]Like Tasks and Resources, Extended Attributes can be added to Resource Assignments as well. Aspose.Tasks for .NET API lets you add Extended Attributes to Resource Assignments. Extended Attributes can be added to Resource Assignments as plain as well as Lookup attributes.
Adding Extended Attributes to Resource Assignment
1// Create new project
2Project project = new Project("New Project.mpp");
3
4// Add new task and resource
5Task task = project.RootTask.Children.Add("Task");
6Resource resource = project.Resources.Add("Rsc");
7
8// Assign the resource to the desired task
9ResourceAssignment assignment = project.ResourceAssignments.Add(task, resource);
10
11// Custom attributes which is visible in "Resource Usage" view can be created with ExtendedAttributeDefinition.CreateResourceDefinition method.
12{
13 ExtendedAttributeDefinition resCostAttributeDefinition = ExtendedAttributeDefinition.CreateResourceDefinition(
14 CustomFieldType.Cost,
15 ExtendedAttributeResource.Cost5,
16 "My cost");
17
18 project.ExtendedAttributes.Add(resCostAttributeDefinition);
19
20 var value = resCostAttributeDefinition.CreateExtendedAttribute();
21
22 // The type of the attribute is "Cost", so we need to use "NumericValue" property.
23 value.NumericValue = 1500;
24
25 assignment.ExtendedAttributes.Add(value);
26}
27
28// Custom attributes which is visible in "Task Usage" view can be created with ExtendedAttributeDefinition.CreateTaskDefinition method
29{
30 ExtendedAttributeDefinition taskCostAttributeDefinition = ExtendedAttributeDefinition.CreateTaskDefinition(
31 CustomFieldType.Cost,
32 ExtendedAttributeTask.Cost5,
33 "My cost for task");
34
35 project.ExtendedAttributes.Add(taskCostAttributeDefinition);
36
37 var value = taskCostAttributeDefinition.CreateExtendedAttribute();
38
39 // The type of the attribute is "Cost", so we need to use "NumericValue" property.
40 value.NumericValue = 2300;
41
42 assignment.ExtendedAttributes.Add(value);
43}

45project.Save("AddExtendedAttributesToResourceAssignment_out.mpp", SaveFileFormat.MPP);Adding Lookup Extended Attributes to Resource Assignment
1// Create new project
2Project project = new Project("New Project.mpp");
3
4// Assign resource "1 TRG: Trade Group" to the "TASK 1" by creating a ResourceAssignment object.
5Resource resource = project.Resources.GetById(1);
6Task task = project.RootTask.Children.GetById(1);
7
8ResourceAssignment assignment = project.ResourceAssignments.Add(task, resource);

10// Create custom attribute definition with lookup.
11ExtendedAttributeDefinition resCostAttr = ExtendedAttributeDefinition.CreateLookupResourceDefinition(
12 CustomFieldType.Cost,
13 ExtendedAttributeResource.Cost5,
14 "My lookup resource cost");

19resCostAttr.AddLookupValue(value1);
20
21resCostAttr.AddLookupValue(new Value { NumberValue = 2500, Description = "Val 2", Id = 2 });
22
23// This value can be seen in "Resource usage" view of MS Project.
24var attributeValue = resCostAttr.CreateExtendedAttribute(value1);
25assignment.ExtendedAttributes.Add(attributeValue);
26
27// Create custom attribute definition with lookup.
28ExtendedAttributeDefinition taskCostAttr = ExtendedAttributeDefinition.CreateLookupTaskDefinition(
29 ExtendedAttributeTask.Cost4,
30 "My lookup task cost");
31
32project.ExtendedAttributes.Add(taskCostAttr);

34var taskLookupValue1 = new Value { NumberValue = 18, Description = "Task val 1", Id = 3, Val = "18" };
35taskCostAttr.AddLookupValue(taskLookupValue1);
