无法使用图sdk在Sharepoint中在线创建新列表

Question

I have backed up the list from my site and deleted some list from it. Now I wanted to restore a List inside Site.

To restore list I used create List graph call(since the list was deleted) and passed all the data from the list that I backed up(excluding Name attribute).

The List that I passed as an argument is:

displayName : "qwerty"
list
columns
contentTypes
createdBy
createdDateTime : "2019-08-07T15:26:45+05:30"
description : ""
eTag : ""4aa6af8e-32d6-4ca9-ac0a-02c8e110f65d,6""
lastModifiedDateTime : "2019-08-07T15:26:45+05:30"
name : null
parentReference
webUrl : "https://dextorlab.sharepoint.com/sites/HelloWorld/Lists/qwerty"
id : "4aa6af8e-32d6-4ca9-ac0a-02c8e110f65d"
@odata.etag : ""4aa6af8e-32d6-4ca9-ac0a-02c8e110f65d,6

The Graph Call that is made is:

var ListResult = _SharepointOperations._GraphCLient.Sites[_SiteId].Lists.Request().AddAsync(siteList).Result;

I expect the output as successful, but graph return "one or more errors occurred" with inner error as "Unable to determine type of provided column definition"

You need format the siteList like below.

var siteList = 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"
    }
};

To add items to the list using this.

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var listItem = new ListItem
{
    Fields = new FieldValueSet
    {
        Title = "Widget",
        Color = "Purple",
        Weight = 32
    }
};

await graphClient.Sites["{site-id}"].Lists["{list-id}"].Items
    .Request()
    .AddAsync(listItem);
