读取和更改项目属性“启动外部程序”和“命令行参数”

Question

I'm trying to read (and change) the project properties "Start external program" and "Command line arguments" of a VisualStudio 2013 project within a VSPackage. The code I wrote so far looks like:

var dte = GetService(typeof(DTE)) as DTE2;
if (dte == null)
    return;

var sb = (SolutionBuild2)dte.Solution.SolutionBuild;
var projectNames = sb.StartupProjects as Array;
if (projectNames == null || projectNames.Length == 0)
  return;

var project = dte.Solution.Item(projectNames.GetValue(0));
var config = project.ConfigurationManager.ActiveConfiguration;

But I can't find the two spcific properties neither in the project nor in the config .

Answer 1

The EnvDTE.Configuration class has a Properties collection that has your desired values:

config.Properties.Item("StartProgram").Value

config.Properties.Item("StartArguments").Value

FWIW, the VSLangProj.dll assembly has a VSLangProj.ProjectConfigurationProperties class with the property names that you can expect in the config.Properties collection.
