图API：修改目录内文件内容

Question

我正在尝试使用 .NET 将文件上传到某个 SharePoint 目录。到目前为止，我可以将它上传到根目录：

var fileItem = new DriveItem
{
    Name = "test3.txt",
    File = new Microsoft.Graph.File
            {
            },
    AdditionalData = new Dictionary<string, object>()
            {
                {"@microsoft.graph.conflictBehavior", "rename"}
            }
};

await graphClient
    .Sites["*****.sharepoint.com"]
    .Drive
    .Root
    .Children
    .Request()
    .AddAsync(fileItem);

var sites = await graphClient
    .Sites["*****.sharepoint.com"]
    .Drive
    .Root
    .Children["test3.txt"].Content.Request().PutAsync<DriveItem>(stream);

我可以在文件夹中创建文件：

await graphClient
    .Sites["*****.sharepoint.com"]
    .Drive
    .Root.Children["New Folder3"]
    .Children
    .Request()
    .AddAsync(fileItem);

但是当我尝试向该文件（目录内）添加内容时：

await graphClient
        .Sites["*****.sharepoint.com"]
        .Drive
        .Root
        .Children["New Folder3"]
        .Children["test.txt"].Content.Request().PutAsync<DriveItem>(stream);

我捕捉到了 ResourceNotFoundException 异常。

您可以尝试使用'ItemWithPath'方法并按照 or it would be better giving the id rather than using the Folder name or file name and use it according to this document中所述指定路径。
