How to format string to money
提问by Alvin
I have a string like 000000000100, which I would like to convert to 1.00 and vice versa.
我有一个像 的字符串000000000100，我想将其转换为 1.00，反之亦然。
Leading zero will be remove, last two digit is the decimal.
前导零将被删除，最后两位是小数。
I give more example :
我举更多例子：
000000001000 <=> 10.00
000000001005 <=> 10.05
000000331150 <=> 3311.50
Below is the code I am trying, it is giving me result without decimal :
下面是我正在尝试的代码，它给了我没有小数的结果：
amtf = string.Format("{0:0.00}", amt.TrimStart(new char[] {'0'}));

Convert the string to a decimal then divide it by 100 and apply the currency format string:
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);
Edited to remove currency symbol as requested and convert to decimal instead.
编辑以根据要求删除货币符号并转换为十进制。

Parse to your string to a decimal first.
首先将您的字符串解析为小数。
回答by Mohammed Swillam
you will need to convert it to a decimal first, then format it with money format.
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:
前任：
decimal decimalMoneyValue = 1921.39m;
string formattedMoneyValue = String.Format("{0:C}", decimalMoneyValue);

//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");

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

Try something like this:
尝试这样的事情：
decimal moneyvalue = 1921.39m;
string html = String.Format("Order Total: {0:C}", moneyvalue);
Console.WriteLine(html);

var tests = new[] {"000000001000", "000000001005", "000000331150"};
foreach (var test in tests)
{
Console.WriteLine("{0} <=> {1:f2}", test, Convert.ToDecimal(test) / 100);
}
Since you didn't ask for the currency symbol, I've used "f2" instead of "C"
由于您没有要求提供货币符号，因此我使用了“f2”而不是“C”
