Examples

Shows how to use extended attribute definition collections.

var project = new Project(DataDir + "ReadTaskExtendedAttributes.mpp");

if (!project.ExtendedAttributes.IsReadOnly)
{
    if (project.ExtendedAttributes.Count > 0)
    {
        // clear extended attribute definitions
        project.ExtendedAttributes.Clear();
    }
}

// create extended attribute definition for a task
var taskDefinition = ExtendedAttributeDefinition.CreateTaskDefinition(CustomFieldType.Start, ExtendedAttributeTask.Start7, "Start 7");
project.ExtendedAttributes.Add(taskDefinition);

Console.WriteLine("Iterate over extended attributes of " + project.ExtendedAttributes.ParentProject.Get(Prj.Name) + " project: ");
foreach (var attribute in project.ExtendedAttributes)
{
    Console.WriteLine("Attribute Alias: " + attribute.Alias);
    Console.WriteLine("Attribute CfType: " + attribute.CfType);
    Console.WriteLine();
}

Console.WriteLine();

// work with extended attribute definitions...
var resourceDefinition = ExtendedAttributeDefinition.CreateResourceDefinition(CustomFieldType.Cost, ExtendedAttributeResource.Cost5, "My cost");

if (!project.ExtendedAttributes.Contains(resourceDefinition))
{
    project.ExtendedAttributes.Add(resourceDefinition);
}

// work with extended attribute definitions...
var resourceDefinition2 = ExtendedAttributeDefinition.CreateResourceDefinition(CustomFieldType.Number, ExtendedAttributeResource.Cost1, "My Cost 2");

if (project.ExtendedAttributes.IndexOf(resourceDefinition2) < 0)
{
    project.ExtendedAttributes.Insert(0, resourceDefinition2);
}

// work with extended attribute definitions...

// remove extended attribute by index
project.ExtendedAttributes.RemoveAt(0);

Console.WriteLine("Print project's extended attributes: ");
Console.WriteLine("Count of project's extended attribute definitions: " + project.ExtendedAttributes.Count);

// use collection index access
Console.WriteLine("Attribute 1 Alias: " + project.ExtendedAttributes[0].Alias);

Console.WriteLine("Attribute 2 Alias: " + project.ExtendedAttributes[1].Alias);
Console.WriteLine("Attribute 2 CfType: " + project.ExtendedAttributes[1].CfType);

var otherProject = new Project();

// copy attributes to other project
var attributes = new ExtendedAttributeDefinition[project.ExtendedAttributes.Count];
project.ExtendedAttributes.CopyTo(attributes, 0);

foreach (var attribute in attributes)
{
    otherProject.ExtendedAttributes.Add(attribute);
}

Console.WriteLine();
Console.WriteLine("Iterate over other project's extended attributes: ");
foreach (var attribute in otherProject.ExtendedAttributes)
{
    Console.WriteLine("Attribute Alias: " + attribute.Alias);
    Console.WriteLine("Attribute CfType: " + attribute.CfType);
    Console.WriteLine();

// remove all extended attribute definitions
