Biztalk mapping, creating string[] from string

Question

In a biztalk map, the source schema has a string and the destination schema is waiting for a array of strings.

I just need to create a string array with just one string but I can't make it.

I tried with a scripting functoid and some inline C#:

public Array ArrayBuilder(string param1)
{
    ArrayList result = new ArrayList();
    result.Add(param1);
    return result.ToArray(typeof( string ));
}

But instead of an array, the functoid outputs:

...
<recipients>System.String[]</recipients>
...

Any help?

thanks

EDIT

SOURCE SCHEMAS

Basically a list of SMS (Id, message and phone number). With a loop in the orchrestation I iterate through all the SMS and prepare a SMSSend message. this mapping will happen for each of the SMS in the list (that why I have a counter)

Phone number is the string Im having the issue

<xs:schema xmlns:tns="http://schemas.datacontract.org/2004/07/ADOSybaseWCFServices" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" elementFormDefault="qualified" targetNamespace="http://schemas.datacontract.org/2004/07/ADOSybaseWCFServices" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:complexType name="SMSBatch">
    <xs:sequence>
        <xs:element name="IDBatch" type="xs:int" /> 
        <xs:element name="SMSList" nillable="true" type="tns:ArrayOfSMS" /> 
    </xs:sequence>
</xs:complexType>
<xs:element name="SMSBatch" nillable="true" type="tns:SMSBatch" />
<xs:complexType name="ArrayOfSMS">
    <xs:sequence>
        <xs:element minOccurs="0" maxOccurs="unbounded" name="SMS" nillable="true" type="tns:SMS" /> 
    </xs:sequence>
</xs:complexType>
<xs:element name="ArrayOfSMS" nillable="true" type="tns:ArrayOfSMS" /> 
<xs:complexType name="SMS">
    <xs:sequence>
        <xs:element name="ID" type="xs:int" /> 
        <xs:element name="Message" nillable="true" type="xs:string" /> 
        <xs:element name="PhoneNumber" nillable="true" type="xs:string" /> 
    </xs:sequence>
</xs:complexType>
<xs:element name="SMS" nillable="true" type="tns:SMS" /> 

Counter:

<xs:schema xmlns:b="http://schemas.microsoft.com/BizTalk/2003" xmlns="http://SendSMS.counterSchema" targetNamespace="http://SendSMS.counterSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element default="0" name="counter" type="xs:int" /> 

DESTINATION SCHEMA

For your sanity, I won't put the whole schema, it is autogenerated from a WCF service

Recipients is the string array I want to create from the phonenumber string, since I just have one recipient per message

...
<xml>
    <complexType name="ArrayOf_soapenc_string">
        <complexContent mixed="false">
            <restriction xmlns:q1="http://schemas.xmlsoap.org/soap/encoding/" base="q1:Array">
                <attribute xmlns:d5p1="http://schemas.xmlsoap.org/wsdl/" d5p1:arrayType="q1:string[]" ref="q1:arrayType" /> 
            </restriction>
        </complexContent>
    </complexType>
    <complexType name="Submission" abstract="true">
        <sequence>
            <element xmlns:q2="http://mobicomp.com/smsexpress/webservice/server/message" name="contactLists" nillable="true" type="q2:ArrayOf_soapenc_string" /> 
            <element name="deliveryDate" nillable="true" type="dateTime" /> 
            <element name="notification" type="boolean" /> 
            <element xmlns:q3="http://schemas.xmlsoap.org/soap/encoding/" name="notificationRecipient" nillable="true" type="q3:string" /> 
            <element xmlns:q4="http://schemas.xmlsoap.org/soap/encoding/" name="notificationType" nillable="true" type="q4:string" /> 
            <element xmlns:q5="http://mobicomp.com/smsexpress/webservice/server/message" name="recipients" nillable="true" type="q5:ArrayOf_soapenc_string" /> 
            <element xmlns:q6="http://schemas.xmlsoap.org/soap/encoding/" name="sender" nillable="true" type="q6:string" /> 
            <element name="validity" type="int" /> 
        </sequence>
    </complexType>
</xml>
...

SOLVED:

I used and Scripting functoid with Inline XSLT Template

<xsl:template name="recipients">
<xsl:param name="phone" />

<recipients>
    <recipient><xsl:value-of select="$phone" /></recipient>
</recipients>

Answer 1

I would suggest that you look into using an XSLT template for the individual string values extracted by your method.

So, you create your array and for each string, go off and generate the destination Xml.

Take a look at This Link which talks about using XSLT templates in your map.

Without the destination schema, that's all I can suggest at the moment. HTH
