year=obj.year;
}

Solution 1

in Method2 why are you creating a new object i.e.

C#

method 2()
 {
 Abc objabc=new abc(); //here you are creating new object.
 abc.getdetails();
 here i am loosing the value.. set by my parameterized constructor 
}

.

The basic rule for the parameterised constuctor is that the no. of objects of class gets created that many no. of copy of variables present inside the class gets initialised.

Here you cann't get the values of variables(using parameterised constructor) using default constructors.

Create a object of the class using parameterised constructor (with required value) globally. And use that object where-ever need comes.

no .. this is not working ..i filled the object on parameterized constructior , but like above when default constructor is called , value gets lost

public ObjectivesPdfReport()
{

}

public ObjectivesPdfReport(ExportToPdfDocument objExp)
{
objExport = new ExportToPdfDocument()
{
Connectionstring=objExp.Connectionstring,
DataForYear=objExp.DataForYear
};
}
