long.Parse() C#

Question

How would I convert a string, say "-100,100", to long in C#. I currently have a line of code which is ``` long xi = long.Parse(x, System.Globalization.NumberStyles.AllowThousands); ``` but this breaks when x is "a negative number". My approach: ``` long xi = long.Parse("-100,253,1", System.Globalization.NumberStyles.AllowLeadingSign & System.Globalization.NumberStyles.AllowThousands); ``` was wrong, as it broke.

Accepted Answer

give this a go:

```
long xi = long.Parse(x, System.Globalization.NumberStyles.AllowThousands | System.Globalization.NumberStyles.AllowLeadingSign);
```

It may well be because you are declaring flags you may need to declair all possible flags that will be hit. I've just confirmed this code as working in a test project using your given string value in the question. Let me know if it meets your requirements. When declaring multiple flags in a single parameter use | instead of &
