我尝试使用以下dll将文件上传到OneDrive for Business/SharePoint:

Microsoft.Office。
Microsoft.Office365.SharePoint;
Microsoft.Office365.SharePoint.Extensions;

，代码如下:

public async void UploadDataAsync(byte[] bytes, string fileName)
{
    // NAME: TestFolder, ID: TestFolder, URL: /personal/[company]_onmicrosoft_com/Documents/TestFolder,                                                 SIZE: 0
    UserInformation userInformation = new UserInformation();
    userInformation.Id = "Castrovalva";
    userInformation.Name = "Castrovalva";
    Microsoft.Office365.SharePoint.File file = new Microsoft.Office365.SharePoint.File();
    file.CreatedBy = userInformation;
    file.LastModifiedBy = userInformation;
    file.Id = fileName;
    file.Name = fileName;
    file.Url = "/personal/[company]_onmicrosoft_com/Documents/TestFolder";
    file.TimeCreated = DateTime.Now;
    file.TimeLastModified = DateTime.Now;
    file.ETag = "ETAG";
    using (MemoryStream memory = new MemoryStream(bytes))
    {
        await file.UploadAsync(memory);
    }
}

当我尝试运行这段代码时，我得到了这个错误:

系统。异常:{"cannot find entity"}
来源:Microsoft.Office365。SharePoint

我不明白的是，我不需要SharePointClient(客户端连接到sharepoint)对象来执行代码。
因为当我想要获取所有文件的信息或者需要连接时，我会使用这个对象。

_client = await EnsureClientCreated();
_client.Context.IgnoreMissingProperties = true;

那么我如何上传文件到OneDrive for Business/SharePoint?

我找到了一个解决方案，它比我想象的要简单得多:

using (Stream stream = new MemoryStream(bytes))
{
    try
    {
        //await _client.Context.ExecuteAsync(uri, "POST", stream);
        await _client.Files.AddAsync(fileName, true, stream);
    }
    catch (InvalidOperationException exception)
    { MessageBox.Show(exception.Message); }
}
