Create SharePoint List Programmatically

Create a SharePoint list programmatically in C#.

Add lookup field for our newly created list.

This is a sample code.

public void createList()
{
    // choose your site
    SPSite site = new SPSite("http://merdev-moss:5050");
    SPWeb web = site.OpenWeb();
    SPListCollection lists = web.Lists;

    // create new Generic list called "My List"

    lists.Add("My List", "My list Description", SPListTemplateType.GenericList);

 

    SPList newList = web.Lists["My List"];

    // create Text type new column called "My Column"
    newList.Fields.Add("My Column", SPFieldType.Text, true);

    /*create lookup type new column called "Lookup Column"
    * Here I am going to get the information from the "Title"
    * column of a list called "User Roles"
    */
    SPList targetList = web.Lists["User Roles"];

    newList.Fields.AddLookup("Lookup Column", targetList.ID, false);
    SPFieldLookup lkp = (SPFieldLookup)newList.Fields["Lookup Column"];
    lkp.LookupField = targetList.Fields["Title"].InternalName;
    lkp.Update();

    // make new column visible in default view
    SPView view = newList.DefaultView;
    view.ViewFields.Add("My Column");
    view.ViewFields.Add("Lookup Column");
    view.Update();
}
