WCF / ASMX :: Exposing Data Contract Without Passing As Input Or Output Parameter For Any Operation Contract?
Sep 21, 2010
I have a method in wcf which returns stream of custom object. I need to deserialize this stream at client side, but my custom class which is exposed as data contract is not visible through client proxy. When I add a dummy operation contract which returns the custome object I am able to get this custom class. I dont want to write this dummy method as there are many such custom classes.
Is there any way to expose data contract without writing any operation contract that returns or accepts data contract type object?

I have just created my first WCF service and by default it has a datacontract named "Composite type" in it. I tried adding another one but i can't see it in the client application. I have already done update web reference on my client.
Code of the data contract is below.
<ServiceContract()> _
Public Interface IDocumentService
<OperationContract()> _
<FaultContract(GetType(FaultException))> _
[Code]....

I have a lot confusion on data contract .I think Data contract will create according to the Service contract and Data Base Table. For Example Let say i have service contract and i have three table product,order,customer
[ServiceContract]
public interface IMembersService
{
[OperationContract]
void insertProductDetails(clsProduct objProduct);
//What about the return type can we make it bool
[OperationContract]
List<clsProduct> getproductInfoByID(int id);
[OperationContract]
List<clsProduct> getproductInfo();
//========================================
[OperationContract]
void insertOrderDetails(clsOrder objOrder);
//What about the return type can we make it bool
[OperationContract]
List<clsOrder> getOrderInfoByID(int id);
[OperationContract]
List<clsOrder> getOrderInfo();
//========================================
[OperationContract]
void insertCustomerDetails(clsOrder objOrder);
//What about the return type can we make it bool
[OperationContract]
List<clsOrder> getCustomerInfoByID(int id);
[OperationContract]
List<clsOrder> getCustomerInfo();
}
For this case can i create three datacontact clsProduct,clsOrder,clsCustomer .i mean data contact depends on ther service contact and the table.

i am trying to call a webmethod from a webservice within a webpart-project and just cant instanciate the class within my webservice. CongressDataExternalSoapClient wsSAP = new CongressDataExternalSoapClient(); at this line i get the following error message: Could not find default endpoint element that references contract 'com.miltenyibiotec.webservice.congress.CongressDataExternalSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application...
attention should be paid to "SoapClient" at the end of my Class-Name: "CongressDataExternal". VS cannot find the Web-Class CongressDataExternal. in other ASP.NET-Projects, its possible... but not here!!! so the only class i can see is the CongressDataExternalSoapClient. i can also see the interfaces CongressDataExternalSoap and CongressDataExternalSoapChannel. i have already added the needed entries to the webconfig:
<applicationSettings>
<Miltenyi.Complaints.Sharepoint.Properties.Settings>
<setting name="Miltenyi_Complaints_SharePoint_com_miltenyibiotec_webservice_congress_CongressDataExternal" serializeAs="String">
<value>http://webservice.miltenyibiotec.com/CongressDataExternal.asmx</value>
</setting>
</Miltenyi.Complaints.Sharepoint.Properties.Settings>
</applicationSettings>
...
<configSections>
<sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
<section name="Miltenyi.Complaints.Sharepoint.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</sectionGroup>
...
</configSections>
Miltenyi.Complaints.Sharepoint is the namespace of my sharepoint webpart project. and this entry is in my settings: Name: Miltenyi_Complaints_SharePoint_com_miltenyibiotec_webservice_congress_CongressDataExternal
Type: Webservice URL Scope: App Value: URL to my webservice... what am i doing wrong here?

I added a service reference via the add service reference method. I can see all of its services in the intellisense but when I run the project and it executes the line where I instantiate the service : MyProjectName.ServiceReferenceName.IServiceReferenceClient
client = new MyProjectName.ServiceReferenceName.ServiceReferenceClient;it throws this error:Could not find default endpoint element that references contract 'ServiceReferenceName.IServiceReferenceClient' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I was trying to read about the services that accept xml inputs and return xml outputs.. but all in vain, I couldn't find a proper tutorial and sample codes to work on..
Can anyone give some links to some nice tutorials and samples with asmx services accepting xml data and returning xml data..

im passing one input parameter to the SP, based on that parameter i have written the code like below create procedure SP1(@inpName varchar(10))
declare @where varchar(20);
if @inpName = 'ABCD'
@where = 'A';
else if @inpName = '1234'
@where = '1';
else if @inpName = 'AB12'
@where = 'A,B';
SELECT * FROM TABLE1 WHERE COLUMN1 IN(@where);
Now the above query was fine if its 'ABCD' or '1234', but if its 'AB12' then query failed.
How to resolve this issue.?

I have a class with about 5-10 methods which all my services (WCF) need to expose. What is the best way to expose all the methods in all the services keeping (DRY principle) in mind?Is interface inheritence a good design principle? e.g. public interface IBMW : ICar
{
blah();
blah();
}

I have managed to expose the MEX endpoint of my WCF service and I can access it with the address like [URL] (example) and get the WDSL. So no problem there.
However, my WCF test page shows the address wrongly by using the server's name instead of the DNS name. And if I click on the link on the test page it won't work (can't get WSDL).
The WCF test page looks like this:
MyService Service
You have created a service.
To test this service, you will need to create a client and use it to call the service.
[URL]
The WCF service is hosted in IIS6. I would like to have a test page with the correct WSDL address so users can see the WSDL quickly in the browser just by clicking on the WSDL address.
In short: How can I change the MyServerName to inter.mycompany.com on the WCF test page? Can this be specified somewhere in the Web.config?

I have a ListView displaying data from Table A using a SqlDataSource.
I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure
(The scenario is much more complex but I've left out anything not relating to this exact problem).
I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.
This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":
[Code]....
Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.
What do I use instead of the word Description to reference this column in the Parameter?
