从客户端对象模型将文档上传到 SharePoint 列表 [英] Upload a document to a SharePoint list from Client Side Object Model

问题描述

I need to upload a document to a SharePoint list or folder using the Client Side Object Model from .NET (C#). What is the best way to do this?

The requirements are as follows:

• Set metadata values

• No limitation on file size

• Must work with libraries that exceed the List View Threshold

解决方案

For Uploading Document to Sharepoint Document Library use Following function in Client Object Model:

public void UploadDocument(string siteURL, string documentListName, string documentListURL, string documentName, byte[] documentStream)
{
    using (ClientContext clientContext = new ClientContext(siteURL))
    {
        //Get Document List
        List documentsList = clientContext.Web.Lists.GetByTitle(documentListName);

        var fileCreationInformation = new FileCreationInformation();
        //Assign to content byte[] i.e. documentStream

        fileCreationInformation.Content = documentStream;
        //Allow owerwrite of document

        fileCreationInformation.Overwrite = true;
        //Upload URL

        fileCreationInformation.Url = siteURL + documentListURL + documentName;
        Microsoft.SharePoint.Client.File uploadFile = documentsList.RootFolder.Files.Add(
            fileCreationInformation);

        //Update the metadata for a field having name "DocType"
        uploadFile.ListItemAllFields["DocType"] = "Favourites";

        uploadFile.ListItemAllFields.Update();
        clientContext.ExecuteQuery();
    }
}
