where is the private variable for the property

[junkone]

I am old school and always had a private variable for the properties exposed via get;set; you can see

Testparameter is not referenced by any private variable.

maybe programming has changed but when I sit back and looked at this code, I did not understand how this works without a private variable.

namespace NinjaTrader.NinjaScript.Indicators
{
public class MyCustomIndicator1 : Indicator
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Indicator here.";
Name = "MyCustomIndicator1";
Calculate = Calculate.OnBarClose;
IsOverlay = false;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;
Testparameter = 1;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
//Add your custom indicator logic here.
}

#region Properties
[NinjaScriptProperty]
[Range(1, int.MaxValue)]
[Display(Name="Testparameter", Order=1, GroupName="Parameters")]
public int Testparameter
{ get; set; }
#endregion

}
}

Hello junkone,

The private backing field for a public property is a concept in C#, this can be used or not it is up to the developer. That is just used as a storage unit for your public property but if you don't have any logic in the public property there is really no point in doing that, its just extra code.

If you have a specific reason to need a body in the get/set you can use a private backing field or other variables. To learn more about this concept you could search online for "C# private backing field" or "C# public properties and backing fields".

https://docs.microsoft.com/en-us/dot...structs/fields

There is specifically an example of when a backing field is used on the following page:
https://docs.microsoft.com/en-us/dot...cts/properties


When you have just {get;set;} you can think of that as essentially the same as both making a public property and having a variable.



I look forward to being of further assistance.
