在AX4.0中使用C#脚本的实现

1，虽然ms收购了ax,但是在ax低版本(ver<=4.0)中，还没有办法直接使用ms现在主推的.net技术。

通常的做法是现在AX中天津.net的引用，然后才能在代码中使用.net的一些对象以实现我们需要的功能。

2，添加引用

3. job中代码范本。

//test download image from web
//use this code can show web image on report print

   System.Net.HttpWebRequest     httpRequest    = null;
   System.Net.HttpWebResponse   httpResponse  = null;
   System.Net.CookieCollection     cookies           = null;

   CLRObject                            clro         = null;
   System.IO.Stream                stream;
   System.IO.StreamReader      reader;
   str                                 msg;
   BinData                         bidData=new BinData();
   Image       logoImage;
   Bitmap       Bitmap;
   System.Drawing.Image           webImage ;
   System.BitConverter            bit;
   ;
   new InteropPermission(InteropKind::ClrInterop).assert();
   clro         = System.Net.WebRequest::Create("http://www5.sml.com/**Online/images/img1.JPG");
   httpRequest  = clro;
   httpResponse = httpRequest.GetResponse();
   stream          = httpResponse.GetResponseStream();
   reader          = new System.IO.StreamReader(stream);
   webImage = System.Drawing.Image::FromStream(stream);//webImage.FromStream( httpResponse.GetResponseStream();
   webImage.Save("C:\\AXconfig\\001.jpg");
   bidData.loadFile("C:\\AXconfig\\001.jpg");
   Bitmap =  bidData.getData();

4, 实现.NET的另外一种方法，示例代码，实现通过AX系统上载文件到非windows服务器。所有的C#对象都声明为ClrObject.

static boolean SML_UpLoadFileByStream(Str url,Str FullFileName,Container conHeader=connull(),Container conQueryString=connull())
{
    ClrObject      PostArray;
    CLRObject      BinaryReader;
    CLRObject      WCHeaders,WCQueryString;
    ClrObject      FileStream;
    ClrObject      FileMode;
    ClrObject      FileAccess;
    ClrObject      PostStream;
    CLRObject      WC;
    System.Exception clrException;
    boolean        ret=false;
    int            i;
    Container      subcon;
    System.Net.WebClient xx;
    ;

    if (winapi::fileExists(FullFileName))
    {
        try
        {
            FileStream =  new CLRObject("System.IO.FileStream", FullFileName,
            CLRInterop::parseClrEnum("System.IO.FileMode","Open"), CLRInterop::parseClrEnum("System.IO.FileAccess", "Read"));
            BinaryReader =  new CLRObject("System.IO.BinaryReader", FileStream);
            PostArray= BinaryReader.ReadBytes(System.Convert::ToInt32(FileStream.get_Length()));
            WC = new CLRObject("System.Net.WebClient");
            if (conlen(conHeader))
            {
                WCHeaders=WC.get_Headers();
                for(i=1;i<=conlen(conHeader);i++)
                {
                   subcon=conpeek(conHeader,i);
                   WCHeaders.Add(conpeek(subcon,1),conpeek(subcon,2));
                }
            }
            if (conlen(conQueryString))
            {
                WCQueryString=WC.get_QueryString();
                for(i=1;i<=conlen(conQueryString);i++)
                {
                   subcon=conpeek(conQueryString,i);
                   WCQueryString.Add(conpeek(subcon,1),conpeek(subcon,2));
                }
            }
            PostStream=WC.OpenWrite(url, "POST");
            PostStream.Write(PostArray, 0,PostArray.get_Length());
            PostStream.close();
            FileStream.close();
        }
        catch(Exception::CLRError)
        {
            if (CLRInterop::isNull(PostStream) == false)
            {
               PostStream.Close();
            }
            if (CLRInterop::isNull(FileStream) == false)
            {
               FileStream.Close();
            }
        }
        ret=true;
    }
    return ret;
}
