Examples

Shows how to work with risk pattern collections.

var settings = new RiskAnalysisSettings
{
    // Set number of iterations for Monte Carlo simulation (the default value is 100).
    IterationsCount = 200
};

var project = new Project(DataDir + "Software Development Plan-1.mpp");
var task1 = project.RootTask.Children.GetById(17);
var task2 = project.RootTask.Children.GetById(18);

// as far as RiskPatternCollection is not a read-only
Console.WriteLine("Is pattern collection read-only?: " + settings.Patterns.IsReadOnly);

// one can add new patterns

    Optimistic = 70,
    Pessimistic = 130,
    ConfidenceLevel = ConfidenceLevel.CL75
};

settings.Patterns.Add(pattern1);
settings.Patterns.Add(pattern2);

// iterate over added patterns
Console.WriteLine("Patterns count: " + settings.Patterns.Count);

    Console.WriteLine("Task: " + pattern.Task);

    Console.WriteLine("Pessimistic: " + pattern.Pessimistic);

// edit the pattern in the collection by using index access

    Console.WriteLine("Pessimistic: " + pattern.Pessimistic);
    Console.WriteLine("Confidence Level: " + pattern.ConfidenceLevel);
    Console.WriteLine();

// we can remove the pattern
Console.WriteLine("Removing the first pattern...");
settings.Patterns.Remove(pattern1);

// check that pattern not in the collection

settings.Patterns.CopyTo(patterns, 0);
foreach (var pattern in patterns)
{
    settings.Patterns.Remove(pattern);

// or one can clear a pattern collection completely
settings.Patterns.Clear();
