Manage MS Project Outline Values with Aspose.Tasks

Introduction

Aspose.Tasks for .NET provides a comprehensive set of features to interact with Microsoft Project files. One such feature is the ability to manage outline values within a project. In this tutorial, we will explore how to collect and manipulate outline values using Aspose.Tasks for .NET.

Prerequisites

Before we begin, ensure you have the following:

1. Aspose.Tasks for .NET: You can download the library from here.
2. Development Environment: Make sure you have a suitable IDE installed, such as Visual Studio.
3. Basic Knowledge of C#: Familiarity with C# programming language will be beneficial.

Import Namespaces

In your C# code file, import the necessary namespaces to access Aspose.Tasks classes and methods:

using Aspose.Tasks;
using System;

Let’s break down the provided example into multiple steps:

Step 1: Load a Project File

Firstly, initialize a Project object by loading an existing Microsoft Project file:

string DataDir = "Your Document Directory";
var project = new Project(DataDir + "OutlineValues2010.mpp");

Step 2: Clear Existing Outline Values

Next, clear any existing outline values from the project:

foreach (var outlineCode in project.OutlineCodes)
{
    if (outlineCode.Values.Count <= 0)
    {
        continue;
    }
    if (!outlineCode.Values.IsReadOnly)
    {
        outlineCode.Values.Clear();
    }
}

Step 3: Define New Outline Code

Now, define a new outline code with a description and value:

var codeDefinition = new OutlineCodeDefinition
{
    Alias = "New task outline code1",
    FieldId = ((int)ExtendedAttributeTask.OutlineCode1).ToString(),
    FieldName = "Outline Code1"
};
var value = new OutlineValue { Description = "Value description", ValueId = 1, Value = "123456", Type = OutlineValueType.Number };
codeDefinition.Values.Add(value);
project.OutlineCodes.Add(codeDefinition);

Step 4: Update Outline Value

Update the value of the outline code:

codeDefinition.Values[0].Value = "654321";

Step 5: Iterate Over Outline Values

Iterate through the outline values and print their details:

foreach (var definitionValue in codeDefinition.Values)
{
    Console.WriteLine("Value: " + definitionValue.Value);
    Console.WriteLine("Value Id: " + definitionValue.ValueId);
    Console.WriteLine("Value Guid: " + definitionValue.ValueGuid);
    Console.WriteLine();
}

Step 6: Manipulate Outline Values

Perform operations like removing, inserting, and copying outline values as needed:

if (codeDefinition.Values.Contains(value))
{
    codeDefinition.Values.Remove(value);
}
codeDefinition.Values.Insert(0, value);
Console.WriteLine("Index of inserted value: " + codeDefinition.Values.IndexOf(value));
codeDefinition.Values.RemoveAt(codeDefinition.Values.Count - 1);
var codeDefinition2 = new OutlineCodeDefinition
{
    Alias = "New outline code 2",
    FieldId = ((int)ExtendedAttributeTask.OutlineCode2).ToString(),
    FieldName = "Outline Code2"
};
var outlineValues = new OutlineValue[codeDefinition.Values.Count];
codeDefinition.Values.CopyTo(outlineValues, 0);
foreach (var outlineValue in outlineValues)
{
    codeDefinition2.Values.Add(outlineValue);
}

Conclusion

In this tutorial, we learned how to work with outline values in Microsoft Project files using Aspose.Tasks for .NET. By following the provided steps, you can efficiently manage outline values within your projects, enabling greater control and flexibility.
