Namespace:  System.Drawing.Imaging
Assembly:  System.Drawing (in System.Drawing.dll)
public void PlayRecord(
	EmfPlusRecordType recordType,
	int flags,
	int dataSize,
	byte[] data
)

Parameters

recordType
Type: System.Drawing.Imaging.EmfPlusRecordType

Element of the EmfPlusRecordType that specifies the type of metafile record being played.

flags
Type: System.Int32

A set of flags that specify attributes of the record.

dataSize
Type: System.Int32

The number of bytes in the record data.

data
Type: System.Byte[]

An array of bytes that contains the record data.

The following code example demonstrates how to use the PlayRecord method.

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Windows.Forms;

// for Marshal.Copy 
using System.Runtime.InteropServices; 

public class Form1 : Form
{
    private Metafile metafile1;
    private Graphics.EnumerateMetafileProc metafileDelegate;
    private Point destPoint;
    public Form1()
    {
        metafile1 = new Metafile(@"C:\Test.wmf");
        metafileDelegate = new Graphics.EnumerateMetafileProc(MetafileCallback);
        destPoint = new Point(20, 10);
    }
    protected override void OnPaint(PaintEventArgs e)
    {
        e.Graphics.EnumerateMetafile(metafile1, destPoint, metafileDelegate);
    }
    private bool MetafileCallback(
       EmfPlusRecordType recordType,
       int flags,
       int dataSize,
       IntPtr data,
       PlayRecordCallback callbackData)
    {
        byte[] dataArray = null;
        if (data != IntPtr.Zero)
        {
            // Copy the unmanaged record to a managed byte buffer  
            // that can be used by PlayRecord.
            dataArray = new byte[dataSize];
            Marshal.Copy(data, dataArray, 0, dataSize);
        }

        metafile1.PlayRecord(recordType, flags, dataSize, dataArray);

        return true;
    }

    static void Main()
    {
        Application.Run(new Form1());
    }
}
