How do I format a C# decimal to remove extra following 0's?

Question

I want to format a string as a decimal, but the decimal contains some following zeros after the decimal. How do I format it such that those meaningless 0\'s disappear?

Answer 1

double a = 1100.00
double  b =1100.1
double  c = 1100.100
double  d =1100.1000

Remove last zero after point


string stra = a.toString("0.00").TrimEnd('0').TrimEnd('.');
string strb = b.toString("0.00").TrimEnd('0').TrimEnd('.');
string strc = c.toString("0.00").TrimEnd('0').TrimEnd('.');
string strd = d.toString("0.00").TrimEnd('0').TrimEnd('.');

Output

1100
1100.1
1100.1
1100.1
