Convert.ToString Method (Int16, Int32)

.NET Framework 3.5

Converts the value of a 16-bit signed integer to its equivalent string representation in a specified base.

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

Syntax

```public static string ToString(
short value,
int toBase
)
```

Parameters

value
Type: System.Int16

The 16-bit signed integer to convert.

toBase
Type: System.Int32

The base of the return value, which must be 2, 8, 10, or 16.

Return Value

Type: System.String
The string representation of value in base toBase.

Exceptions

ExceptionCondition
ArgumentException

toBase is not 2, 8, 10, or 16.

Remarks

If value is positive and toBase is 2, 8, or 16, the returned string uses sign-and-magnitude representation. If value is negative and toBase is 2, 8, or 16, the returned string uses two's complement representation. This means that the high-order bit of the high-order byte (bit 15) is interpreted as the sign bit. If the ToString(Int16, Int32) method is called to create a string that will later be converted back to a number, a corresponding method that assumes a similar numeric representation should be called to perform the conversion. Such methods include Convert.ToInt16(String, Int32) and Int16.Parse(String, NumberStyles).

Examples

The following example converts each element in an array of 16-bit signed integers to its equivalent binary, hexadecimal, decimal, and hexadecimal string representations.

```int[] bases = { 2, 8, 10, 16};
short[] numbers = { Int16.MinValue, -13621, -18, 12, 19142, Int16.MaxValue };

foreach (int baseValue in bases)
{
Console.WriteLine("Base {0} conversion:", baseValue);
foreach (short number in numbers)
{
Console.WriteLine("   {0,-8}  -->  0x{1}",
number, Convert.ToString(number, baseValue));
}
}
// The example displays the following output:
//       Base 2 conversion:
//          -32768    -->  0x1000000000000000
//          -13621    -->  0x1100101011001011
//          -18       -->  0x1111111111101110
//          12        -->  0x1100
//          19142     -->  0x100101011000110
//          32767     -->  0x111111111111111
//       Base 8 conversion:
//          -32768    -->  0x100000
//          -13621    -->  0x145313
//          -18       -->  0x177756
//          12        -->  0x14
//          19142     -->  0x45306
//          32767     -->  0x77777
//       Base 10 conversion:
//          -32768    -->  0x-32768
//          -13621    -->  0x-13621
//          -18       -->  0x-18
//          12        -->  0x12
//          19142     -->  0x19142
//          32767     -->  0x32767
//       Base 16 conversion:
