Executing a Routine

You can also use .NET proxies to execute basic routines. For example, MyAccount contains the GETVALUE subroutine. The routine accepts a record ID, an attribute name, and a value number as arguments. It returns the corresponding piece of multivalue data. Here are the steps for executing this routine from .NET:

1. Create a Caché class and add a method, like the following, that wraps a call to the routine. Note that the Caché class need not be persistent. It contains no data and its method is a class method. The class can extend %RegisteredObjectOpens in a new tab.

   
   ClassMethod GetValue(ID As %String, ATTRNAME As %String, VNO As %String) 
    As %String
   {
     CALL GETVALUE(ID,ATTRNAME,VNO,VALUE)
     RETURN VALUE
   }   
   
   

   

2. Create a .NET proxy for the Caché class.

3. Execute the routine from your .NET code using the proxy. Here is example .NET (C#) code:

   
   String Name = MVExample.Search.GetValue(cnCache, "1", "NAME", "1");
   Console.WriteLine("NAME: {0}", Name);    
   
   

   

   Note the following about these lines of .NET code:

   • Search is the .NET proxy for the Caché class containing GetValue.

   • The Caché GetValue method is a Class Method, which projects to a C# static method. No instance of Search is required to execute it.

   • The cnCache variable represents an open CacheDatabase object.
