Here my (growing) collection of C# format specifier, this is not a complete list but rather a collection of specifier I needed in the past:
###Short syntax summary
```csharp
"{0,5:000;0.#;0}"
```
```plain
{
0 // The index of the displayed object
,5 // A padding of 5
000;0.#;0 // The format string
}
```
```plain
000 // The format for positive numbers (min 3 places, fill missing with zeroes)
;
0.# // The format for negative numbers (at least one digit before decimal point, maximum one after)
;
0 // The format for zeros (one digit - a zero)
```
###Align right with leading spaces
```csharp
"{0,6}" // min-width: 6 character
```
###Digits after decimal point
```csharp
"{0:0.00}" // exactly 2 digits after decimal point
"{0:0.##}" // maximal 2 digits after decimal point
```
###Align positive & negative numbers with leading zeros
```csharp
/* integer: */
"{0:0000;-000}" // min-width: 4 character
/* float: */
"{0:0000.00;-000.00}" // min-width: 4 character + 2 decimal places
```
###Remove minus sign
```csharp
"{0:0;0}"
```
###Show thousand seperator
```csharp
"{0:#,0}" // only for integer
```
###Scale numbers
```csharp
"{0:#,#}" // normal number
"{0:#,##0, kilo}" // (number/1000) kilo
"{0:#,##0,, mill}" // (number/1000/1000) million
"{0:#,##0,,, bill}" // (number/1000/1000/1000) billion
```

###Right align currency
```csharp
"{0,10:#,##0.00}" // Right aligned & always 2 decimal places
```
> **see: ** [stackoverflow.com](http://stackoverflow.com/questions/7422625/right-align-currency-in-string-format)
###Align strings
```csharp
"{0,-10}" // Left aligned, min-width: 10 chars
"{0,10}" // Right aligned, min-width: 10 chars
```
###Datetime formatting
```csharp
"s" // second
"m" // minute
"t" // AM/PM
"h" // hour (1-12)
"H" // hour (0-23)
"d" // day
"M" // month
"y" // year
"z" // timezone offset
"{0:D/M/yyyy}" // z.B.: 28/2/2013"
```
###Only show positive numbers
```csharp
"{0:#.#####;'';}"
```
###Add a prefix/suffix
```csharp
"{0:(0)}" // ( number )
"{0:_0_}" // _number_
```
###Format Hexadecimal
```csharp
"{0:X}" // z.B.: 138D5
"{0:x}" // z.B.: 138d5
"{0:X8}" // z.B.: 000138D5
"0x{0:X8}" // z.B.: 0x000138D5
```
