从字符串ascii转换为字符串Hex [英] Convert from string ascii to string Hex

问题描述

假设我有这个字符串

string str = "1234"

我需要一个将此字符串转换为此字符串的函数：

I need a function that convert this string to this string:

"0x31 0x32 0x33 0x34"  

我在网上搜索，发现很多类似的东西，但不是这个问题的答案。

I searched online and found a lot of similar things, but not an answer to this question.

推荐答案

string str = "1234";
char[] charValues = str.ToCharArray();
string hexOutput="";
foreach (char _eachChar in charValues )
{
    // Get the integral value of the character.
    int value = Convert.ToInt32(_eachChar);
    // Convert the decimal value to a hexadecimal value in string form.
    hexOutput += String.Format("{0:X}", value);
    // to make output as your eg 
    //  hexOutput +=" "+ String.Format("{0:X}", value);

}

    //here is the HEX hexOutput 
    //use hexOutput
