Get comparison results

You can get project comparison results (IModelComparison type) using the GetComparison method of the IDiff object. The GetComparison method gets the most recent comparison result for the specified project.

tip

The GetComparison method can also get the comparison result being displayed in the UI.

You can also get comparison information for a specified model using the GetMatch method of the IModelComparison object.

public void GetDifference(ICommandContext c, ICommandParams p) 
{ 
//Get the comparison result for the current project 
var project = c.App.Workspace.CurrentProject; 
IModelComparison comparison = c.App.Diff.GetComparison(project); 

//Output the difference information for the current model 
var model = c.App.Workspace.CurrentModel; 
IMatch match = comparison.GetMatch(model); 

if (!match.HasDifference) 
{ 
c.App.Output.WriteLine("Show Diff", "There are no differences."); 
return; 
} 

foreach (IDifference difference in match.Differences) 
{ 
if (difference.IsNewItem) 
{ 
c.App.Output.WriteLine("Show Diff", "This is the model you added."); 
} 
if (difference.IsUpdateItem) 
{ 
c.App.Output.WriteLine("Show Diff", $"Field: {difference.Field} was updated from {difference.OldValue} to {difference.NewValue}."); 
} 
} 
}
