我有一個(gè) Web 表單，可以將一些輸入的數(shù)據(jù)作為一個(gè)新的列表項(xiàng)上傳到 SharePoint 列表，效果很好。我試圖添加一個(gè)新代碼來(lái)通過兩個(gè)單獨(dú)的<asp:FileUpload>控件上傳兩個(gè)文件。以下代碼protected void sendToSharePoint() {}無(wú)法將任何一個(gè)文件上傳到指定的 SharePoint 文檔庫(kù)，更不用說(shuō)兩者了：默認(rèn).aspx：//Existing code<asp:FileUpload ID="upldGradeReport" runat="server" /><asp:FileUpload ID="upldExpenseReceipt" runat="server" /><asp:Button ID="btnSubmitForm" OnClick="SubmitButton_Click" runat="server" Text="Submit" />默認(rèn).aspx.cs：using System;using System.DirectoryServices;using System.IO;using System.Security;using System.Web.UI;using Microsoft.SharePoint.Client;using ClientOM = Microsoft.SharePoint.Client;//I left out the NameSpace and default public partial class wrapper, but they're here.public ClientContext SPClientContext { get; set; }public string SPErrorMsg { get; set; }protected void SubmitButton_Click(object sender, EventArgs e) {    sendToSharePoint();    Response.BufferOutput = true;    Response.Redirect("Submission.aspx");}protected void sendToSharePoint() {    try {        string siteUrl = "<sharepoint site url>";        ClientContext clientContext = new ClientContext(siteUrl);        clientContext.Credentials = new SharePointOnlineCredentials("<my username>", "<my password>");        string sDocName = string.Empty;        string sDocName1 = string.Empty;        Uri uri = new Uri(siteUrl);        string sSPSiteRelativeURL = uri.AbsolutePath;        sDocName = UploadFile(upldGradeReport.FileContent, upldGradeReport.FileName, sSPSiteRelativeURL, "<sharepoint document library>");        sDocName1 = UploadFile(upldExpenseReceipt.FileContent, upldExpenseReceipt.FileName, sSPSiteRelativeURL, "<sharepoint document library>");        //prior CSOM code to insert values into a new List Item exists here        clientContext.ExecuteQuery();    } catch (Exception ex) {        String ThisError = ex.Message;    }}創(chuàng)建新 ListItem 并將表單的其余輸入數(shù)據(jù)上傳到單獨(dú)的 SharePoint 列表的代碼在提交時(shí)仍然有效，我已經(jīng)確認(rèn)憑據(jù)正確并且正在使用的帳戶有權(quán)將文件上傳到文檔圖書館。我究竟做錯(cuò)了什么？
