Which default value for var type AlignmentSubEntity ?

[joantopo]

I´m using C# and I must put a value for a new declared var.

If I have:

AlignmentSubEntity alignSubEnt;

which value do I put?

AlignmentSubEntity alignSubEnt = ..........  ;

I´m trying to do this:

http://adndevblog.typepad.com/infrastructure/2012/05/list-all-alignment-entities.html

But in C# doesn´t recognize "alignSubEnt".

How would it be this block in C#? 

Dim subEntCount As Integer = alignEnt.SubEntityCount
          For i As Integer = 0 To subEntCount - 1 'for each subentity
            'get the type
            Dim alignSubEnt As AlignmentSubEntity = alignEnt(i)
            Select Case alignSubEnt.SubEntityType
              Case AlignmentSubEntityType.Arc
                'ARC
                Dim alignSubEntArc As AlignmentSubEntityArc = _
                  alignSubEnt
              Case AlignmentSubEntityType.Line
                'LINE
                Dim alignSubEntLine As AlignmentSubEntityLine = _
                  alignSubEnt
              Case AlignmentSubEntityType.Spiral
                'SPIRAL
                Dim alignSubEntSpiral As AlignmentSubEntitySpiral = _
                  alignSubEnt
            End Select
         Next

coded on the fly, but should be close.

int subentcount = alignEnt.SubEntityCount;
for (int i = 0; subentcount - 1; i++)
{
  AlignmentSubEntity alignSubEnt = (AlignmentSubEntity)alignEnt[i];
  switch (alignSubEnt.SubEntityType)
  {
    case AlignmentSubEntityType.Arc:
      //do whatever with the arc subent
      break;
    case AlignmentSubEntityType.Line:
      //do whatever with the line subent
      break;
    case AlignmentSubEntityType.Spiral:
      //do whatever with the spiral subent
      break;
  }
}

Great!!

All right.

Thannnnnnk you.

I didn´t understand this line: 

AlignmentSubEntity alignSubEnt = (AlignmentSubEntity)alignEnt[i];

[joantopo]

Sorry.

Could you say me what default value for var "linea"?

                                switch (alignSubEnt.SubEntityType)
                                {

                                    case AlignmentSubEntityType.Line:
                                        //LINE

                                     AlignmentSubEntityLine linea ;

                                        subEntidad.Direction = linea.Direction; //acimut
                                        
                                        break;  

 I am using a list with properties (class subEntidad)

[joantopo]

Maybe this...

AlignmentSubEntityLine linea = (AlignmentSubEntityLine)alignSubEnt ;

[Jeff_M]

Yes, that should work. Then get the Direction from linea.
