I'm trying to create a sharepoint list following the example on Microsofts documentation

// Dependencies
using Microsoft.Graph.Models;

var requestBody = new List
{
DisplayName = "Books",
Columns = new List<ColumnDefinition>
{
    new ColumnDefinition
    {
        Name = "Author",
        Text = new TextColumn
        {
        },
    },
    new ColumnDefinition
    {
        Name = "PageCount",
        Number = new NumberColumn
        {
        },
    },
},
List = new ListInfo
{
    Template = "genericList",
},
};

var result = await graphClient.Sites["{site-id}"].Lists.PostAsync(requestBody);

However the compiler marks the line

List = new ListInfo

with 'List' does not contain a definition for 'List' (CS0117)

Quickfix suggests changing it to ListProp. That compiles but on runtime that produces an Invalid Request as does ommiting that entry.

• The issue you're encountering arises from a mismatch between the property name you're trying to use (List) and what the Microsoft Graph API expects for creating a new SharePoint list. Based on the documentation and the structure of ListInfo, the correct property name is actually ListInfo (or ListTemplate in some contexts), not List. – Rukmini Commented Nov 19, 2024 at 12:23
• Tried them both already. Won't compile either. – Roest Commented Nov 19, 2024 at 12:29

To create SharePoint list, you need to make use of ListProp instead of List:

class Program
{
    private static async Task Main(string[] args)
    {
        string tenantId = "TenantID";
        string clientId = "ClientID";
        string clientSecret = "ClientSecret";

        var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret);
        var graphClient = new GraphServiceClient(clientSecretCredential);

        var requestBody = new Microsoft.Graph.Models.List
        {
            DisplayName = "Ruklist",
            Columns = new List<ColumnDefinition>
            {
                new ColumnDefinition
                {
                    Name = "Author",
                    Text = new TextColumn { }
                },
                new ColumnDefinition
                {
                    Name = "PageCount",
                    Number = new NumberColumn { }
                }
            },
            
            ListProp = new ListInfo
            {
                Template = "genericList"
            }
        };

        try
        {
            // Replace with your actual Site ID
            var result = await graphClient.Sites["SiteID"].Lists.PostAsync(requestBody);
            Console.WriteLine("List created successfully: " + result.DisplayName);
        }
        catch (ODataError odataError)
        {
            Console.WriteLine($"OData Error Message: {odataError.Error.Message}");
            Console.WriteLine($"OData Error Code: {odataError.Error.Code}");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error creating list: " + ex.Message);
        }

    }
}

I am able to create the list successfully:
