如何正確顯示EXE文件的內容「C:/Path/To/File.exe」以十六進制格式?到目前爲止,我有:十六進制轉儲EXE文件
byte[] BytArr = File.ReadAllBytes("C:/Path/To/File.exe")
我使用開關聲明(這裏沒有顯示),讀取每幾個字節,並應該輸出相應的十六進制代碼,但它失敗嘗試。我該怎麼辦?如果有人能幫助我,我將不勝感激。
要注意的是,答案代碼格式不正確,是相當低效(來源:https://www.codeproject.com/articles/36747/quick-and-dirty-hexdump-of-a-byte-array),但我沒有作出努力,正確格式化。 應答代碼:
using System.Text;
namespace HexDump
{
class Utils
{
public static string HexDump(byte[] bytes, int bytesPerLine = 16)
{
if (bytes == null) return "<null>";
int bytesLength = bytes.Length;
char[] HexChars = "ABCDEF".ToCharArray();
int firstHexColumn =
8 // 8 characters for the address
+ 3; // 3 spaces
int firstCharColumn = firstHexColumn
+ bytesPerLine * 3 // - 2 digit for the hexadecimal value and 1 space
+ (bytesPerLine - 1)/8 // - 1 extra space every 8 characters from the 9th
+ 2; // 2 spaces
int lineLength = firstCharColumn
+ bytesPerLine // - characters to show the ascii value
+ Environment.NewLine.Length; // Carriage return and line feed (should normally be 2)
char[] line = (new String(' ', lineLength - Environment.NewLine.Length) + Environment.NewLine).ToCharArray();
int expectedLines = (bytesLength + bytesPerLine - 1)/bytesPerLine;
StringBuilder result = new StringBuilder(expectedLines * lineLength);
for (int i = 0; i < bytesLength; i += bytesPerLine)
{
line[0] = HexChars[(i >> 28) & 0xF];
line[1] = HexChars[(i >> 24) & 0xF];
line[2] = HexChars[(i >> 20) & 0xF];
line[3] = HexChars[(i >> 16) & 0xF];
line[4] = HexChars[(i >> 12) & 0xF];
line[5] = HexChars[(i >> 8) & 0xF];
line[6] = HexChars[(i >> 4) & 0xF];
line[7] = HexChars[(i >> 0) & 0xF];
int hexColumn = firstHexColumn;
int charColumn = firstCharColumn;
for (int j = 0; j < bytesPerLine; j++)
{
if (j > 0 && (j & 7) == 0) hexColumn++;
if (i + j >= bytesLength)
{
line[hexColumn] = ' ';
line[hexColumn + 1] = ' ';
line[charColumn] = ' ';
}
else
{
byte b = bytes[i + j];
line[hexColumn] = HexChars[(b >> 4) & 0xF];
line[hexColumn + 1] = HexChars[b & 0xF];
line[charColumn] = (b < 32 ? '·' : (char)b);
}
hexColumn += 3;
charColumn++;
}
result.Append(line);
}
return result.ToString();
}
}
}
你們是不是要轉儲文件中的特定格式? – Tectrendz
最好是一個字符串,但對我來說並不重要。謝謝。 – ComputersAreCool
