我可以将 2GB 或更大的文件上传到 SharePoint Online 吗？

Question

我正在尝试编写一个可以自动执行以将 2 GB .zip 文件上传到 Office365 SharePoint Online 站点的 C# 应用程序。但是，我似乎无法获得任何尝试工作的方法。经过多次无果而终的尝试后，我一直在深入研究使用 "Lists.asmx" 服务参考，这看起来很有希望，但无论我如何配置，我都会不断收到异常。似乎应该有一个解决方案，如何使用 C# 将单个 2 GB .zip 文件上传到 SharePoint Online？

对于凭据，我一直在使用我用来手动登录 SharePoint online 的凭据。

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 understood

如果我使用 ListsSoapClient(b, ea) 而不是无参数构造函数，则最后一个 catch 块会抛出一个不同的异常：

the content type (windows-1252) does not match the binding content type (utf-8)

此外，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)
{
}

我认为您无法将大文件上传到 SharePoint Online。 SharePoint Online 的限制是最大文件 2GB。
