why this wierd convert double to string happens?

I use win 8.1 ,visual studio 2019 in laptop it is wierd.
i use win 10 , visual studio 2019 in PC and it is ok.

What I have tried:

C#

double d=1.2;
string sWierd =""+d;//s=1/2
string sOk=d.ToString();//s=1.2

//both are not "1.2" for me so that is weird.
//weird one is "1/2". it changes dot to foreslash

What are you talking "weird"? There's nothing weird going on. Both strings are "1.2".

If you're talking about doing this:

C#

string sWeird = "" + d;

and wondering why it's working, it's because the .ToString() is being implicitly called on d to make the expression string.Empty + d work.

Solution 2

In Persian, a slash is a decimal separator

Decimal separator - Wikipedia[^]

My guess would be that one method is using your locale and the other is not, for some reason?

Sounds like one method finds the default and one uses the current setting? Sounds like an interesting C# bug......
