Get diff

This explains how to get diff information for a project.

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

//Get the comparison information that extracts the differences 
IMatchCollection matches = comparison.GetDifferencedMatches(); 
foreach (IMatch match in matches) 
{ 
foreach (IDifference difference in match.Differences) 
{ 
if (difference.IsNewItem) 
{ 
//For additional differences, get the added model with IMatch.Reference 
IModel model = match.Reference; 
c.App.Output.WriteLine("Show Diff", $"{model.Name} has been added."); 
} 
if (difference.IsOldItem) 
{ 
//In the case of deletion diff, the deleted model is obtained with IMatch.Target 
IModel model = match.Target; 
c.App.Output.WriteLine("Show Diff", $"{model.Name} has been deleted."); 
} 
if (difference.IsUpdateItem) 
{ 
IModel model = match.Reference; 
c.App.Output.WriteLine("Show Diff", $"Field: {difference.Field} of {model.Name} has been updated from {difference.OldValue} to {difference.NewValue}."); 
} 
} 
}
