FUNCTION xpxDotNetInvoke (objecthandle             : INTEGER;
                          methodName               : STRING;
                          arg1, arg2, arg3, arg4,
                          arg5, arg6, arg7, arg8   : GENERIC)
                          status                   : INTEGER;

The xpxDotNetInvoke method is identical xpfDotNetInvoke except that the .Net method cannot have a return value, i.e. a void method.

The different types of input parameters are treated as follows:

sdaiINTEGER and sdaiLOGICAL are translated to int.
sdaiREAL is translated to double.
sdaiBOOLEAN is translated to bool.
sdaiSTRING, sdaiBINARY and sdaiENUMERATION is translated to string.
For objects the object id in the EDM database or EDM virtual machine is translated to int.
Aggregate of sdaiINTEGER, sdaiBOOLEAN or sdaiLOGICAL is translated to List<int>.
Aggregate of sdaiREAL is translated to List<double>.
Aggregate of sdaiSTRING, sdaiBINARY or sdaiENUMERATION is translated to List<string>.
For aggregate of objects the object id in the EDM database or EDM virtual machine of the objects is translated to List<int>.

Arguments

1	Type	Name	Comment
2	INTEGER	objecthandle	Mandatory - handle to the .NET object
3	STRING	methodName	Mandatory - method name within the .NET object
4	GENERIC	arg(n)	Optional, input parameters to the .Net method.

Example

public class Class1
{
  public Class1() 
  {
  }
  public void setListOfString(List<int> intList)
  {
      List<string> returnValue = new List<string>();
      foreach (int i in intList) {
          returnValue.Add(i.ToString());
      }

  }
   public string getString(string s)
   {
      return s;
   }
}


and the EDMexpressX method that executes the two methods in Class 1:

QUERY_FUNCTION testDotNetPlugin_1() : STRING;
   LOCAL
                               object          : INTEGER;
      resultString    : STRING;
      input           : LIST OF INTEGER;
      resultList      : LIST OF STRING;
                END_LOCAL;

   input ++ 1; input ++ 2; input ++ 3;
   object := xpfCreateDotNetObject('GuruTest.Class1');
   xpxDotNetInvoke(object, 'setListOfString', input);
   -- dotnetResult is a list of string contating 3 strings with values '1', '2' and '3'.
   result := xpfDotNetInvoke(object, 'returnString', 'Hello EPMT');
   -- result contains the string 'Hello EPMT'
   return (result);
