在OneDrive中上载文件时，对象引用未设置为对象

Question

我正在使用Microsoft Graph SDK在OneDrive中以块的形式上传文件。我使用下面的代码上传文件：

try
{
    GraphServiceClient graphClient = this.GetGraphServiceClient(accessToken);

    string fileName = Path.GetFileName(srcFilePath);

    using (var fileContentStream = System.IO.File.Open(srcFilePath, System.IO.FileMode.Open))
    {
        var uploadSession = await graphClient.Me.Drive.Root.ItemWithPath(fileName).CreateUploadSession().Request().PostAsync();

        var maxChunkSize = 5 * 1024 * 1024;
        var provider = new ChunkedUploadProvider(uploadSession, graphClient, fileContentStream, maxChunkSize);

        var chunkRequests = provider.GetUploadChunkRequests();
        var readBuffer = new byte[maxChunkSize];
        var trackedExceptions = new List<Exception>();
        Microsoft.Graph.DriveItem itemResult = null;

        foreach (var request in chunkRequests)
        {
            var result = await provider.GetChunkRequestResponseAsync(request, readBuffer, trackedExceptions);

            if (result.UploadSucceeded)
            {
                itemResult = result.ItemResponse;
            }
        }
    }
}
catch (Microsoft.Graph.ServiceException e)
{
}
catch (Exception ex)
{ 
}

以上代码适用于普通文件名。但是，当我尝试上传名称为 Test＃123.pdf 的文件时，＆＃34;对象引用未设置为对象＆＃34;行var provider = new ChunkedUploadProvider(uploadSession, graphClient, fileContentStream, maxChunkSize);引发异常请参见下面的屏幕截图：

这是OneDrive SDK的限制，还是我没有正确传递参数？

＃符号在URL中具有特殊含义。在您可以使用之前，您需要对文件名进行编码：Test%23123.pdf。
