SPD Workflow activity : Creating a document library

Using the codesample of Todd Baginski's post of creating a custom activity to email, I modified the code to create a doclib using two variables that an user enters in SPD. These two variables are the url of the site and the title of the document library.

I replaced the code of Todd with this chunk :

using System;

using System.ComponentModel;

using System.ComponentModel.Design;

using System.Collections;

using System.Diagnostics;

using System.Drawing;

using System.Workflow.ComponentModel;

using System.Workflow.ComponentModel.Design;

using System.Workflow.ComponentModel.Compiler;

using System.Workflow.ComponentModel.Serialization;

using System.Workflow.Runtime;

using System.Workflow.Activities;

using System.Workflow.Activities.Rules;

using Microsoft.SharePoint;

namespace CreateDocumentLibrary

{

    public partial class Doclib: SequenceActivity

    {

        private EventLog _eventLog; 

        public static DependencyProperty UrlProperty = 
DependencyProperty.Register("Url", typeof(string), typeof(Doclib));

        public static DependencyProperty ListNameProperty = 
DependencyProperty.Register("ListName", typeof(string), typeof(Doclib));

        [ValidationOption(ValidationOption.Required)]

        public string Url

        {

            get

            {

                return (string)base.GetValue(UrlProperty);

            }

            set

            {

                base.SetValue(UrlProperty, value);

            }

        }

        [ValidationOption(ValidationOption.Required)]

        public string ListName

        {

            get

            {

                return (string)base.GetValue(ListNameProperty);

            }

            set

            {

                base.SetValue(ListNameProperty, value);

            }

        }

        protected override ActivityExecutionStatus 
Execute(ActivityExecutionContext executionContext)

        {

            //Set up the Event Logging object 

            _eventLog = new EventLog("Workflow");

            _eventLog.Source = "SharePoint Workflow";

            try

            {

                //Send the email 

                CreateList();

            }

            finally

            {

                //Dispose of the Event Logging object 

                _eventLog.Dispose();

            }

            //Indicate the activity has closed 

            return ActivityExecutionStatus.Closed;

        }

        private void CreateList()

        {

            try

            {

            SPSite site = new SPSite(Url);

            SPWeb rootweb = site.OpenWeb();

            SPListCollection lists = rootweb.Lists;

            SPListTemplateType listTemplateType = new SPListTemplateType();

            listTemplateType = SPListTemplateType.DocumentLibrary;

            lists.Add(ListName, "", listTemplateType);

         _eventLog.WriteEntry("Worklow succes: List 
created at: " + rootweb.Title.ToString());

            }

            catch (System.Exception Ex)

            {

                //Log exceptions in the Event Log 

                _eventLog.WriteEntry("Workflow Error :" + 
Ex.Message.ToString(), EventLogEntryType.Information);

            }

        } 

        public Doclib()

        {

            InitializeComponent();

        }

    }

}

And the XML to publish this code in SPD in the WSS.ACTIONS looks like:

<Action Name="Create Document Library"
ClassName="CreateDocumentLibrary.Doclib"
Assembly="CreateDocumentLibrary, Version=1.0.0.0, Culture=neutral, PublicKeyToken=54d1a6fdf526a294"
AppliesTo="all"
Category="Sample">
<RuleDesigner Sentence="Create document library %1 on %2.">
<FieldBind Field="Url" Text="Link to site" DesignerType="TextArea" Id="1"/>
<FieldBind Field="ListName" Text="Name of the doclib" Id="2" DesignerType="TextArea"/>
</RuleDesigner>
<Parameters>
<Parameter Name="Url" Type="System.String, mscorlib" Direction="In" />
<Parameter Name="ListName" Type="System.String, mscorlib" Direction="In" />
</Parameters>
</Action>

</Actions>

So if you want use this code, follow all the steps that are described in the post of Todd and replace his code and xml with mine and you could be a happy man! ;)
