我可以上传2GB或更大的文件到SharePoint Online吗?

我正在尝试编写一个c#应用程序，可以自动执行上传一个2gb的.zip文件到Office365 SharePoint Online网站。然而，我似乎不能得到任何方法，我试图工作。在多次无果而终的尝试之后，我开始使用"清单"。asmx"服务引用，它看起来很有希望，但是无论我如何配置，我总是得到异常。似乎应该有一个解决方案在那里，我怎么能上传一个单一的2gb .zip文件到SharePoint在线使用c# ?

对于凭证，我只是使用手动登录到SharePoint在线时使用的凭证。

下面的代码抛出一个由最后一个catch块捕获的异常，消息为:

SOAP header Security was not understand

如果我使用ListsSoapClient(b, ea)而不是无参数构造函数，则抛出一个不同的异常，由最后一个catch块捕获，声明:

内容类型(windows-1252)与绑定内容类型(utf-8)不匹配

另外，作为旁注:我假设ListsSoapClient()无参数构造函数使用我在App.config文件中指定的绑定?

Program.cs

string srcUrl = @"testingBACKUP.zip";
FileStream fStream = File.OpenRead(srcUrl);
string fileName = fStream.Name.Substring(3);
byte[] contents = new byte[fStream.Length];
fStream.Read(contents, 0, (int)fStream.Length);
fStream.Close();
EndpointAddress ea = new EndpointAddress("https://companyname.sharepoint.com/");
WSHttpBinding b = new WSHttpBinding();
b.Security.Mode = SecurityMode.TransportWithMessageCredential;
//b.Security.Message.ClientCredentialType = MessageCredentialType.Windows;
ListsSoapClient listService = new ListsSoapClient();//b, ea);
listService.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
listService.ClientCredentials.UserName.UserName = "<username>";
listService.ClientCredentials.UserName.Password = "<password>";
try
{
    var testing = listService.GetListContentType("Company", "windows-1252");
    string addAttach = listService.AddAttachment("Company", "1", fileName, contents);
}
catch (System.Web.Services.Protocols.SoapException ex)
{
    // catch error
}
catch (Exception e)
{
}
