Convert::ToUInt64 Method (String^)

 

Converts the specified string representation of a number to an equivalent 64-bit unsigned integer.

This API is not CLS-compliant.

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

public:
[CLSCompliantAttribute(false)]
static unsigned long long ToUInt64(
	String^ value
)

Parameters

value
Type: System::String^

A string that contains the number to convert.

Return Value

Type: System::UInt64

A 64-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is null.

Exception Condition
FormatException

value does not consist of an optional sign followed by a sequence of digits (0 through 9).

OverflowException

value represents a number that is less than UInt64::MinValue or greater than UInt64::MaxValue.

Using the ToInt64(String^) method is equivalent to passing value to the Int64::Parse(String^) method. value is interpreted by using the formatting conventions of the current thread culture.

If you prefer not to handle an exception if the conversion fails, you can call the UInt64::TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.

The following example interprets the elements of a string array as numeric strings and attempts to convert them to unsigned long integers.
