【问题描述】：

我正在开发一个 Visual Studio 扩展包。每次我测试运行时，都会打开一个 VS 的实验实例。我在实验实例中创建了一个项目；如何获取实验实例中创建的项目的路径？

【解决方案1】：

鉴于代表项目层次结构的IVsHierarchy 对象，您可以在使用VSHPROPID_ProjectDir / VSHPROPID_Name properties 调用GetProperty 方法时使用VSITEMID_ROOT id。

或者，如果您有EnvDTE.Project，则可以使用EnvDTE.Project.FullName 属性。

【解决方案2】：

首先应该导入 EnvDTE（在 EnvDTE.dll 中）。然后我声明了属性 ProejectFullName

string ProejectFullName{ get; }

表示项目对象文件的完整路径和名称的字符串。

public void GetmyFilePath(DTE2 dte)

{  
    try
    {   // Open a project before running this sample.
        Project prj = dte.Solution.Projects.Item(1);
        Projects prjs;


string msg, msg2 = "Global Variables:";
    msg = "FileName: " + prj.FileName;
    msg += "\nProejectFullName: " + prj.ProejectFullName;
    msg += "\nProject-level access to " + prj.CodeModel.CodeElements.Count.ToString() +
        " CodeElements through the CodeModel";
    prjs = prj.Collection;
    msg += "\nThere are " + prjs.Count.ToString() + " projects in the same collection.";
    msg += "\nApplication containing this project: " + prj.DTE.Name;
    if (prj.Saved)
        msg += "\nThis project hasn't been modified since the last save.";
    else
        msg += "\nThis project has been modified since the last save.";
    msg += "\nProperties: ";
    foreach (Property prop in prj.Properties)
    {
        msg += "\n  " + prop.Name;
    }
    foreach (String s in (Array)prj.Globals.VariableNames)
    {
        msg2 += "\n  " + s;
    }

    MessageBox.Show(msg, "Project Name: " + prj.Name);
    MessageBox.Show(msg2);
}
catch(Exception ex)
{
    MessageBox.Show(ex.Message);
}
}
