Using Application DLL in WCF

From your error message it looks like PCSMVC.Country[] is an array. It looks like you are trying to use it as if it is an object. What is the definition for PCSMVC.Country ? Is it a collection or a single object with properties.

Also, you initialize your list and try accessing first object in list when you haven't added anything to the list yet, I would imagine if it reached that line of code you would get an index out of range error, since the list contains no items.


public List<pcsmvc.country> GetCountry()
{

List<pcsmvc.country> lst = new List<pcsmvc.country>();
//should add an object of pcsmvc.country (can initialize properties also)
lst.Add(new pcsmvc.country() { CountryName = "India" });
return lst;
}
or you can do it this way...


public List<pcsmvc.country> GetCountry()
{

List<pcsmvc.country> lst = new List<pcsmvc.country>();
//should add an object of pcsmvc.country
lst.Add(new pcsmvc.country());
//now the list contains the object and you can access it
lst[0].CountryName = "India";
return lst;
}
