试试这个代码

 byte[] buffer;
//this is the array of bytes which will hold the data (file)

SqlConnection connection;
protected void ButtonUpload_Click(object sender, EventArgs e)
{
    //check the file

    if (FileUpload1.HasFile && FileUpload1.PostedFile != null 
        && FileUpload1.PostedFile.FileName != "")
    {
        HttpPostedFile file = FileUpload1.PostedFile;
        //retrieve the HttpPostedFile object

        buffer = new byte[file.ContentLength];
        int bytesReaded = file.InputStream.Read(buffer, 0, 
                          FileUpload1.PostedFile.ContentLength);

        if (bytesReaded > 0)
        {
            try
            {
                string connectionString = 
                  ConfigurationManager.ConnectionStrings[
                  "uploadConnectionString"].ConnectionString;
                connection = new SqlConnection(connectionString);
                SqlCommand cmd = new SqlCommand
                ("INSERT INTO Videos (Video, Video_Name, Video_Size)" + 
                 " VALUES (@video, @videoName, @videoSize)", connection);
                cmd.Parameters.Add("@video", 
                    SqlDbType.VarBinary, buffer.Length).Value = buffer;
                cmd.Parameters.Add("@videoName", 
                    SqlDbType.NVarChar).Value = FileUpload1.FileName;
                cmd.Parameters.Add("@videoSize", 
                    SqlDbType.BigInt).Value = file.ContentLength;
                using (connection)
                {
                    connection.Open();
                    int i = cmd.ExecuteNonQuery();
                    Label1.Text = "uploaded, " + i.ToString() + " rows affected";
                }
            }
            catch (Exception ex)
            {
                Label1.Text = ex.Message.ToString();
            }
        }

    }
    else
    {
        Label1.Text = "Choose a valid video file";
    }
}
