Convert::ToUInt64 Method (String)
Converts the specified string representation of a number to an equivalent 64-bit unsigned integer.
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] public: static unsigned long long ToUInt64( String^ value )
Parameters
- value
- Type: System::String
A string that contains the number to convert.
Return Value
Type: System::UInt64A 64-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is nullptr.
| 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 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.
