相当于java中的eval（）函数 [英] Equivalent to eval() function in java

问题描述

您好我试图评估vb.net中的以下声明，但我不知道该怎么做，所以任何人都可以帮助

我？

Hi im trying to evaluate below statement in vb.net but i don't know how to do that so anyone can help
me ?

var code = eval("(0x4247f4e627ca7065145406ab01f7f7e3)");
alert(code);

得到了结果8.810266794149574e + 37



我希望在.NET中完成这个



更新：

and got the result "8.810266794149574e+37"

I want this to be done in .NET

Update:

function getPoW(a, b) {
        var c = 0;
        do hash_hex = md5(md5(b + c)), hash = eval("(0x" + hash_hex + ")"), ++c; while (hash >= a);
        return c
}

谢谢提前：）

Thanks in advance :)

推荐答案

你在那里几乎失败了 - .NET不容易支持大于int64的数字 - 这是一个int128，它不会甚至适合小数...



有BigIntger类：

You are pretty much on a loser there - .NET does not easily support numbers larger than int64 - and that is an int128, which won't even fit in a decimal...

There is the BigIntger class:

Dim hexString As String = "4247f4e627ca7065145406ab01f7f7e3"
Dim bi As BigInteger = BigInteger.Parse(hexString, System.Globalization.NumberStyles.HexNumber)

但是否对你有用取决于什么你打算做数据......

But whether that is useful to you depends on what you are planning on doing with the data...
