如何将字符串值转换为十进制

Question

There is a string values

1. 28000 Million
2. 15592 Million

1. Now I am converting these values as

decimal val=Convert.ToDecimal(28000)/1000//To convert it into billion.
Here val=28
return val.Tostring("F1");///Gives 28.0

2.

decimal val=Convert.ToDecimal(15592)/1000//To convert it into billion.
Here val=15.592
return val.Tostring("F1");///Gives 15.6

Now What I want here instead of 28.0 I want 28 15.6 is fine for me.

How can I ignore decimal in case of 28.0?

Answer 1

        var val =Convert.ToDecimal(28000) / 1000;
        Console.WriteLine(val.ToString("N")); // 28,00
        Console.WriteLine(val.ToString("F0"));  // 28
        Console.WriteLine(val.ToString("F1"));   //28,0

EDIT:

        var val =Convert.ToDecimal(15592) / 1000;
        Console.WriteLine(val.ToString("N")); // 15,59
        Console.WriteLine(val.ToString("F0"));  // 16
        Console.WriteLine(val.ToString("F1"));   //15,6

Answer 2

Just use

return val.Tostring();

Maybe this is what you want. This is without a Limitation of decimal places

Answer 3

you should try parsing to integer

 decimal val=Convert.ToDecimal(28000)/1000//To convert it into billion.
 Here val=28
 int i = 0;
 Int32.TryParse(val.ToString(), out i);

  return i ==0?  return val.Tostring("F1") :  return i.Tostring();
