I´m trying to use an external XML file to map the output from a stored procedure into an instance
of a class. The problem is that my class is
of a generic type:
public class MyValue<T>
{
public T Value
{
get;
set;
}
}
Searching through a lot
of blogs an articles I've managed to get this:
<?xml version="1.0" encoding="utf-8" ?>
<Database Name="" xmlns="http://schemas.microsoft.com/linqtosql/mapping/2007">
<Table Name="MyValue" Member="MyNamespace.MyValue`1" >
<Type Name="MyNamespace.MyValue`1">
<Column Name="Category" Member="Value" DbType="VarChar(100)" />
</Type>
</Table>
<Function Method="GetResourceCategories" Name="myprefix_GetResourceCategories" >
<ElementType Name="MyNamespace.MyValue`1"/>
</Function>
</Database>
The MyNamespace.MyValue`1 trick works fine, and the class is recognized. I expect
four rows from the stored procedure, and I'm getting
four MyValue<string> instances, but the big problem is that the property Value for the all
four instances is null. The property is not getting mapped and I don't really get why. Maybe worth noting that the property Value is generic, and that when the mapping is done using attributes it works perfect.
Anyone have a clue?
BTW the method GetResourceCategories:
public ISingleResult<MyValue<string>> GetResourceCategories()
{
IExecuteResult result = this.ExecuteMethodCall(
this,
(MethodInfo)MethodInfo.GetCurrentMethod());
return (ISingleResult<MyValue<string>>)result.ReturnValue;
}
