Int64.ToString Method
Converts the numeric value of this instance to its equivalent string representation.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Return Value
Type: System.StringThe string representation of the value of this instance, consisting of a minus sign if the value is negative, and a sequence of digits ranging from 0 to 9 with no leading zeroes.
The return value is formatted with the general numeric format specifier ("G") and the NumberFormatInfo for the current culture. To define the formatting of the Int64 value's string representation, call the Int64.ToString(String) method. To define the culture whose formatting is used in the Int64 value's string representation, call the Int64.ToString(IFormatProvider) method. To define both the format specifier and culture used in creating the string representation of an integer value, call the Int64.ToString(String, IFormatProvider) method.
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:
For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about formatting, see Formatting Types.
The following example displays an Int64 value using the default ToString() method. It also displays the string representations of the Int64 value that results from using a number of standard format specifiers. The examples are displayed using the formatting conventions of the en-US culture.
long value = -16325091; // Display value using default ToString method. Console.WriteLine(value.ToString()); // Displays -16325091 // Display value using some standard format specifiers. Console.WriteLine(value.ToString("G")); // Displays -16325091 Console.WriteLine(value.ToString("C")); // Displays ($16,325,091.00) Console.WriteLine(value.ToString("D")); // Displays -16325091 Console.WriteLine(value.ToString("F")); // Displays -16325091.00 Console.WriteLine(value.ToString("N")); // Displays -16,325,091.00 Console.WriteLine(value.ToString("X")); // Displays FFFFFFFFFF06E61D
