hi friend for creating a webservice add and webservice file from add new item.. its having the extension .asmx when you open it The first line of the file will look like This line will instruct the compiler to run on Web Service mode and the name of the C# class. We also need to access the Web Service namespace. It is also a good practice to add a reference to the System namespace. using System; using System.Web.Services; The SecurityWebService class should inherit the functionality of the Web Services class. Therefore we put the following line of code: public class SecurityWebService : WebService [WebMethod(Description=This method call will get the company name and the price for a given security code.EnableSession=false)] public SecurityInfo GetSecurityInfo(string Code) { AssignValues(Code); SecurityInfo SecurityDetails = new SecurityInfo(); SecurityDetails.Code = Security.Code; SecurityDetails.CompanyName = Security.CompanyName; SecurityDetails.Price = Security.Price; return SecurityDetails; } When you specify the Method attribute WebMethod then it becomes public for all. now you can view your service in broswer... You can call the Web Service directly using the HTTP GET method.The syntax for directly calling the Web Service using HTTP GET is http://server/webServiceName.asmx/functionName?parameter=parameterValue Add a discovery file now. Web Service discovery is the process of locating and interrogating Web Service descriptions which is a preliminary step for accessing a Web Service. It is not compulsory to create a discovery file for each Web Service. Here is a sample discovery file for our securities Web Service. Name is sample.disco and save it to the same directory as the Web Service. Now Deploying the Web Services from development to staging or production is very simple. Similar to ASP.NET applications just copy the .ASMX file and the .DISCO files to the appropriate directories and you are in business. Please mark Do you like this post if it helps you.
