Managing Resource Extended Attributes

The ExtendedAttribute property exposed by the Resource class can be used to manage the extended attributes of a resource. This property reads and writes an ArrayList of the ExtendedAttribute objects to deal with a resource’s extended attributes. The ExtendedAttribute object further exposes the relevant properties.

Setting Extended Resource Attributes with Aspose.Tasks

The following code example demonstrates how to set a resource’s extended attributes.

Project project = new Project("New Project.mpp");

// Define extended attribute
ExtendedAttributeDefinition myNumber1 = project.ExtendedAttributes.GetById((int)ExtendedAttributeTask.Number1);
if (myNumber1 == null)
{
    myNumber1 = ExtendedAttributeDefinition.CreateResourceDefinition(ExtendedAttributeResource.Number1, "Age");
    project.ExtendedAttributes.Add(myNumber1);
}

// Create extended attribute and set its value
ExtendedAttribute number1Resource = myNumber1.CreateExtendedAttribute();
number1Resource.NumericValue = 30.5345m;

// Add a new resource and its extended attribute   
Resource resource = project.Resources.Add("R1");
resource.ExtendedAttributes.Add(number1Resource);

project.Save("ResourceExtendedAttributes_out.mpp", SaveFileFormat.MPP);
