.net将小数格式化为两个位置或一个整数

For 10 I want 10 and not 10.00 For 10.11 I want 10.11

对于10，我想要10，而不是10。11，我想要10。11

Is this possible without code? i.e. by specifying a format string alone simlar to {0:N2}

这可能没有代码吗?即，通过指定格式字符串单独简化为{0:N2}

Thanks!

谢谢!

#1

decimal num = 10.11M;

Console.WriteLine( num.ToString( "0.##" ) );

#2

It seems to me that the decimal precision is intrinsic to the decimal type, which defaults to 4 decimal places. If I use the following code:

在我看来，十进制精度是十进制类型的固有属性，它默认为小数点后4位。如果我使用以下代码:

decimal value = 8.3475M;
Console.WriteLine(value);
decimal newValue = decimal.Round(value, 2);
Console.WriteLine(newValue);

The output is:

的输出是:

8.3475
8.35
