Lists

GraphQL allows us to return lists of elements from our fields.

SDL

type Query {
  users: [User]
}

Clients can query list fields like any other field.

GraphQL

{
  users {
    id
    name
  }
}

Querying a list field will result in an ordered list containing elements with the specified sub-selection of fields.

Usage

Lists can be defined like the following.

If our field resolver returns a list type, e.g. IEnumerable<T> or IQueryable<T>, it will automatically be treated as a list type in the schema.

public class Query
{
    public List<User> GetUsers()
    {
        // Omitted code for brevity
    }
}


If our field resolver returns a list type, e.g. IEnumerable<T> or IQueryable<T>, it will automatically be treated as a list type in the schema.
C#
public class QueryType : ObjectType
{
    protected override void Configure(IObjectTypeDescriptor descriptor)
    {
        descriptor.Name(OperationTypeNames.Query);

        descriptor
            .Field("users")
            .Resolve(context =>
            {
                List<User> users = null;

                // Omitted code for brevity

                return users;
            });
    }
}


We can also be more explicit by specifying a ListType<Type> as the return type.
C#
public class QueryType : ObjectType
{
    protected override void Configure(IObjectTypeDescriptor descriptor)
    {
        descriptor.Name(OperationTypeNames.Query);

        descriptor
            .Field("users")
            .Type<ListType<UserType>>()
            .Resolve(context =>
            {
                // Omitted code for brevity
            });
    }
}
