Question

I wonder if it’s possible to assign a default value for web service request input parameter. Here’s my input parameter in the wsdl:

<element name="pensionType" default="0" type="int">

In the code side I check for the value of pensionType like this:

if (pensionType!=0)
{ TODO code here}
else
{ return warning that no data found}

I tested this in Mozilla Poster. So from this I expected that if I didn’t supply any value to pensionType I’d get that warning. I get a long error:

System.Web.Services.Protocols.SoapException: Server was unable to read request. --->  
    System.InvalidOperationException: There is an error in XML document (13, 39). ---> System.FormatException: Input string was not in a correct format.    at

You can do like this:

if(pensionType != null)
{
    if (pensionType!=0)
    { TODO code here}
    else
    { return warning that no data found}
}

This may help you..!!
