My twelfth How do I is up.
Scenario
Let’s say that we have a DTE project instance and we want to get the project GUID. If we look carefully the EnvDTE.Project interface doesn’t have a guid property. To obtain it we need to first obtain the corresponding IVsHierarchy for the project and then query the guid property. The focus of this How do I tackles this scenario.
Interfaces and classes needed
Code snippet
public Guid GetProjectGuid(IServiceProvider serviceProvider, Project project)
{
var solution = serviceProvider.GetService(typeof(SVsSolution)) as IVsSolution;
IVsHierarchy hierarchy;
solution.GetProjectOfUniqueName(project.FullName, out hierarchy);
if(hierarchy != null)
{
Guid projectGuid;
ErrorHandler.ThrowOnFailure(
hierarchy.GetGuidProperty(
VSConstants.VSITEMID_ROOT,
(int)__VSHPROPID.VSHPROPID_ProjectIDGuid,
out projectGuid));
if(projectGuid != null)
{
return projectGuid;
}
}
return Guid.Empty;
}
Assemblies needed
- Microsoft.VisualStudio.Shell.Interop, Version=7.1.40304.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
Stay tuned,
Pablo
