如何将字符串格式化为金钱

Question

我有一个像000000000100这样的字符串，我希望将其转换为1.00，反之亦然。

前导零将被删除，最后两位是小数。

我举了更多例子：

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，然后除以100并应用货币格式字符串：

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

根据要求编辑删除货币符号，然后转换为十进制。

Answer 2

首先需要将其转换为小数，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);

一个工作示例：https://dotnetfiddle.net/soxxuW

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：

Answer 4

有效！

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

输出

Order Total: $1,921.39

Answer 5

将字符串设置为double / decimal以使其成为特定区域设置的正确格式

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

Answer 6

    string s ="000000000100";
    decimal iv = 0;
    decimal.TryParse(s, out iv);
    Console.WriteLine((iv / 100).ToString("0.00"));

Answer 7

尝试这样简单

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

Answer 8

//Extra currency symbol and currency formatting: "€3,311.50":
String result = (Decimal.Parse("000000331150") / 100).ToString("C");

//No currency symbol and no currency formatting: "3311.50"
String result = (Decimal.Parse("000000331150") / 100).ToString("f2");

Answer 9

首先将字符串解析为小数。

Answer 10

你也可以这样做：

string.Format("{0:C}", amt)

Answer 11

尝试这样的事情：

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

Answer 12

var tests = new[] {"000000001000", "000000001005", "000000331150"};
foreach (var test in tests)
{
    Console.WriteLine("{0} <=> {1:f2}", test, Convert.ToDecimal(test) / 100);
}

由于你没有要求货币符号，我使用了“f2”代替“C”

Answer 13

尝试

amtf =  amtf.Insert(amtf.Length - 2, ".");

Answer 14

就我而言，我使用这种字符串格式从没有符号的十进制值中显示货币。

字符串格式：

string.Format("{0:#,##0.00}", decimalValue)

示例：

var decimalNumbers = new decimal[] { 1M, 10M, 100M, 1000M,10000M,100000M,1000000M,1000000000M };          

foreach (var decimalNumber in decimalNumbers)
{
   Console.WriteLine(string.Format("{0:#,##0.00}", decimalNumber));
}
