将文本框中的十六进制值多数民众赞成转换为单个十六进制对 [英] Convert Hex Value thats in a text box to Individual Hex Pairs

问题描述

嘿人们，

我有一个奇怪的问题，我想在文本框中转换一个Hex值，并获取实际的表示形式以进行传输.例如，假设我在文本框中输入A3D56712，我想以十六进制格式获取0xA3、0xD5、0x67、0x12.

有任何想法吗?

Hey people,

Curious problem I have, I want to convert a Hex value thats in a text box and get the actual representation to transport that. For Example say I enter A3D56712 in the text box, I want to get 0xA3, 0xD5, 0x67, 0x12, in HEX form.

Any Ideas?

推荐答案

解决方案1:

Solution 1:

static string[] ToHexArray(uint value) {
    int len = sizeof(uint);
    string[] result = new string[len];
    for (int index = 0; index < len; ++index) {
        int shift = 8 * (len - index - 1);
        uint mask = (uint)byte.MaxValue << shift;
        uint masked = value & mask;   
        result[index] = ((byte)(masked >> shift)).ToString("X");
    } //loop
    return result;
}

解决方案2:

Solution 2:

static string[] ToHexArray(uint value) {
    return System.Array.ConvertAll(
        System.BitConverter.GetBytes(value),
        new System.Converter<byte, string>(
            (src) => {
                return src.ToString("X");
        }));
}

第一个解决方案将最重要的数字放在左侧(您可以轻松地在代码中对其进行更改)，第二个解决方案在右侧(组合语言样式；您无法在算法中对其进行更改，但可以稍后将其反转).您可以使用string.Format而不是ToString为每个字符串添加"0x"前缀.您可以使用:

First solution puts most significant figure at left (you can easily change it in code), second one — at right (Assembly language style; you cannot change it in algorithm but can reverse it later). You can add "0x" prefix to each string by using string.Format instead of ToString. You can use:

string[] hexArray = ToHexArray(
    uint.Parse(
        MyTextBox.Text,
        System.Globalization.NumberStyles.HexNumber));

两种解决方案都经过测试.

享受吧！

Both solutions are tested.

Enjoy!

为什么不读一次提取两个字符并在其后附加"0x"?

抱歉，放屁了.我认为您除了上面的琐碎回答之外，还想要其他东西.

请参见此处 [

Why not just read extract two characters at a time and append "0x" to it?

Sorry, brain fart. I assume you want something more than this trivial response above.
