Convert::ToString Method (Int64, Int32)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Converts the value of a 64-bit signed integer to its equivalent string representation in a specified base.

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

static String^ ToString(
	long long value,
	int toBase


Type: System::Int64

The 64-bit signed integer to convert.

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.

Exception Condition

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

If value is positive and toBase is not 10, the returned string uses sign-and-magnitude representation. If value is negative and toBase is not 10, the returned string uses two's complement representation. This means that the high-order bit of the highest-order byte (bit 63) is interpreted as the sign bit. If the ToString(Int64, 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::ToInt64(String^, Int32) and Int64::Parse(String^, NumberStyles).

The following example converts each element in a long integer array to its equivalent binary, hexadecimal, decimal, and hexadecimal string representations.
