private char[] cutchars = "1234567890abcdefghijklmnopqrstuvwzyz ".ToCharArray();
private StringBuilder sb = new StringBuilder(5000000);

例 ，输入 wq你 vb好 kcg吗 [回车]
就输出 你好吗

String str = "1234567890abcdefghijklmnopqrstuvwzyzfg35436547";
String NewStr = "";
for (Int32 i = 0; i < str.Length; i++)
{
if ((str[i] >= 'a' && str[i] <= 'z') || (str[i] >= 'A' && str[i] <= 'Z'))
{
continue;
}
NewStr += str[i];
}
Console.WriteLine(NewStr);

String str = "abcdefzfdaf你adfsd好";
for (Int32 i = 0; i < str.Length; i++)
{
if (Convert.ToInt32(str[i]) > 122 || Convert.ToInt32(str[i])<97)
{
MessageBox.Show(Convert.ToInt32(str[i]).ToString ());
}
}

就是一很简单的算法啊
String str = "1234567890abcdefghijklmnopqrstuvwzyzfg35436547";
String NewS
