如何从sharepoint网址下载文件

问题描述

早安朋友。



我想从共享点下载文件URL。但我无法下载。

i找到了代码，但所有代码只下载了一个文件。

但我想下载SharePoint门户网站链接中的所有文件。 />
在该链接上我有一个列，例如，



文件名已发布日期





这里可能会发布10到15个文件我想在运行程序时下载我本地文件夹中的所有文件。



并且名称格式将相同，只有日期可以在发布日期列中更改。



i想要循环浏览所有文件，以便我们可以逐个下载所有文件。



请帮我急。



先谢谢。

推荐答案

using SPC = Microsoft.SharePoint.Client;

using (SPC.ClientContext context = new SPC.ClientContext(siteUrl))
{
    context.Credentials = new NetworkCredential("username", "password");
    SPC.Web myWeb = context.Web;
    context.Load(myWeb, website => website.Title);
    context.ExecuteQuery();

    //Load Sample Documents document library
    SPC.List documentsList = myWeb.Lists.GetByTitle("Sample Documents");
    context.Load(documentsList);
    context.ExecuteQuery();

    //Load documents in the document library
    SPC.ListItemCollection listItemCollection = documentsList.GetItems(new SPC.CamlQuery());
    context.Load(listItemCollection);
    context.ExecuteQuery();

    foreach (SPC.ListItem item in listItemCollection)
    {
        SPC.FileInformation fileInfo = SPC.File.OpenBinaryDirect(context, item["FileRef"].ToString());

        using (MemoryStream memoryStream = new MemoryStream())
        {
            CopyStream(fileInfo.Stream, memoryStream);
            //Retrieved file is saved as byte array
            Byte[] retrievedFile= memoryStream.ToArray();

            string outFileName = @"C:\temp\test\" + item["FileLeafRef"].ToString();

            //Write the file to disk
            File.WriteAllBytes(outFileName, retrievedFile);
        }
    }
}

Stream.CopyTo

而.NET 4.5有

Stream.CopyToAsync

所以你可以使用其中任何一个将流复制到另一个。

So you can use either one of them to copy the stream to another.
