请参阅下面的代码了解更多详细信息，我感谢您帮助解决当前基于 URL 面临的问题。错误 - 找不到该段的资源 好的。

public static string DecodeData(string encodedData)
{
    byte[] encodedDataAsBytes = System.Convert.FromBase64String(encodedData);
    string returnValue = System.Text.ASCIIEncoding.ASCII.GetString(encodedDataAsBytes);
    return returnValue;
}
// Upload files to SharePoint
public void SharePointUploadDriveItems(string accessToken)
{
    var httpClient = new HttpClient();

    try
    {
        string path = @"C:\\StockLevelReportLocation\\New Files\\TestFileUpload.xlsx";
        byte[] filebytes = System.IO.File.ReadAllBytes(path);

        using (var client = new HttpClient())
        {
            string fileName = "TestFileToUpload.txt";

            using (var request = new HttpRequestMessage(HttpMethod.Put, "https://graph.microsoft.com/v1.0/drives/root/Oks/Stock Report/TestFileUpload.xlsx/content"))
            {
                request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
                request.Headers.Add("Accept", "application/json;odata.metadata=verbose");
                request.Content = new StringContent(DecodeData(Convert.ToBase64String(filebytes)), System.Text.Encoding.ASCII, "text/plain");
                var driveItemsResponse = httpClient.SendAsync(request).Result;
                var driveItemsResponseContent = driveItemsResponse.Content.ReadAsStringAsync().Result;
            }
        }
    }
    catch (Exception ex)
    {
        throw new Exception(ex.ToString());
    }
}

看起来您在 URL 路径的开头和结尾处缺少

:

。另一个问题是您没有指定驱动器 ID

您的网址

https://graph.microsoft.com/v1.0/drives/root/Oks/Stock Report/TestFileUpload.xlsx/content

但应该是

https://graph.microsoft.com/v1.0/drives/{drive_id}/root:/Oks/Stock Report/TestFileUpload.xlsx:/content

代码

using (var request = new HttpRequestMessage(HttpMethod.Put, "https://graph.microsoft.com/v1.0/drives/{drive_id}/root:/Oks/Stock Report/TestFileUpload.xlsx:/content"))
{
    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
    request.Headers.Add("Accept", "application/json;odata.metadata=verbose");
    request.Content = new StringContent(DecodeData(Convert.ToBase64String(filebytes)), System.Text.Encoding.ASCII, "text/plain");
    var driveItemsResponse = httpClient.SendAsync(request).Result;
    var driveItemsResponseContent = driveItemsResponse.Content.ReadAsStringAsync().Result;
}
