用字符串格式伪造十进制

Question

我目前在一个小型的C#程序中有以下多项.

long one = 1;
long two = 1005;
long three = 100000005;
long four = 1111112258552;

我想将它们格式化为一个字符串,这样它们就是大小的千分之一,而不是将值除以千.

例

Input               :               Output
1                                    0.001
1005                                 1.005
100000005                       100000.005
1111112258552               1111112258.552

我已经尝试了字符串格式,例如{0:0,000},{0:0.000}但是没有提供我之后的结果.

我怎样才能达到我追求的结果？任何提示或指示将不胜感激

一些示例代码

long one = 1;
long two = 1005;
long three = 100000005;
long four = 1111112258552;

string format = "{0:0,000}";
string s1 = String.Format(format, one);
string s2 = String.Format(format, two);
string s3 = String.Format(format, three);
string s4 = String.Format(format, four);

Console.WriteLine(s1);
Console.WriteLine(s2);
Console.WriteLine(s3);
Console.WriteLine(s4);

Answer 1

尝试使用"{0:0,.000}"作为格式.

long one = 1;
long two = 1005;
long three = 100000005;
long four = 1111112258552;
string format = "{0:0,.000}";
string s1 = String.Format(format, one);
string s2 = String.Format(format, two);
string s3 = String.Format(format, three);
string s4 = String.Format(format, four);

Console.WriteLine(s1);
Console.WriteLine(s2);
Console.WriteLine(s3);
Console.WriteLine(s4);

控制台输出:

0.001
1.005
100000.005
1111112258.552
