[英]Microsoft Graph API client library - create a folder
I'm trying to create a folder under an existing folder in SharePoint using Microsoft Graph (C# SDK). 我正在尝试使用Microsoft Graph(C#SDK)在SharePoint中的现有文件夹下创建一个文件夹。 I understand creating the folder on SharePoint or OneDrive should be the same when using the Graph API, but still, I couldn't find any good online references.
我知道使用Graph API时在SharePoint或OneDrive上创建文件夹应该是相同的,但是仍然找不到任何好的在线参考。 The only article I found is an old one , which only has an example in JavaScript.
我发现的唯一一篇文章是一篇旧文章,其中只有一个JavaScript示例。
I have a root folder A
and I want to create a subfolder B
under A
. 我有一个根文件夹
A
,我想在A
下创建一个子文件夹B
Here is the code: 这是代码:
var driveRequestBuilder = graphClient
.Sites[SharePointSiteId]
.Lists[ListId]
.Drive;
var folderRequestBuilder = driveRequestBuilder
.Root
.ItemWithPath("A");
var folderDriveItem = folderRequestBuilder
.Request()
.GetAsync()
.Result; // This returns the root folder "A"'s info
var subFolderDriveItem = new DriveItem()
{
Name = "B",
Folder = folderDriveItem.Folder
};
var result = folderRequestBuilder
.Request()
.CreateAsync(subFolderDriveItem)
.Result;
The last line of code throws an AggregateException
(because of TPL), which contains the inner exception: 代码的最后一行抛出一个
AggregateException
(由于TPL),其中包含内部异常:
Code: -1, Microsoft.SharePoint.Client.InvalidClientQueryException
Message: The parameter folder does not exist in method getByPath.
Inner error
I want to know the correct syntax to create the subfolder. 我想知道创建子文件夹的正确语法。
In case of sub folder the endpoint for creating a folder should be 如果是子文件夹,则用于创建文件夹的端点应为
POST https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/drive/root:/{path}:/children
Content-Type: application/json
{
"name": "New folder name",
"folder": { },
"@microsoft.graph.conflictBehavior": "rename"
}
Example for msgraph-sdk-dotnet
: msgraph-sdk-dotnet
示例:
var folder = new DriveItem
{
Name = "<sub folder name>",
Folder = new Folder()
};
var result = await graphClient
.Sites[siteId]
.Lists[listId]
.Drive
.Root
.ItemWithPath("<folder path>")
.Children
.Request()
.AddAsync(folder);
