FilePathResult使用大文件抛出OutOfMemoryException

我在我的控制器中有这个Action,它将一个文件返回给用户.

public virtual ActionResult ReturnFile(string fileName, string filePath, string contentType)
{
    var cd = new System.Net.Mime.ContentDisposition
    {
        FileName = fileName,

        // always prompt the user for downloading, set to true if you want 
        // the browser to try to show the file inline
        Inline = false,
    };

    // set token for close the modal-window
    CookiesHelper.SetValueDownloadTokenInCookie();
    Response.AppendHeader("Content-Disposition", cd.ToString());
    return File(filePath, contentType);
}

它工作正常,但问题是,当文件很大(略大于220 Mb)时,它会抛出一个OutOfMemoryException.

这是堆栈跟踪

[OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.]
   System.IO.MemoryStream.set_Capacity(Int32 value) +93
   System.IO.MemoryStream.EnsureCapacity(Int32 value) +64
   System.IO.MemoryStream.Write(Byte[] buffer, Int32 offset, Int32 count) +330

   System.Web.CallFilterExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +49
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +69

有任何想法吗？
