如何将字符串格式化为金钱

Question

我有一个字符串000000000100,我想转换为1.00,反之亦然.

前导零将被删除,最后两位是小数.

我举一个例子:

000000001000 <=> 10.00
000000001005 <=> 10.05
000000331150 <=> 3311.50

下面是我正在尝试的代码,它给我的结果没有小数:

amtf = string.Format("{0:0.00}", amt.TrimStart(new char[] {'0'}));

Answer 1

将字符串转换为小数,然后将其除以100并应用货币格式字符串:

string.Format("{0:#.00}", Convert.ToDecimal(myMoneyString) / 100);

编辑为根据请求删除货币符号并转换为十进制.

Answer 2

您需要先将其转换为小数,然后使用货币格式对其进行格式化.

EX:

decimal decimalMoneyValue = 1921.39m;
string formattedMoneyValue = String.Format("{0:C}", decimalMoneyValue);

Answer 3

decimal value = 0.00M;
value = Convert.ToDecimal(12345.12345);
Console.WriteLine(value.ToString("C"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C1"));
//OutPut : $12345.1
Console.WriteLine(value.ToString("C2"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C3"));
//OutPut : $12345.123
Console.WriteLine(value.ToString("C4"));
//OutPut : $12345.1234
Console.WriteLine(value.ToString("C5"));
//OutPut : $12345.12345
Console.WriteLine(value.ToString("C6"));
//OutPut : $12345.123450

控制台输出:

有用!

decimal moneyvalue = 1921.39m; 
string html = String.Format("Order Total: {0:C}", moneyvalue); 
Console.WriteLine(html);

产量

Order Total: $1,921.39

Answer 5

将字符串设置为double/decimal后,将其转换为特定语言环境使用的正确格式

double amount = 1234.95;

amount.ToString("C") // whatever the executing computer thinks is the right fomat

amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-ie"))    //  €1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("es-es"))    //  1.234,95 € 
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-GB"))    //  £1,234.95 

amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-au"))    //  $1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-us"))    //  $1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-ca"))    //  $1,234.95

尝试像这样简单

 var amtf = $"{Convert.ToDecimal(amt):#0.00}";
