AX 2012 X++ Consume aif web service by passing list of objects

 1- Create data contract class as below

[DataContractAttribute]

class HP_TestContract

{

    str Id;

    str Name;

[DataMemberAttribute('Id'), SysOperationDisplayOrderAttribute('1')]

public str ParamId(str _Id = Id)

{

    Id = _Id;

    return Id;

}

[DataMemberAttribute('Name'), SysOperationDisplayOrderAttribute('2')]

public str ParamName(str _Name = Name)

{

    Name = _Name;

    return Name;

}

}

2-Add an AIF service method

[SysEntryPointAttribute(true),

DataMemberAttribute("HP_TestContract"),

AifCollectionTypeAttribute("_contactList",Types::Class, classStr(HP_TestContract)),

AifCollectionTypeAttribute("return",Types::Class, classStr(HP_TestContract))]

public List HeshamList(List _contactList)

{

//_contactList = contactList;

return _contactList;

}

Convert English numbers into Arabic charchters

This artical is how to convert the English like 123456789 to ١٢٣٤٥٦٧٨٩٩٠


 public string ConvertToEasternArabicNumerals(string input)
        {
            System.Text.UTF8Encoding utf8Encoder = new System.Text.UTF8Encoding();
            System.Text.Decoder utf8Decoder = utf8Encoder.GetDecoder();
            System.Text.StringBuilder convertedChars = new System.Text.StringBuilder();
            char[] convertedChar = new char[1];
            byte[] bytes = new byte[] { 217, 160 };
            char[] inputCharArray = input.ToCharArray();
            foreach (char c in inputCharArray)
            {
                if (char.IsDigit(c))
                {
                    bytes[1] = Convert.ToByte(160 + char.GetNumericValue(c));
                    utf8Decoder.GetChars(bytes, 0, 2, convertedChar, 0);
                    convertedChars.Append(convertedChar[0]);
                }
                else
                {
                    convertedChars.Append(c);
                }
