"Unassigned Local Variable"

[tradetree]

I am getting a frustrating error "Unassigned Local Variable". I searched the forum and reviewed all related postings but don't see a solution. I have a class with two methods listed below. In the first method "update" I declare a built in type "bool retVal" and can use the variable just fine. In the second method I declare local variable "BarData fooVal". "BarData" is a valid class and I'm just trying to instantiate a local instance of this class. If I move the declaration "BarData fooVal" up to the data section of the class instead of within the method it also works fine. I don't see why built in types work differently than a class type? What am I missing?

public bool update(double price public bool update(double price){
bool retVal = false;
_bar_cnt++;
_bar_sum += price;
_com_center.setBarData( _bar_sum / _bar_cnt, _bar_start.getBar() + (_bar_cnt/2) );
if( _bar_sum > 10 ){ retVal = true; }
// Check for price outside of channel
return(retVal );
}

// Return center COM
public BarData getCOM_center( POINT pt ){
BarData fooVal;
fooVal.setBarData(0,0);
if( pt == POINT.BASE ){
fooVal.setBarData(0, 0);
return(fooVal);
}else{
fooVal.setBarData(0, 0);
return(fooVal);
}
}
bool retVal = false;
_bar_cnt++;
_bar_sum += price;
_com_center.setBarData( _bar_sum / _bar_cnt, _bar_start.getBar() + (_bar_cnt/2) );
if( _bar_sum > 10 ){ retVal = true; } // Setting retVal here works just fine.
// Check for price outside of channel
return(retVal );
}

// Return center COM
public BarData getCOM_center( int pt ){
BarData fooVal;
fooVal.setBarData(0,0); // Unassigned Local Variable here.
if( pt == 0 ){
fooVal.setBarData(0, 0);
return(fooVal);
}else{
fooVal.setBarData(0, 0);
return(fooVal);
}
}

Hello tradetree,

This is related to C# more than NinjaScript so unfortunately outside our scope of support. Perhaps another community member can offer input on this.

It also isn't clear, but it seems like you solved by moving the declaration outside the method?

Yes, I have a workaround, but it means that I also have a global variable when it should be local. It is just poor programming practice. I can't understand it from a C# perspective, but I think you are right that it is indeed some kind of C# issue.

This was a programming error on my part. I needed to use "new" to construct the local object in C#. When I declared it a class variable, then it was constructed when the class object was constructed, which is why it worked in that case. Solved.
