如何将大数据从客户端传输到服务器

我在客户端使用以下代码将数据从客户端传输到服务器。

FileStream fs = new FileStream(FilePath + dsBlockImages.Tables[0].Rows[i]["ImageName"].ToString(), FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
eventLog1.WriteEntry(buffer.Length.ToString());
using (MemoryStream ms = new MemoryStream(buffer))
{
    proxy.GetAllModuleDocumentsForServerSyncUp(buffer, dsBlockImages.Tables[0].Rows[i]["ImageName"].ToString(), fileindication);
}

在服务器中，我在WCF服务 中编写了以下代码

if (!File.Exists(System.Web.Hosting.HostingEnvironment.MapPath(filetargetpath) + FileName))
{
    FileStream writeStream = new FileStream(System.Web.Hosting.HostingEnvironment.MapPath(filetargetpath) + FileName, FileMode.Append, FileAccess.Write);
    writeStream.Write(buffer, 0, buffer.Length);
    writeStream.Close();
}

这是为小文件工作，如果我发送大文件，它是错误的请求。我已经指定了网页的大小限制。配置也，但它给出相同的异常
