Hi,

Yes, you can pass your data from WCF to your .CS file but first you need to add service reference and then create the instance of your service client. After that all the accessible members will be available to calling class.

Thanks

sir i had a one more question...Actually how to execute wcf services step by step process. that means in aspx.cs file we can see each and every parameter value by break point.. like that how can we see output parameter values in wcf file... with out calling in .aspx.cs file

Hi you can not debug WCF services directly but if you have added WCF to your solution then you can press F11 to jump to WCF service method from your .CS file and can see parameter values.

Sir are u there.

in iservice.cs
[operationcontract]
list< result> method(string name);

[datacontract]
public class result
{

[DataMember]
public int no
{
get { return no;}
set { no= value; }
}
[DataMember]
public int age
{
get { return age;}
set { age= value; }
}

}

in wcf service.cs

public list< result> method( string name)
{
sqlcon
sql command type procedure name-input,no-output,age-output
result rs=new result();
rs.no=cmd.parameters["@no"].value;
rs.age=cmd.parameters["@age"].value;
list< result> rls=new list< result>;
rls.add(rs);

}

in aspx.cs file

ServiceReference2.Service1Client obj2 = new ServiceReference2.Service1Client();

calling over now i want to retrive list

list< result> = obj2.method(name.text);

now how can i retrieve data in .cs

Error 18 Cannot implicitly convert type 'sample.ServiceReference2.result[]' to 'System.Collections.Generic.List<sample.smaster.result>'

Hi,
You can return array of objects in service to overcome this problem.
e.g. Result[] as return type.

Or you can use list< result> = obj2.method(name.text).ToList(); Method to convert array to list.

list < result> is not finding in .cs file how can i get that list < result> in cs file which is declared in wcf

ntitish 1-May-13 8:40am

sir are you there....

ntitish 1-May-13 8:45am

ServiceReference2.Service1Client obj2 = new ServiceReference2.Service1Client();

for service calling it not showing any error but

when retriving list data in aspx.cs file its showing error like this

Error 18 Cannot implicitly convert type 'sample.ServiceReference2.result[]' to 'System.Collections.Generic.List'

is there any way to over come this problem

Yes you can return Array instead of List in WCF method. Then you can get easily get your data in array after that you can convert your array in list by using ToList() method.

can u give me a sample code or any example for that...........bec i already tryied ToList() method i am facing error
