Adding an Attribute to a Project Item

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at Adding an Attribute to a Project Item.

The methods GetItemAttribute and SetItemAttribute get and set the value of the attributes of a project item. SetItemAttribute creates the attribute if it does not already exist, adding it to the project item metadata.

To add an attribute to a project item

• The following code uses the DTE automation object and the SetItemAttribute method to add an attribute to a project item. The project item ID is obtained from the project item name "program.cs". The attribute "MyAttribute" is added to this project item and given the value "MyValue".

  EnvDTE.DTE dte = (EnvDTE.DTE)Package.GetGlobalService(typeof(EnvDTE.DTE));  
  EnvDTE.Project project = dte.Solution.Projects.Item(1);  
  
  string uniqueName = project.UniqueName;  
  IVsSolution solution =     (IVsSolution)Package.GetGlobalService(typeof(SVsSolution));  
  IVsHierarchy hierarchy;  
  solution.GetProjectOfUniqueName(uniqueName, out hierarchy);  
  IVsBuildPropertyStorage buildPropertyStorage = hierarchy as IVsBuildPropertyStorage;  
  if (buildPropertyStorage != null)  
  {  
      uint itemId;  
      string fullPath =         (string)project.ProjectItems.Item("Program.cs").Properties.Item("FullPath").Value;  
      hierarchy.ParseCanonicalName(fullPath, out itemId);  
      buildPropertyStorage.SetItemAttribute(  
          itemId, "MyAttribute", "MyValue");  
  }
