Convert.ToString Method (Int32)

Converts the value of the specified 32-bit signed integer to its equivalent String representation.

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

'Declaration
Public Shared Function ToString ( _
	value As Integer _
) As String
'Usage
Dim value As Integer
Dim returnValue As String

returnValue = Convert.ToString(value)
public static String ToString (
	int value
)
public static function ToString (
	value : int
) : String

Parameters

value

A 32-bit signed integer.

Return Value

The String equivalent of the value of value.

This implementation is identical to Int32.ToString.

The following code example converts a 32-bit integer to a String with the ToString method, using default formatting.
