Int16.ToString Method (String)

Converts the numeric value of this instance to its equivalent string representation, using the specified format.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public string ToString(
	string format


Type: System.String

A numeric format string.

Return Value

Type: System.String
The string representation of the value of this instance as specified by format.

The ToString(String) method formats an Int16 value in a specified format by using a NumberFormatInfo object that represents the conventions of the current culture. If you want to use the default ("G", or general) format or specify a different culture, use the other overloads of the ToString method, as follows:

To use format

For culture

Use the overload

Default ("G") format

Default (current) culture


Default ("G") format

A specific culture

ToString(String, IFormatProvider)

The format parameter can be either a standard or a custom numeric format string. All standard numeric format strings other than "R" (or "r") are supported, as are all custom numeric format characters. If format is null or an empty string, the return value of this instance is formatted with the general numeric format specifier ("G").

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The return value of this instance is formatted with the NumberFormatInfo for the current culture.

The following example initializes two Int16 values and displays them to the console using each of the supported standard format strings and several custom format strings. The example is run with en-US as the current culture.

Int16[] values = {-23805, 32194};
string[] formats = {"C4", "D6", "e1", "E2", "F1", "G", "N1", 
                    "P0", "X4", "000000.0000", "##000.0"};
foreach (string format in formats)
   Console.WriteLine("'{0,2}' format specifier: {1,17}   {2,17}",  
// The example displays the following output to the console: 
//    'C4' format specifier:    ($23,805.0000)        $32,194.0000 
//    'D6' format specifier:           -023805              032194
