需要将字符串/字符转换为ASCII值 [英] Need to convert string/char to ascii values

问题描述

我需要将char转换为十六进制值.请参阅Ascii表，但下面列出了一些示例:

I need to convert char to hex values. Refer to the Ascii table but I have a few examples listed below:

• 字符1 = 31 2 = 32 3 = 33 4 = 34 5 = 35 A = 41 a = 61等

• char 1 = 31 2 = 32 3 = 33 4 = 34 5 = 35 A = 41 a = 61 etc

因此，字符串str ="12345"; 需要获取转换后的str ="3132333435"

Therefore string str = "12345"; Need to get the converted str = "3132333435"

推荐答案

我认为这就是您所需要的:

I think this is all you'll need:

string finalValue;
byte[] ascii = Encoding.ASCII.GetBytes(yourString);
foreach (Byte b in ascii) 
{
  finalValue += b.ToString("X");
}

十六进制:

string finalValue;
int value;
foreach (char c in myString)
{
  value = Convert.ToInt32(c);
  finalValue += value.ToString("X"); 
  // or finalValue = String.Format("{0}{1:X}", finalValue, value);
}
// use finalValue
