загрузить большое видео в базу данных в asp.ngj

Я искал, как я могу сохранять и хранить видео большого размера, превышающего 4 МБ, в базу данных с помощью asp.net. Я пробовал много кодов. также я использовал:

<httpRuntime maxRequestLength="102400" executionTimeout="3600" />


<security >
  <requestFiltering>
    <requestLimits maxAllowedContentLength="1024000000" />
  </requestFiltering>
</security>

Это не работа. Он показывает мне сообщение:

время ожидания истекло. время ожидания истекло до завершения операции или сервер не отвечает

до сих пор я изменил столбец данных на varbinary (MAX), но я не могу хранить большой файл размером от 100 МБ до.

Мой код

    // Read the file and convert it to Byte Array
    string filePath = FileUpload1.PostedFile.FileName;
    string filename = Path.GetFileName(filePath);

    if (ext == ".jpg" || ext == ".gif" || ext == ".png" || ext == ".bmp " || ext == " .jpeg")
    {
        Stream fs = FileUpload1.PostedFile.InputStream;
        BinaryReader br = new BinaryReader(fs);
        Byte[] bytes = br.ReadBytes((Int32)fs.Length);

        //insert the file into database

        string strQuery = "insert into Image(Img_Title, Img_Extension, Img_Data, Course_code, Course_num, Img_Description, Keyword , Date)" +
