Unexpected character '$' when compiling

[devkin]

Hello,I am trying to compile custom script. It works fine on my laptop but on another pc, it gives an error : Unexpected character '$' when compiling
The code seems like usual string interpolation.

string text=$"line-{Time[0].ToString()}";

Any suggestions please. Thanks

Hello devkin

What version of NinjaTrader are you currently using? Interpolated Strings will only work in the newer releases of NinjaTrader past version 8.1.2.x where the newer C# version is being used.

Thank you, it was 8.1.1.x on the one that wasn't working.

Hello devkin,

Yes in that case you would need to use string.Format to do that in 8.1.1.x.

string myString = string.Format("{1}", Time[0]);

Hi, Can I get some help with this? I'm also compiling an indicator for a version before 8.1.2. The ONLY compile error I have is related to the $ listed here after string filename. Please helppp

Hello trader123456789,

This was addressed earlier in the thread, you need to either update to a newer version of NinjaTrader to use newer C# features or use the feature that is appropriate for the C# version used in that version of NinjaTrader. The alternate is String.Format and there is an example of that in post 4.
