问题描述

在将电子邮件附件读取为.msg或.eml扩展名时遇到问题，它无法保存在磁盘上，或者在调试模式下在附件[]中显示时也显示null.您能帮助/解决问题还是建议替代方案?

Hi,

I''m facing problem while reading email attachment as .msg or .eml extension, it does not save on disk or also show null while seeing in attachment[] in debug mode. can you please help/resolve the issue or advise alternate.

    private void GetAttachNames( out MailAttach[] aat )
{
aat = new MailAttach[ lastMsg.fileCount ];
Type fdtype = typeof(MapiFileDesc);
int fdsize = Marshal.SizeOf( fdtype );
MapiFileDesc fdtmp = new MapiFileDesc();
int runptr = (int) lastMsg.files;
for( int i = 0; i < lastMsg.fileCount; i++ )
    {
    Marshal.PtrToStructure( (IntPtr) runptr, fdtmp );
    runptr += fdsize;
    aat[i] = new MailAttach();
    if( fdtmp.flags == 0 )
        {
        aat[i].position = fdtmp.position;
        aat[i].name     = fdtmp.name;
        aat[i].path     = fdtmp.path;
        }
    }
