Question

I have for instance the following string: “0x780000105d0e0030”
If this is not the string, I can easily get the value as follows:

ulong myValue = 0x780000105d0e0030;

which give me the value of: 8646911354832027696
However, when I want to parse it as follows:

var myValue2= Convert.ToInt64("0x780000105d0e0030",16)

which give me the value of: 8070450566607667200

Then, then myValue is different than myValue2. myValue is correct however and this is how it should work. What am I doing wrong?

Answer 1

Int64 is a signed long.

Use Convert.ToUInt64 instead:

var myValue2= Convert.ToUInt64("0x780000105d0e0030",16);
