C# Currency Formatting

Is there any way to format a number in the currency format (in the current Culture) using a custom format string?
For example:
1525.00 -> $1,525 (no trailing zeros)
1525.25 -> $1,525.25 (show decimals only when necessary)
We have tried different formats but none of them can produce the above.

As far as I know, no, you can't do that with a "one" format since you don't want show decimal parts for the first one but you "want" to show decimals part for the second one. I don't think there will be a "simple" format for both.
You can check the Currency format specifier (C) for that as;
var v = 1525.00;
$"{v:C0}".Dump();
returns $1,525 and
var v = 1525.25;
$"{v:C2}".Dump();
return $1,525.25.
Just a note, string interpolation uses CurrentCulture settings and in that case, I assume your current culture is somewhat based on english-based or InvariantCulture for generate CurrencySymbol, NumberGroupSeparator and NumberDecimalSeparator as $, , and . respectively.

Does this count?
static string MyCustomCurrencyString(decimal d) => d % 1 == 0 ? $"{d:C0}" : $"{d:C2}";
Let's test it:
Console.WriteLine(ZerosAreBad(1525));
Console.WriteLine(ZerosAreBad(1525.25m));
It works!
$1,525
$1,525.25

String.Format an integer to use a thousands separator with decimal value in danish culture

I have a string totalPRice which holds a value like this 1147,5
I want two things.
1)round the value so that there is always two digits after ,
2)Implement thousands separator in this string, So that final out put will be some thing like this 1.147,50
I have tried some thing like this
String.Format("{0:0.00}", totalPRice)
It does my first requirement correctly by producing an output 1147,50.
But I am way behind in my second requirement. Can any one tell me how I can achieve this?
Note: In danish culture . stands for , and , stands for .

You can refer to Standard Numeric Format Strings and use
string.Format("{0:N2}", 1234.56)
You may also specify the culture manually, if danish is not your default culture:
var danishCulture = CultureInfo.CreateSpecificCulture("da-DK");
string.Format(danishCulture, "{0:N2}", 1234.56);
see MSDN Reference for CultureInfo

You should create a culture-specific CultureInfo object and use it when converting the number into a string. Also, you can set the default culture for your whole program.
Then, your code will look like this:
// create Dennmark-specific culture settings
CultureInfo danishCulture = new CultureInfo("da");
// format the number so that correct Danish decimal and group separators are used
decimal totalPrice = 1234.5m;
Console.WriteLine(totalPrice.ToString("#,###.##", danishCulture));
Note that . and , in the formatting string are specified opposit as you want. This is because they identify decimal and group separators, and are replaced with the correct culture specific-ones.

Try this:
String.Format("{0:N2}", totalPRice)
Another possibility is to use the ToString(string format) overload.
totalPRice.ToString("N2");

If this is a currency value (money!), then it's better to use the current format specifier 'C' or 'c':
string.Format("{0:C}", 1234.56)
Normally I don't write the number of decimal digits since it comes from the international configuration.
You may way to use a different colture specifier if you don't want to use the default one.
var colture = CultureInfo.CreateSpecificCulture("§§§§§");
string.Format(culture, "{0:C}", 1234.56);
where §§§§§ is the string that identifies the desired colture.

Try this for Price format. Put it under template field instead of BoundField.
<%#(decimal.Parse(Eval("YourDataField").ToString())).ToString("N2")%>

How to format string with floating point?

In database I have a PRICE field type of float with value 54342.76 and I want to display it on gridview as 54,342.76. How can format this values?

Try
float f = 54342.76F;
string s = f.ToString("0,0.000", CultureInfo.InvariantCulture);
Console.WriteLine(s);
You could use c specifier instead, however it prints currency sign also.
Use CultureInfo.InvariantCulture as in some localizations , thousands separator may be missing.
Also read Decimal.ToString Method, Standard Numeric Format Strings, Custom Numeric Format Strings

this is what I use:
x.ToString("c")

String.Format("{0:n}", 54342.76F)
The N method is a good solution since it should respect the user's locale while others like:
String.Format("{0:#,###,###.##}", 54342.76F)
Could bypass current culture in some situations. Use {0:n0} instead of {0:n} if you want to display the number without decimals.

In the past I have used this: http://www.codeproject.com/Articles/11531/Money-DataType
It formats money perfectly when used in a DataGridView column.

Convert int to Price/Money/Currency (C#)

I have some prices in my DB which are stored as data type money and have the following code:
result.RangeMinimum = (decimal)ad.RangeMinimum;
result.RangeMaximum = (decimal)ad.RangeMaximum;
The output is:
38000
and
42000
Ideally, what I want is something [exactly] like this:
38, 000.00
and
42, 000.00
How can I achieve this? I mean, is there already an existing class out there that's built into the .NET framework or something?

What you want to achieve can be done through custom numeric format, i.e., for the
ToString() method or the String.Format() method
MDSN Custom Numeric Format

As you specified "exactly" and have a space after the coma it seems standard numeric formats will not work. You can easily customize your own format using String.Format.
Decimal number = 38000.01m;
string formatted = string.Format(CultureInfo.GetCultureInfo("en-US"), "{0:#, ###.00}", number);
// formatted now contains "38, 000.01"
Output is: 38, 000.01
Please always remember cultureinfo so us non-US citizens can enjoy apps. :)
Information on formatting with Custom Numberic Format can be found on MSDN.
Note the 00's at the end, they force two digits. Depending on your use you may or may not want this behavour. Replace with ## if required. Also if you use this in a loop don't to a culture lookup on every call to string.Format.

You can format it like
string.Format("{0:#,#.##}", decimalValue)

string currencyString = result.RangeMinimum.ToString("C", CultureInfo.CurrentCulture);

Try this
result.ToString("N");
using CultureInfo.InvariantCulture u can define your own format

Try
decimal ad.RangeMinimum = Decimal.Parse(result.RangeMinimum.ToString("#0.00"));

How to format a number 1234567 into 1,234,567 in C#?

For format options for Int32.ToString(), see standard format strings or custom format strings.
For example:
string s = myIntValue.ToString("#,##0");
The same format options can be use in a String.Format, as in
string s = String.Format("the number {0:#,##0}!", myIntValue);
Do note that the , in that format doesn't specify a "use a comma" but rather that the grouping character for the current culture should be used, in the culture-specific positions.
You also do not need to specify a comma for every position. The fact that there is a comma in the format string means that the culture-specific grouping is used.
So you get "1 234 567 890" for pl-PL or "1,23,45,67,890" for hi-IN.

var decimalValue = 1234567m;
var value = String.Format("{0:N}", decimalValue); // 1,234,567.00
or without cents
var value = String.Format("{0:N0}", decimalValue); // 1,234,567

Try
String.Format("{0:##,####,####}", 8958712551)
For Examples have a look at http://www.csharp-examples.net/string-format-double/

Using your current locale's thousands separator:
int n = 1234567 ;
n.ToString("N0");
Or, use the overload to ToString, which takes the culture as a parameter.

string formatted = string.Format("{0:##,#}", 123456789);
It depends on the culture of your computer. Some countries use commas, some countries use dots. On my computer the output was: 123.456.789
