I'm developing a custom tool for the Visual Studio. The tool is assigned to the file, at the time when the file changed I receive name of this file and should generate some changes in the project. I need to find a ProjectItem by the received file name. I have found only one solution it's enumerate all project items in the each project of the solution. But it seems to be huge solution. Is there a way to get a project item by the file name without enumeration?
This is my implementation of the Generate method of the IVsSingleFileGenerator
public int Generate(string sourceFilePath, string sourceFileContent, string defaultNamespace, IntPtr[] outputFileContents, out uint output, IVsGeneratorProgress generateProgress)
{
var dte = (EnvDTE.DTE)Package.GetGlobalService(typeof(EnvDTE.DTE));
ProjectItem projectItem = null;
foreach (Project project in dte.Solution.Projects)
{
foreach (ProjectItem item in project.ProjectItems)
{
var path = item.Properties.Item("FullPath").Value;
if (sourceFilePath.Equals(path, StringComparison.OrdinalIgnoreCase))
{
projectItem = item;
}
}
}
output = 0;
outputFileContents[0] = IntPtr.Zero;
return Microsoft.VisualStudio.VSConstants.S_OK;
}
I am using this user-friendly world of DTE as well, to create a Guidance. I did not find any better solution. Basically these are methods I am using:
Iterate projects:
public static ProjectItem FindSolutionItemByName(DTE dte, string name, bool recursive)
{
ProjectItem projectItem = null;
foreach (Project project in dte.Solution.Projects)
{
projectItem = FindProjectItemInProject(project, name, recursive);
if (projectItem != null)
{
break;
}
}
return projectItem;
}
Find in a single project:
public static ProjectItem FindProjectItemInProject(Project project, string name, bool recursive)
{
ProjectItem projectItem = null;
if (project.Kind != Constants.vsProjectKindSolutionItems)
{
if (project.ProjectItems != null && project.ProjectItems.Count > 0)
{
projectItem = DteHelper.FindItemByName(project.ProjectItems, name, recursive);
}
}
else
{
// if solution folder, one of its ProjectItems might be a real project
foreach (ProjectItem item in project.ProjectItems)
{
Project realProject = item.Object as Project;
if (realProject != null)
{
projectItem = FindProjectItemInProject(realProject, name, recursive);
if (projectItem != null)
{
break;
}
}
}
}
return projectItem;
}
The code I am using with more snippets could be found here, as a Guidance for new projects. Search for and take the source code..
