示例1: ByteToString
internal static string ByteToString(byte[] value, int start, int count)
{
string str = new ASCIIEncoding().GetString(value, start, count);
if (str.IndexOf("\0") != -1)
str = str.Substring(0, str.IndexOf("\0"));
return str;
}示例2: Decrypt
public static string Decrypt(string Data, byte[] Key, byte[] IV)
{
try
{
MemoryStream msDecrypt = new MemoryStream(Convert.FromBase64String(Data));
// Create a CryptoStream using the MemoryStream
// and the passed key and initialization vector (IV).
CryptoStream csDecrypt = new CryptoStream(msDecrypt,
new TripleDESCryptoServiceProvider().CreateDecryptor(Key, IV),
CryptoStreamMode.Read);
// Create buffer to hold the decrypted data.
byte[] fromEncrypt = new byte[Data.Length];
// Read the decrypted data out of the crypto stream
// and place it into the temporary buffer.
csDecrypt.Read(fromEncrypt, 0, fromEncrypt.Length);
//Convert the buffer into a string and return it.
string ReturnValue = new ASCIIEncoding().GetString(fromEncrypt);
if (ReturnValue.Contains("\0\0\0"))
{
ReturnValue = ReturnValue.Remove(ReturnValue.IndexOf("\0\0\0"));
}
return ReturnValue;
}
catch (CryptographicException e)
{
Console.WriteLine("A Cryptographic error occurred: {0}", e.Message);
return null;
}
}示例3: GetItem
public string GetItem(int row, int column)
{
if (row >= ItemCount) return "";
LVITEM item = new LVITEM();
byte[] buffer = new byte[100];
IntPtr external_buffer = window_process.AllocateMemory(buffer.Length);
item.pszText = external_buffer;
item.iItem = row;
item.iSubItem = column;
item.mask = LVIF_TEXT;
item.cchTextMax = buffer.Length;
unsafe
{
IntPtr item_pointer = new IntPtr((void*)&item);
IntPtr external_item = window_process.AllocateMemory(Marshal.SizeOf(item));
window_process.Write(item_pointer, external_item, Marshal.SizeOf(item));
Interop.SendMessage(Handle, (uint)Messages.LVM_GETITEMA, IntPtr.Zero, external_item);
window_process.Read(external_buffer, buffer, buffer.Length);
window_process.FreeMemory(external_buffer);

}
string text = new System.Text.ASCIIEncoding().GetString(buffer);
return text.Substring(0, text.IndexOf((char)0));
