如何从sharepoint网址下载文件 [英] how to download files from sharepoint url

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。

推荐答案

如果您知道文档库名称，则可以执行此操作。我有时会这样做。希望代码仍然有用:)如果不是这样尝试。

If you know the document library name, you can do it. I did this sometimes back. Hope the code still works :) If not just try along these lines.

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);
        }
    }
}

关于CopyStream：你真的不需要使用它，除非您使用的是.NET3.5或之前的版本。因为.NET3.5没有任何内置方法来复制流;所以我不得不使用一种方法来手动复制。正如我在上一篇回复中提到的那样;这是一段旧代码。但是.NET 4.0有

The files/dlls are located on any SharePoint 2013 server at %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\15\ISAPI or on any Sharepoint 2010 server at %ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\ISAPI. You can copy the dlls from the servers or else you can download them from http://www.microsoft.com/en-us/download/details.aspx?id=35585[^]

Regarding the CopyStream: You don't really need to use that unless you are using .NET3.5 or before. Because .NET3.5 didn't have any in-built method to copy the stream; so I had to use a method to manually copy. As I mentioned in my previous reply; It was an old piece of code. But .NET 4.0 has

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.
