Problem with the import tag

[Eliane-3]

hello,

i'm trying to use the DataSet in my drl file that's why i'm using the import
tag in order to reference the System.Data library. But, i'm having an error
telling me that the DataSet is not well referenced.Below, the code i'm writing
in order to do the import

 <import>System</import>
  <import>System.Data</import>
  <dotnet:functions>
    public void ExtractFromDB()
    {
                DataSet dSet = new DataSet ();
    }
  </dotnet:functions>

<rule name="REA Rule">
    <parameter identifier="test">
      <dotnet:class>System.String</dotnet:class>
        </parameter>
        <dotnet:condition> test.Equals("test")</dotnet:condition>
        <dotnet:consequence>
                ExtractFromDB();
                Console.WriteLine("the dataset is true");
        </dotnet:consequence>
  </rule>
  </rule-set>


this is the error message i'm getting:
The type or namespace name 'DataSet' could not be found (are you missing a
using directive or an assembly reference?)


Thanks for ur help,

possibly try import System.Data.DataSet or else fully qualify the namespace?

In fact, i already tried this i also tried to assert an object of
type "DataSet" and i got the following error:


----
error CS0011: Referenced class 'System.Data.DataSet' has base class or
interface 'System.ComponentModel.MarshalByValueComponent' defined in an
assembly that is not referenced.  You must add a reference to assembly 'System'.
error CS0011: Referenced class 'System.Data.DataSet' has base class or
interface 'System.ComponentModel.IListr
interface 'System.Xml.Serialization.IXmlSerializable' defined in an assembly
that is not referenced.  You must add a reference to assembly 'System.Xml'.
error CS0011: Referenced class 'System.Data.DataSet' has base class or
interface 'SystemSource' defined in an assembly that is not referenced.  You
must add a reference to assembly 'System'.
error CS0011: Referenced class 'System.Data.DataSet' has base class
o.ComponentModel.ISupportInitialize' defined in an assembly that is not
referenced.  You must add a reference to assembly 'System'.

---

That's why i tried also to enter these references in my drl but i always get
the same error :( I took a look at the generated code and i realized that the
use of import tag didnt include the libraries in the generated class

 

I tried also to execute the following given example in Drools.Net and it didn't
work ..

<rule-set name="CSharpRuleSet"

    public void Sleep(int milliseconds)
    {
    Thread.Sleep(milliseconds);
    }
  </dotnet:functions>

  <rule name="SimpleRule">
    <parameter identifier="text">
      <dotnet:class>System.String</dotnet:class>
    </parameter>
    <dotnet:condition>text.Equals("Ready")</dotnet:condition>

  </rule>
</rule-set>

Eliane,

   Im not sure, but what about importing all this classes??... I dont
   know if <import>System.*</import> would work, but its worth a try.
