                                    <param name="movie" value="<% =swfFileName%>" />
                                    <param name="quality" value="high" />
                                    <embed src="<% =swfFileName%>" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer"
                                        type="application/x-shockwave-flash" width="200" height="100"></embed>
                                </object>
                            </td>
                        </tr>
                    </table>
                </td>
            </tr>
        </table>
    </form>

// Now Add a namespace System.IO; to the PlaySwfFile.aspx.cs file

// Declare a variable above page_load() method

  public string swfFileName = "";

 // Now double click on the upload button and ddd the following code below

protected void btnUpload_Click(object sender, EventArgs e)
     {
        if (fUpload.FileContent.Length >0 && IsVaildFile())
        {
            string Path = GetUplaodImagePhysicalPath();
            DirectoryInfo dirUploadImage = new DirectoryInfo(Path);
            if (dirUploadImage.Exists == false)
            {
                dirUploadImage.Create();
            }
            string fileUrl = Path + fUpload.PostedFile.FileName;
            fUpload.PostedFile.SaveAs(fileUrl);
            swfFileName = "image/" + fUpload.PostedFile.FileName;
        }
    }
    private bool IsVaildFile()
    {
        string swfExt = System.IO.Path.GetExtension(fUpload.PostedFile.FileName);
        switch (swfExt)
        {
            case ".swf":
                return true;
            default:
            {
                    lblMsg.Text = "Please select only swf file.";
                    return false;
            }
        }
    }


    
    string GetUplaodImagePhysicalPath()
    {
        return System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "image\\";
    }
  
}

Now run the project and upoad a swf file and click on upload button. you will get the result.

Points to Remember

In the .cs page you will get a public variable named swfFileName. This is the variable which is used in the aspx page to assign as the source of <object>.

Here <object> serves as swf player.

In aspx file the public variable swfFileName is accessed as <% =swfFileName%>
