Question

我使用下面的代码使用Microsoft.SharePoint.Client将文件上传到SharePoint Online

上传文件后，会在库中创建新记录-如何获取该记录的ID？我想重新加载该记录以读取SharePoint中的计算字段（上传后计算得出）。

    FI = New IO.FileInfo(filename)

    Dim fileInformation As FileCreationInformation
    Dim item As ListItem
    Dim library As List = ctx.Web.Lists.GetByTitle(docLibrary)

    ctx.Load(library, Function(x) x.RootFolder.ServerRelativeUrl)
    ctx.ExecuteQuery()

    fileInformation = New FileCreationInformation
    With fileInformation
        .Url = library.RootFolder.ServerRelativeUrl & "/" & Filename
        .Overwrite = True
        .Content = System.IO.File.ReadAllBytes(newFilename)
    End With

    Dim fs As IO.FileStream = New IO.FileStream(newFilename, IO.FileMode.Open)
    Dim flciNewFile As FileCreationInformation = New FileCreationInformation()
    flciNewFile.ContentStream = fs
    flciNewFile.Url = System.IO.Path.GetFileName(newFilename)
    flciNewFile.Overwrite = True

    Dim docs As List = ctx.Web.Lists.GetByTitle(docLibrary)
    Dim uploadFile As Microsoft.SharePoint.Client.File = docs.RootFolder.Files.Add(flciNewFile)

    item = uploadFile.ListItemAllFields
    item("ColumnA") = "some metadata"
    item("ColumnB") = "some metadata"
    item.Update()

    ctx.Load(uploadFile)
    ctx.ExecuteQuery()

Answer 1

这是新上传的文件项的ID：

uploadFile.ListItemAllFields.Id

已更新：

请按如下所示在ClientContext中加载uploadFile.ListItemAllField：

item = uploadFile.ListItemAllFields
ctx.Load(item)
ctx.ExecuteQuery()

ListItem.Id property

Answer 2

这可以完成工作：

ctx.Load(uploadFile, Function(f) f.ListItemAllFields)
ctx.ExecuteQuery()
MsgBox(uploadFile.ListItemAllFields.Id)

检索上传文档的ID
