AX 2009 文件读写

AX 文件内容的读写

X++ 这方面使用的是.net Framework，读取文件时，要权限放行。

以下代码，会看到可爱的System.IO.SteamReader。如此熟悉，感动ing。。。

 

static void readJob(Args _args)
{
    System.IO.StreamReader m_streader;
    InteropPermission m_Perm = new InteropPermission(InteropKind::ClrInterop);
    Notes      m_Notes;

    m_Perm.assert();

    m_streader = new System.IO.StreamReader(@"C:\ms\n01yan_100.copy");

    while(int642int(m_streader.Peek())>0)
    {
        m_Notes += m_streader.ReadToEnd();
    }

    m_streader.Close();
    m_streader.Dispose();

    CodeAccessPermission::revertAssert();

    info(m_Notes);

//   pause;
}

 

 写入

 

static void StreamWriter(Args _args)
{
    System.IO.StreamWriter sw;
    InteropPermission perm = new InteropPermission(InteropKind::ClrInterop);
    SalesTable   st;
    ;

    perm.assert();

    sw = new System.IO.StreamWriter(@"C:\test.txt");
    while select st
    {
       sw.WriteLine(st.SalesId);
       sw.WriteLine(st.CustAccount + "    " + Date2str(st.DeliveryDate,321,2,3,2,3,4));

    }

    sw.Flush();
    sw.Close();
    sw.Dispose();

    CodeAccessPermission::revertAssert();}
