无法使用 CSOM 将文件上传到文档库

Question

我正在尝试将多个文件上传到文档库并更新其列值。 List(Doc Lib) 已经存在，但我坚持上传文件

这些方法我都试过了

使用lists.asmx

        NetworkCredential credentials = new NetworkCredential("user", "Pass", "domain");
        #region ListWebService
        ListService.Lists listService = new ListService.Lists();
        listService.Credentials = credentials;
        List list = cc.Web.Lists.GetByTitle(library);
        listService.Url = cc.Url + "/_vti_bin/lists.asmx";
        try
        {
            FileStream fStream = System.IO.File.OpenRead(filePath);
            string fName = fStream.Name.Substring(3);
            byte[] contents = new byte[fStream.Length];
            fStream.Read(contents, 0, (int)fStream.Length);
            fStream.Close();

            string attach = listService.AddAttachment(library, itemId.ToString(), Path.GetFileName(filePath), contents);

        }
        #endregion


        catch (System.Web.Services.Protocols.SoapException ex)
        {
            CSVWriter("Message:\n" + ex.Message + "\nDetail:\n" +
                ex.Detail.InnerText + "\nStackTrace:\n" + ex.StackTrace, LogReport);
        }

它在 AddAttachment()

上给出错误 ServerException :To add an item to a document library, use SPFileCollection.Add()

使用

        List lib = cc.Web.Lists.GetByTitle("TestLib");
         FileCreationInformation fileInfo = new FileCreationInformation();
         fileInfo.Content = System.IO.File.ReadAllBytes("C:\Users\AJohn\Desktop\sample.docx");
         fileInfo.Url = "https://serverm/sites/Testing1/TestLib/sample.docx";
         fileInfo.Overwrite = true;
         Microsoft.SharePoint.Client.File upFile = lib.RootFolder.Files.Add(fileInfo);
         cc.Load(upFile);
         cc.ExecuteQuery();

我能够使用此方法上传 once，但现在我在 cc.ExecuteQuery()

上上传 ServerException :To add an item to a document library, use SPFileCollection.Add()

但是如果这个方法真的有效，我想要的是我应该更新与这个文件相关的列值。在第一种方法中，我得到 item.ID 所以我可以从那里更新 Coloumn Values

Answer 1

关于第二种方法，以下示例演示如何将文件上传到文档库并设置其属性（例如Category文本字段）

using (var ctx = new ClientContext(webUri))
{
     var targetList = ctx.Web.Lists.GetByTitle("Documents");
     var fileInfo = new FileCreationInformation
     {
          Url = System.IO.Path.GetFileName(sourcePath),
          Content = System.IO.File.ReadAllBytes(sourcePath),
          Overwrite = true
     };

     var file = targetList.RootFolder.Files.Add(fileInfo);
     var item = file.ListItemAllFields;
     item["Category"] = "User Guide";
     item.Update();
     ctx.ExecuteQuery();
}

无法使用 CSOM 将文件上传到文档库
