelection;
        if (ts == null)
            return;

        EnvDTE.CodeClass codeClass = ts.ActivePoint.CodeElement[vsCMElement.vsCMElementClass]   as     EnvDTE.CodeClass;
        if (codeClass == null)
            return;

        string properties = "";
        foreach (CodeElement elem in codeClass.Members)
        {
            if (elem.Kind == vsCMElement.vsCMElementProperty)
                properties += elem.Name + System.Environment.NewLine;
        }
        ts.Text = properties;   

    }
}

这工作得很好，除了它完全忽略选定的文本，而是打印当前类的属性。我需要我选择的变量的类的属性。

如果这样会让事情变得更容易的话，我会接受输入“Person”而不是 |myPerson。

我在互联网上找到了以下链接，但无法实现逻辑： http://blogs.clariusconsulting.net/kzu/how-to-get-a-system-type-from-an-envdte-codetyperef-or-envdte-codeclass/ http://www.visualstudioextensibility.com/2008/03/06/how-do-i-get-a-system-type-from-a-type-name/

他们可能会帮助你帮助我吗？

您可以将光标设置在函数定义行中的函数参数名称上，并使用以下代码生成属性列表：

（添加对 Microsoft.VisualStudio.Shell.Design 的引用）

public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package) 
{
    EnvDTE.TextSelection ts = DTE.ActiveWindow.Selection as EnvDTE.TextSelection;
    if (ts == null)
        return;

    EnvDTE.CodeParameter codeParam = ts.ActivePoint.CodeElement[vsCMElement.vsCMElementParameter] as EnvDTE.CodeParameter;
    if (codeParam == null)
        return;

    System.Type tClass = GetTypeByName(DTE, package, codeParam.Type.AsFullName);
    string properties = "";
    foreach (var p in tClass.GetProperties())
    {
            properties += codeParam.Name + "." + p.Name + System.Environment.NewLine;
    }
    System.Windows.Clipboard.SetText(properties);
    System.Windows.MessageBox.Show(properties);
}

private System.Type GetTypeByName(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package, string name)
{
    System.IServiceProvider serviceProvider = package as System.IServiceProvider;
    Microsoft.VisualStudio.Shell.Design.DynamicTypeService typeService = 
        serviceProvider.GetService(typeof(Microsoft.VisualStudio.Shell.Design.DynamicTypeService)) as
        Microsoft.VisualStudio.Shell.Design.DynamicTypeService;

    Microsoft.VisualStudio.Shell.Interop.IVsSolution sln = 
        serviceProvider.GetService(typeof(Microsoft.VisualStudio.Shell.Interop.IVsSolution)) as
        Microsoft.VisualStudio.Shell.Interop.IVsSolution;

    Microsoft.VisualStudio.Shell.Interop.IVsHierarchy hier;
    sln.GetProjectOfUniqueName(DTE.ActiveDocument.ProjectItem.ContainingProject.UniqueName, out hier);

    return typeService.GetTypeResolutionService(hier).GetType(name, true);
}

好的，感谢上面的 Sergey，我现在有了以下代码，可以回答我的大部分问题：

using EnvDTE;
using EnvDTE80;
using System;

public class C : VisualCommanderExt.ICommand
{
        public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package) 
        {
            EnvDTE.TextSelection ts = DTE.ActiveWindow.Selection as EnvDTE.TextSelection;
            if (ts == null)
                    throw new Exception("No Selection");

                EnvDTE.CodeParameter codeParam = ts.ActivePoint.CodeElement[vsCMElement.vsCMElementParameter] as EnvDTE.CodeParameter;
                if (codeParam == null)
                    throw new Exception("Not Parameter");

                System.Type tClass = GetTypeByName(DTE, package, codeParam.Type.AsFullName);
                string properties = System.Environment.NewLine;
                foreach (var p in tClass.GetProperties())
                {
                    properties += codeParam.Name + "." + p.Name + System.Environment.NewLine;
                }

                // Move into the method and dump the properties there
                ts.FindText("{");
                ts.Insert("{" + properties);
            }


    private System.Type GetTypeByName(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package, string name)
    {
        System.IServiceProvider serviceProvider = package as System.IServiceProvider;
        Microsoft.VisualStudio.Shell.Design.DynamicTypeService typeService = 
            serviceProvider.GetService(typeof(Microsoft.VisualStudio.Shell.Design.DynamicTypeService)) as
                Microsoft.VisualStudio.Shell.Design.DynamicTypeService;

        Microsoft.VisualStudio.Shell.Interop.IVsSolution sln = serviceProvider.GetService(typeof(Microsoft.VisualStudio.Shell.Interop.IVsSolution)) as
            Microsoft.VisualStudio.Shell.Interop.IVsSolution;

        Microsoft.VisualStudio.Shell.Interop.IVsHierarchy hier;
        sln.GetProjectOfUniqueName(DTE.ActiveDocument.ProjectItem.ContainingProject.UniqueName, out hier);

        return typeService.GetTypeResolutionService(hier).GetType(name, true);
    }
}
