Custom Currency symbol and decimal places using decimal.ToString("C") and CultureInfo
提问by Agamand The True
I have a problem with decimal.ToString("C")override.
Basically what I wants to do is as follows:
我有decimal.ToString("C")覆盖问题。基本上我想做的如下：
CultureInfo usCulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentCulture = usCulture;
NumberFormatInfo LocalFormat = (NumberFormatInfo)NumberFormatInfo.CurrentInfo.Clone();
LocalFormat.CurrencySymbol = "RM";
I wants to make above code a function (override ToString("C")) whereby when the following code get executed:
我想让上面的代码成为一个函数（覆盖 ToString("C")），当下面的代码被执行时：
decimal paid = Convert.ToDecimal(dr["TotalPaids"]);
lblPaids.Text = paid.ToString("C");
The results would be RM4,900.00 instead of $4,900.00
结果将是 RM4,900.00 而不是 $4,900.00
How do I create an override for decimal.ToString("C")that would solve my problem
我如何创建一个覆盖来decimal.ToString("C")解决我的问题
Thanks in advance.
提前致谢。

To get a format like RM 11,123,456.00 you also need to set the following properties
要获得像 RM 11,123,456.00 这样的格式，您还需要设置以下属性
CurrentCulture modified = new CultureInfo(Thread.CurrentThread.CurrentCulture.Name);
Thread.CurrentThread.CurrentCulture = modified;
var numberFormat = modified.NumberFormat;
numberFormat.CurrencySymbol = "RM";
numberFormat.CurrencyDecimalDigits = 2;
numberFormat.CurrencyDecimalSeparator = ".";
numberFormat.CurrencyGroupSeparator = ",";
If you do that at application startup then that should make ms-MY format like en-US but with the RM currency symbol every time you call the ToString("C")method.
如果您在应用程序启动时执行此操作，则应使 ms-MY 格式类似于 en-US，但每次调用该ToString("C")方法时都带有 RM 货币符号。

use this format string :
使用此格式字符串：
#,##0.00 $;#,##0.00'- $';0 $
#,##0.00 $;#,##0.00'- $';0 $
decimal paid = Convert.ToDecimal(dr["TotalPaids"]);
lblPaids.Text = paid.ToString("#,##0.00 $;#,##0.00'- $';0 $");

If I understand your question correctly what you want is to replace the $ with RM. If so, you need to pass the custom format...
如果我正确理解您的问题，您想要的是将 $ 替换为 RM。如果是这样，您需要传递自定义格式...
lblPaids.Text = paid.ToString("C", LocalFormat);
回答by Atish
lblPaids.Text = paid.ToString("C",usCulture.Name);
Or
或者
lblPaids.Text = paid.ToString("C",LocalFormat.Name);
must Work

You can use the Double.ToString Method (String,?IFormatProvider) https://msdn.microsoft.com/en-us/library/d8ztz0sa(v=vs.110).aspx
您可以使用 Double.ToString 方法 (String,?IFormatProvider) https://msdn.microsoft.com/en-us/library/d8ztz0sa(v=vs.110).aspx
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")) // ,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-us")) // ,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-ca")) // ,234.95
