[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

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
)

Parameters

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.

ExceptionCondition
FormatException

The format parameter is invalid.

The format parameter can be any valid standard numeric format specifier, or any combination of custom numeric format specifiers. If format is equal to String..::..Empty or is nullNothingnullptrunita null reference (Nothing in Visual Basic), the return value of the current UInt16 object is formatted with the general format specifier ("G"). If format is any other value, the method throws a FormatException.

The format of the returned string is determined by the NumberFormatInfo object for the current culture. Depending on the format parameter, this object controls symbols such as the group separator and the decimal point symbol in the output string. To provide formatting information for cultures other than the current culture, call the ToString(String, IFormatProvider) overload.
