Adding an attribute to a project item

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");  
}
