将大型文件从android上传到c#WCF Rest服务

我正在开发一个android应用程序，我可以将视频、音频和图像从android设备上传到WCF REST服务。它完美地上传了一个10MB大小的视频文件，但当我试图上传一个1GB大小的视频文件时，它并没有上传到服务器。我想制作一个应用程序，在这个应用程序中，我可以将文件大小从3gb上传到4gb。我如何实现这一点？请任何人指导我实现这个方案

wcf服务代码：

public string PostImage(Stream stream)
        {
MultipartParser parser = new MultipartParser(stream);

            if (parser.Success)
            {
                string fileName = parser.Filename;
                string contentType = parser.ContentType;
                byte[] fileContent = parser.FileContents;
                FileStream fileToupload = new FileStream("D:\\FileUpload\\" + fileName, FileMode.Create);
                fileToupload.Write(fileContent, 0, fileContent.Length);
                fileToupload.Close();
                fileToupload.Dispose();
                stream.Close();
                return "Success !!!";
            }
            else
            {
                return "Exception!!!";
            }
        }

当我试图上传一个1GB的文件时，我得到的状态码是404

我需要进行更改，使我的代码上载到2gb到5gb的文件大小。有人能帮我解决这个问题吗。

您是否确保允许在iisSite->Request Filtering->Edit Feature Settingshow中进行大上传确保在IIS中进行大上传您能告诉我怎么做吗我编辑了功能设置，但无法上传1GB文件。如何将我的应用程序设置为无限制文件上载。要执行无限制上载，您应该一次发送文件块，而不是整个流。
