But nothing is working. So I need a little help. Here is code that I have tried:
但没有任何效果。所以我需要一点帮助。这是我尝试过的代码：

1：（我也试过用SharePointOnlineCredentials代替NetworkCredential这个）
#region 403 forbidden
byte[] content = System.IO.File.ReadAllBytes(fileInfo.FullName);
System.Net.WebClient webclient = new System.Net.WebClient();
System.Uri uri = new Uri(sharePointSite + directory + fileInfo.Name);
webclient.Credentials = new NetworkCredential(user, password.ToString(), sharePointSite + "Documents");
webclient.UploadData(uri, "PUT", content);

#region 500 Internal Server Error
using (var fs = new FileStream(fileInfo.FullName, FileMode.Open))
{
Microsoft.SharePoint.Client.File.SaveBinaryDirect(
context,
web.ServerRelativeUrl + "/" + directory,
fs,
true);
}
#endregion
I have gotten smaller file uploads to work with:
我已经上传了较小的文件来处理：
#region File upload for smaller files
Folder folder = context.Web.GetFolderByServerRelativeUrl(web.ServerRelativeUrl + directory);
web.Context.Load(folder);
context.ExecuteQuery();
FileCreationInformation fci = new FileCreationInformation();
fci.Content = System.IO.File.ReadAllBytes(fileInfo.FullName);
fciURL = sharePointSite + directory;
fciURL += (fciURL[fciURL.Length - 1] == '/') ? fileInfo.Name : "/" + fileInfo.Name;
fci.Url = fciURL;
fci.Overwrite = true;
Microsoft.SharePoint.Client.FileCollection documentfiles = folder.Files;
context.Load(documentfiles);
context.ExecuteQuery();
Microsoft.SharePoint.Client.File file = documentfiles.Add(fci);
context.Load(file);
context.ExecuteQuery();
#endregion
My Using Statement:
我的使用声明：
using (Microsoft.SharePoint.Client.ClientContext context = new Microsoft.SharePoint.Client.ClientContext(sharePointSite))
{
//string fciURL = "";
exception = "";
context.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials(user, password);
Web web = context.Web;
web.Context.Credentials = context.Credentials;
if (!web.IsPropertyAvailable("ServerRelativeUrl"))
{
web.Context.Load(web, w => w.ServerRelativeUrl);
web.Context.ExecuteQuery();
}
//upload large file
}

The solution I went with:
我采用的解决方案：
MemoryStream destStream;
using (System.IO.FileStream fInfo = new FileStream(fileInfo.FullName, FileMode.Open))
{
byte[] buffer = new byte[16 * 1024];
byte[] byteArr;
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = fInfo.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
byteArr = ms.ToArray();
}
destStream = new MemoryStream(byteArr);
Microsoft.SharePoint.Client.File.SaveBinaryDirect(
context,
serverRelativeURL + directory + fileInfo.Name,
destStream,
true);
context.ExecuteQuery();
results = "File Uploaded";
return true;
}

The problem with your code snippet number 2 is that you missed a file name:
您的代码片段编号 2 的问题是您错过了一个文件名：
using (var fs = new FileStream(fileInfo.FullName, FileMode.Open))
{
Microsoft.SharePoint.Client.File.SaveBinaryDirect(
context,
serverRelativeURL + directory + fs.Name,
^^^^^^^^
fs,
true);
}

My research on the subject showed that using the FrontPage Remote Control Procedureswas the most adventageous way of reliably uploading large files.
我对这个主题的研究表明，使用FrontPage 远程控制程序是可靠上传大文件的最有利的方式。
This is because FrontPage RPC supports file fragmentation, which helps avoid OutOfMemomoryexceptions due to Windows needing to allocate the entire file to continuous memory.
这是因为 FrontPage RPC 支持文件碎片化，这有助于避免OutOfMemomory由于 Windows 需要将整个文件分配到连续内存而导致的异常。
It also supports sending meta data, useful it pretty much any file upload application. One major advantage of this is that you can actually specify the correct content type without a user having to log in and change it later. (with all other methods I tried it would just be set as the default type.)
它还支持发送元数据，几乎可以用于任何文件上传应用程序。这样做的一个主要优点是您实际上可以指定正确的内容类型，而无需用户稍后登录和更改。（对于我尝试过的所有其他方法，它只会被设置为默认类型。）
See my answer on the Sharepoint StackExchangefor further detail on implementing Frontpage RPC.
