How to pass the byte array from flex to dotnet

In my project we need to save the image taken from webcam in a default path using flex 4.6 but giving a default path in flex(saving the image in a default path like C:\temp..) is not possible so we are passing the byte array of that captured image from flex to .ashx page in .net here,image is saving in a default path but imagebytes is not saving(showing that no data in image).If any body knows please let me know.

Finally i got the succeeded in passing the imagebytes from flex to ashx page like below

//Declare a string in script tag(Initialize a string before init() )
[Bindable]public var str64enc:String="";

//creating object for bytearray
[Bindable]public var imgbytes:ByteArray=new ByteArray(); 

//creating object for bitmapdata
[Bindable]public var picture1:BitmapData=new BitmapData(103,103,true);

**In your code**
var png:PNGEncoder=new PNGEncoder();
imgbytes=png.encode(picture1);

var base64enc:Base64Encoder=new Base64Encoder();
base64enc.encodeBytes(imgbytes);

str64enc=base64enc.toString();

STEP-BY-STEP PROCEDURE:-------

1-Take a base64encoder and encode the bytearray as below:

var base64enc:Base64Encoder=new Base64Encoder();
base64enc.encodeBytes(imgbytes);

2-then assign that base64 encoder object(In this case" base64enc") to string

3-In HTTPSERVICE u need to pass that string like:

<mx:HTTPService id="savepcktdata" method="POST"
    url="ur's destination path like..(axis/security/security.aspx)"
        result="savepcktdata_resultHandler(event)"                      
        resultFormat="text">
            <mx:request>
    <Operation>savepcktdata</Operation>     

    <bytes>
           {str64enc}
    </bytes>

    </mx:request>   
</mx:HTTPService>

4- In .aspx page u need to retrieve like:

string str = Convert.ToString(Request.Form["bytes"]);

cocnclusion:In order to pass the image bytes from flex(flash builder 4.6) to dotnet (visual studio) you need to pass through the base64 string like above code.
