Problem with WebServices

[nvenkat75]

Hi,

i created the the table collection,column collection etc using C# for a windows application. this works fine for generating a dataset.

now i'm trying the same using webservices. i pass the table collection as an input parameter to generate dataset. while i build the solution/project no error occurs. while i configure the .asmx file to my windows application i get an error "System.InvalidOperationException". also i get the error message like "must implement a default accessor on the class(table collection) file as it inherits from ICollection"

What do i need to do

Thanks

Use the 'Default' keyword against your collection's default accessor, in its signature.
