public override string ToString()

Return Value

Type: System.String

The string representation of the value of this instance, consisting of a negative sign if the value is negative, and a sequence of digits ranging from 0 to 9 with no leading zeroes.

The ToString() method formats an Int32 value in the default ("G", or general) format by using the NumberFormatInfo object of the current culture. If you want to specify a different format or culture, use the other overloads of the ToString method, as follows:

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

The following example displays an Int32 value using the default ToString() method. It also displays the string representations of the Int32 value that results from using a number of standard format specifiers. The examples are displayed using the formatting conventions of the en-US culture.

int value = -16325;
// Display value using default ToString method.
Console.WriteLine(value.ToString());            // Displays -16325
// Display value using some standard format specifiers.
Console.WriteLine(value.ToString("G"));         // Displays -16325
Console.WriteLine(value.ToString("C"));         // Displays ($16,325.00)
Console.WriteLine(value.ToString("D"));         // Displays -16325
Console.WriteLine(value.ToString("F"));         // Displays -16325.00
Console.WriteLine(value.ToString("N"));         // Displays -16,325.00
Console.WriteLine(value.ToString("X"));         // Displays FFFFC03B
