C#实现字符串倒序的写法

本文实例为大家分享了c#字符串倒序写法的实现代码，供大家参考，具体内容如下

//string concatenation with for loop
public string reversea(string text)
{
  char[] carray = text.tochararray();
  string reverse = string.empty;
  for (int i = carray.length - 1; i > -1; i--)
  {
    reverse += carray[i];
  }
  return reverse;
}

// array.reverse function
public string reverseb(string text)
{
  char[] chararray = text.tochararray();
  array.reverse(chararray);
  return new string(chararray);
}

// push/pop stack<>
public string reversec(string text)
{
  stack resultstack = new stack();
  foreach (char c in text)
  {
    resultstack.push(c);
  }

  stringbuilder sb = new stringbuilder();
  while (resultstack.count > 0)
  {
    sb.append(resultstack.pop());
  }
  return sb.tostring();
}

// linq
public string reversed(string text)
{
  return new string(text.tochararray().reverse().toarray());
}

// stringbuilder
public string reversee(string text)
{
  char[] carray = text.tochararray();
  stringbuilder reverse = new stringbuilder();
  for (int i = carray.length - 1; i > -1; i--)
  {
    reverse.append(carray[i]);
  }
  return reverse.tostring();
}
