In C# you would use this code to populate a ByteArray from a String:

string postData = "xml content";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);

How to do it in X++?

Thanks, Jan

Hi

After playing around with ClrInterop what did not work we used .NET classes and made a reference in AOT.

The very direct approach is to do the same in AX (2009):

str postData = "xml content";
System.Byte[] byteArray;
System.Text.Encoding encodingUTF8;
;

encodingUTF8 = System.Text.Encoding::get_UTF8();
byteArray = encodingUTF8.GetBytes(postData);

It depends on what for the array of bytes is required.

Of course you can it direct, until you have to go back to AX datatype, than you have to use CLRInterop for conversion. There is the point where not all types can be handeld in AX.

System.Byte can be implicitly converted to X++ int. You can call GetBytes, iterate over the array and convert the items to int:

str                     postData = "xml content";

System.Byte[]                     byteArray;

System.Text.Encoding    encodingUTF8;

int byte, i, arrayLength;

;

encodingUTF8 = System.Text.Encoding::get_UTF8();

byteArray = encodingUTF8.GetBytes(postData);

arrayLength = byteArray.get_Length();



for (i = 0; i < arrayLength; i++)

{

    byte = byteArray.GetValue(i);

    print byte;

}

pause;

AX4 doesn't support arrays in that fashion. You can loosely type a variable as a byte array using CLRObject.

The following code works.

    CLRObject               byteArray;
    System.Text.Encoding    encoding;
    str                     string;
    int                     byte, i, arrayLength;
    ;

    string = "Sample string";
    encoding = System.Text.Encoding::get_UTF8();
    byteArray = encoding.GetBytes(string);

    arrayLength = byteArray.get_Length();
    for (i = 0; i < arrayLength; i++)
    {
        byte = byteArray.GetValue(i);
        info(strfmt("%1", byte));
    }
