你如何转换成十六进制使用VB.NET为十进制？ [英] How do you convert hex to decimal using VB.NET?

问题描述

我需要十六进制转换为 VB.NET 的小数。发现在C＃中的几个例子，但是当我试图转换到VB.NET我没有成功。那我想转换为十六进制数的一个例子是A14152464C203230304232323020572F544947455234352E。

I need to convert hex to a decimal in VB.NET. Found several examples in C#, but when I tried to convert to VB.NET I was not successful. An example of a hexadecimal number that I am trying to convert is "A14152464C203230304232323020572F544947455234352E".

推荐答案

这是一个24字节（192位）数;你期待什么样的价值？

That is a 24-byte (192-bit) number; what value are you expecting?

请注意，您可以使用转换做了很多蹩脚的工作，在这里 - 例如（在C＃）：​​

Note that you can use Convert to do a lot of the grungy work here - for example (in C#):

    string hex = "A14152464C203230304232323020572F544947455234352E";
    byte[] raw = new byte[hex.Length / 2];
    for (int i = 0; i < raw.Length ; i++)
    {
        raw[i] = Convert.ToByte(hex.Substring(i * 2,2), 16);
    }

你如何从获得原来一个数量取决于你怎么想的号码是...

How you get from raw to a number depends on what you think the number is...

Visual Basic中的翻译礼貌 .net反射的（虽然-1看起来很奇怪）：

Visual Basic translation courtesy of .NET Reflector (although the "-1" looks odd):

Dim hex As String = "A14152464C203230304232323020572F544947455234352E"
Dim raw As Byte() = New Byte((hex.Length / 2)  - 1) {}
Dim i As Integer
For i = 0 To raw.Length - 1
    raw(i) = Convert.ToByte(hex.Substring((i * 2), 2), &H10)
Next i
