The ToULong method is a static extension method provided by the SandboxSystemExtensions class. It is used to convert a string representation of a number into a 64-bit unsigned integer (UInt64). If the conversion fails, it returns a default value specified by the caller.
To use the ToULong method, call it on a string instance that you want to convert to a UInt64. Provide a default value that will be returned if the conversion is not successful.
This method is particularly useful when you want to safely parse a string to a UInt64 without throwing exceptions for invalid input.
string numberString = "123456789"; ulong defaultValue = 0; ulong result = numberString.ToULong(defaultValue); // result will be 123456789 if the conversion is successful. // If the string cannot be converted, result will be 0 (the default value).
