IWMSCacheItemDescriptor.GetContentSize (C#)

The GetContentSize method retrieves the size of the content, in bytes.

Syntax

Parameters

plContentSizeLow

[out] int containing the low-order 8 bytes of the content size.

plContentSizeHigh

[out] int containing the high-order 8 bytes of the content size.

Return Values

This method does not return a value. To report an error, the plug-in can throw a COMException object to the server. If the plug-in uses the IWMSEventLog object to log error information, it is recommended that it throw NS_E_PLUGIN_ERROR_REPORTED (0xC00D157D). Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog object to send custom error information to the Windows Event Viewer, throwing NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about plug-in error information, see Identifying Plug-in Errors.

Remarks

The parameters are 32-bit signed long integers that represent the upper and lower 8 bytes of a 64-bit integer.

Example Code

using Microsoft.WindowsMediaServices.Interop;
using System.Runtime.InteropServices;

void IWMSCacheItemDescriptor.GetContentSize(out int sizeLow, out int sizeHigh)
{
  // The sizeLow and sizeHigh parameters are each 32 bits wide.
  sizeLow = sizeHigh = 0;
  try
  {
    sizeLow = // Determine the low-order bytes of the content size;
    sizeHigh = // Determine the high-order bytes of the content size.
  }
  catch(Exception e)
  {
    throw new COMException();
  }
}
