推荐答案

您需要做的就是添加文件上传控件 [ ^ ]到您的页面，并检查代码中的HasFile属性。

如果为true，则将文件保存到磁盘或数据库为必要的（但是我将视频保存到磁盘，这对于数据库来说是个大问题）

All you need to do is add an FileUpload Control[^] to your page, and check the HasFile property in your code.
If true, you save the file to disk or to a DB as necessary (but I'd save video to disk, it's a big big for a DB)

/// <summary>
/// Save an upload into the database.
/// </summary>
/// <param name="fl">Control containing the download.</param>
/// <returns>Status as a string</returns>
private string SaveUpload(FileUpload fl)
    {
    if (fl.HasFile)
        {
        try
            {
            int version = 0;
            string filename = Path.GetFileName(fl.FileName);
            byte[] filedata = fl.FileBytes;
            string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["DownloadDatabase"].ConnectionString;
            using (SqlConnection con = new SqlConnection(strCon))
                {
                con.Open();
                // Check version - if the file exists in the DB already, then increase version number.
                using (SqlCommand ver = new SqlCommand("SELECT MAX(version) FROM dlContent WHERE fileName=@FN", con))
                    {
                    ver.Parameters.AddWithValue("@FN", filename);
                    object o = ver.ExecuteScalar();
                    if (o != null && o != System.DBNull.Value)
                        {
                        // Exists already.
                        version = (int) o + 1;
                        }
                    }
                // Stick file into database.
                using (SqlCommand ins = new SqlCommand("INSERT INTO dlContent (iD, fileName, description, dataContent, version, uploadedOn) " +
                                                       "VALUES (@ID, @FN, @DS, @DT, @VS, @UD)", con))
                    {
                    ins.Parameters.AddWithValue("@ID", Guid.NewGuid());
                    ins.Parameters.AddWithValue("@FN", filename);
                    ins.Parameters.AddWithValue("@DS", "");
                    ins.Parameters.AddWithValue("@DT", filedata);
                    ins.Parameters.AddWithValue("@VS", version);
                    ins.Parameters.AddWithValue("@UD", DateTime.Now);
                    ins.ExecuteNonQuery();
                    }
                }
            return string.Format("{0} uploaded, version = {1}", filename, version);
            }
        catch (Exception ex)
            {
            return "The file could not be uploaded. The following error occured: " + ex.Message;
            }
        }
    return "Please select a file.";
    }
