我在哪里可以找到Python maketrans和翻译的C#等价的代码? 谢谢!

这应该会带你到处:
public class MakeTrans
{
private readonly Dictionary<char, char> d;
public MakeTrans(string intab, string outab)
{
d = Enumerable.Range(0, intab.Length).ToDictionary(i => intab[i], i => outab[i]);
//d = new Dictionary<char, char>();
//for (int i = 0; i < intab.Length; i++)
// d[intab[i]] = outab[i];
}
public string Translate(string src)
{
System.Text.StringBuilder sb = new StringBuilder(src.Length);
foreach (char src_c in src)
sb.Append(d.ContainsKey(src_c) ? d[src_c] : src_c);
return sb.ToString();
}
}
您有责任确保进出口的长度相同。您可以添加删除字母等功能。
字典构造以一种很酷的LINQ-y方式完成。它有点不明显,因此提供了注释掉的代码并执行相同的操作。
以下是它在python(example lifted from here)中的外观:
>>> from string import maketrans # Required to call maketrans function.
>>>
>>> intab = "aeiou"
>>> outtab = "12345"
>>> trantab = maketrans(intab, outtab)
>>>
>>> str = "this is string example....wow!!!";
>>> print str.translate(trantab);
th3s 3s str3ng 2x1mpl2....w4w!!!
这是C#测试代码:
static void Main(string[] args)
{
MakeTrans.MakeTrans mt = new MakeTrans.MakeTrans("aeiou", "12345");
Console.WriteLine("{0}", mt.Translate("this is string example....wow!!!"));
}
这是输出:
th3s 3s str3ng 2x1mpl2....w4w!!!
